14 CFR 91.713 - Operation of civil aircraft of Cuban registry.

This action amends the Special Federal Aviation Regulation (SFAR) that prohibits certain flights in specified areas of the Sanaa (OYSC) Flight Information Region (FIR) by all: United States (U.S.) air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except where the operator of such aircraft is a foreign air carrier. There has been a reduction in the level of risk to U.S. civil aviation operations in limited portions of the specified areas of the Sanaa (OYSC) Flight Information region (FIR) where the FAA had prohibited flight operations under the SFAR. As a result, the FAA is reducing the amount of airspace in the Sanaa (OYSC) FIR in which U.S. civil aviation operations are prohibited. However, there continues to be an unacceptable level of risk to U.S. civil aviation operations in the remainder of the specified areas of the Sanaa (OYSC) FIR, as described in this rule, resulting from terrorist and militant activity. Consequently, the FAA is also amending this SFAR to extend its expiration date. The FAA is also republishing, with minor revisions, the approval process and exemption information for this SFAR.

This action extends the expiration date for the Special Federal Aviation Regulation (SFAR) that prohibits certain flights in the territory and airspace of Somalia at altitudes below flight level (FL) 260 by all: United States (U.S.) air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except where the operator of such aircraft is a foreign air carrier. The FAA is taking this action because it has determined that there continues to be an unacceptable risk to U.S. civil aviation operating in the territory and airspace of Somalia at altitudes below FL260 resulting from terrorist and militant activity. The FAA also republishes, with minor revisions, the approval process and exemption information for this SFAR.

The FAA is adopting a new noise standard for certain newly certificated subsonic jet airplanes and subsonic transport category large airplanes. This noise standard, known as Stage 5, applies to any person submitting an application for a new airplane type design with a maximum certificated takeoff weight of 121,254 pounds (55,000 kg) or more on or after December 31, 2017; or with maximum certificated takeoff weight of less than 121,254 pounds (55,000 kg) on or after December 31, 2020. This change will set a lower noise limit for newly certificated airplanes and harmonize the noise certification standards for those airplanes certificated in the United States with those certificated under international standards.

The FAA is correcting a final rule published on August 29, 2017. In that final rule, which became effective on the date of publication, the FAA reissued a prohibition of certain flight operations in the Damascus (OSTT) Flight Information Region (FIR) by all U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except such persons operating a U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except where the operator is a foreign air carrier. The FAA inadvertently failed to include an Amendment Number for that final rule. This document corrects that error.

This action reissues a prohibition of certain flight operations in the Damascus (OSTT) Flight Information Region (FIR) by all U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except such persons operating a U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except where the operator is a foreign air carrier. The FAA finds that this action is necessary to safeguard against continuing hazards to persons and aircraft engaged in such flight operations.

This rule better aligns FAA regulations regarding the North Atlantic (NAT) Minimum Navigation Performance Specifications (MNPS) with the relevant International Civil Aviation Organization (ICAO) standards. The ICAO NAT Region is transitioning from the decades-old MNPS navigation specification to a more modern, Performance-Based Navigation (PBN) specification. This rule also incorporates by reference the current version of Annex 2 (“Rules of the Air”) to the Convention on International Civil Aviation (the “Chicago Convention”), hereinafter referred to as “ICAO Annex 2,” in the FAA's regulations.

This proposal would revise the FAA's requirements for application to operate in RVSM airspace. The proposal would eliminate the requirement for operators to apply for an RVSM authorization when their aircraft are equipped with qualified ADS-B Out systems and meet specific altitude keeping equipment requirements for operations in RVSM airspace. This proposal recognizes the enhancements in aircraft monitoring resulting from the use of ADS-B Out systems and responds to requests to eliminate the burden and expense of the current RVSM application process for operators of aircraft equipped with qualified ADS-B Out systems.

The FAA is withdrawing a previously published NPRM that proposed to revise the temporary flight restriction (TFR) provision for space flight operations to make the restrictions applicable to all aircraft including non-U.S. registered aircraft, instead of only U.S. registered aircraft or aircraft flown by pilots using a FAA pilot certificate. The NPRM also proposed to amend language for consistency with other TFR provisions and commercial space regulations and definitions by replacing “space flight operations” with “launch, reentry, or amateur rocket operations.” The intended effect of the proposed action was to further enhance the safety in the affected airspace and improve the readability of the TFR requirements. After further review of this action and the changing technology and scope of new flight operations, the FAA determined that a better assessment of TFRs in the National Air Space (NAS) is needed to address present day operations; therefore, it is withdrawing this NPRM.

The FAA is correcting a final rule published on September 7, 2016. In that rule, the FAA amended its regulations to relocate and update the content of SFAR No. 108 to the newly created subpart N of part 91 in order to improve the safety of operating the Mitsubishi Heavy Industries (MHI) MU-2B series airplane. This document corrects two errors in the codified text of the final rule.

This action extends the prohibition of flight operations in the Tripoli (HLLL) Flight Information Region (FIR) by all U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating a U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except operators of such aircraft that are foreign air carriers. The extension of the expiration date is necessary due to continued hazards to persons and aircraft engaged in such flight operations. This Special Federal Aviation Regulation (SFAR) will now remain in effect until March 20, 2019.

On December 13, 2016, the Federal Aviation Administration (FAA) published a final rule to permit operators to use an enhanced flight vision system in lieu of natural vision to continue descending from 100 feet above the touchdown zone elevation to the runway and to land on certain straight-in instrument approach procedures under instrument flight rules. The FAA is delaying the effective date of this final rule.

This final rule will allow airmen to exercise pilot in command privileges in certain aircraft without holding a current medical certificate. This rule, which conforms FAA regulations with legislation, is intended to ensure that pilots who complete a medical education course, meet certain medical requirements, and comply with aircraft and operating restrictions are allowed to act as pilot in command for most part 91 operations.

The FAA amends its airworthiness standards for normal, utility, acrobatic, and commuter category airplanes by replacing current prescriptive design requirements with performance-based airworthiness standards. These standards also replace the current weight and propulsion divisions in small airplane regulations with performance- and risk-based divisions for airplanes with a maximum seating capacity of 19 passengers or less and a maximum takeoff weight of 19,000 pounds or less. These airworthiness standards are based on, and will maintain, the level of safety of the current small airplane regulations, except for areas addressing loss of control and icing, for which the safety level has been increased. The FAA adopts additional airworthiness standards to address certification for flight in icing conditions, enhanced stall characteristics, and minimum control speed to prevent departure from controlled flight for multiengine airplanes. This rulemaking is in response to the Congressional mandate set forth in the Small Airplane Revitalization Act of 2013.

This action extends the prohibition of certain flight operations in the Damascus (OSTT) Flight Information Region (FIR) by all U.S. air carriers; U.S. commercial operators; persons exercising the privileges of a U.S. airman certificate, except when such persons are operating a U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when such operators are foreign air carriers. The FAA finds that this action continues to be necessary to address a potential hazard to persons and aircraft engaged in such flight operations.

The FAA is withdrawing a previously published advance notice of proposed rulemaking that sought public comment from interested persons involving glider operations in the National Airspace System. The action responded to recommendations from members of Congress and the National Transportation Safety Board and was intended to gather information to determine whether the current glider exception from transponder equipage and use provides the appropriate level of safety in the National Airspace System. The FAA is withdrawing that action because the limited safety benefit gained does not justify the high cost of equipage.

Prior to this final rule, persons could only use an Enhanced Flight Vision System (EFVS) in lieu of natural vision to descend below the decision altitude, decision height, or minimum descent altitude (DA/DH or MDA) down to 100 feet above the touchdown zone elevation (TDZE) using certain straight-in landing instrument approach procedures (IAPs). This final rule permits operators to use an EFVS in lieu of natural vision to continue descending from 100 feet above the TDZE to the runway and to land on certain straight-in IAPs under instrument flight rules (IFR). This final rule also revises and relocates the regulations that permit operators to use an EFVS in lieu of natural vision to descend to 100 feet above the TDZE using certain straight-in IAPs. Additionally, this final rule addresses provisions that permit operators who conduct EFVS operations under parts 121, 125, or 135 to use EFVS-equipped aircraft to dispatch, release, or takeoff under IFR, and revises the regulations for those operators to initiate and continue an approach, when the destination airport weather is below authorized visibility minimums for the runway of intended landing. This final rule establishes pilot training and recent flight experience requirements for operators who use EFVS in lieu of natural vision to descend below the DA/DH or MDA. EFVS-equipped aircraft conducting operations to touchdown and rollout are required to meet additional airworthiness requirements. This final rule also revises pilot compartment view certification requirements for vision systems using a transparent display surface located in the pilot's outside field of view. The final rule takes advantage of advanced vision capabilities, thereby achieving the Next Generation Air Transportation System (NextGen) goals of increasing access, efficiency, and throughput at many airports when low visibility is the limiting factor. Additionally, it enables EFVS operations in reduced visibilities on a greater number of approach procedure types while maintaining an equivalent level of safety.

This action extends the prohibition against certain flight operations in the Simferopol (UKFV) and Dnipropetrovsk (UKDV) flight information regions (FIRs) by all United States (U.S.) air carriers; U.S. commercial operators; persons exercising the privileges of a U.S. airman certificate, except when such persons are operating a U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when such operators are foreign air carriers. The FAA finds this action to be necessary to address a continuing hazard to persons and aircraft engaged in such flight operations.

The Federal Aviation Administration proposes to modify the requirements primarily applicable to air carriers conducting domestic, flag and supplemental operations to enhance the professional development of pilots in those operations. The proposal would require air carriers conducting domestic, flag and supplemental operations to provide new-hire pilots with an opportunity to observe flight operations (operations familiarization) to become familiar with procedures before serving as a flightcrew member in operations; revise the upgrade curriculum; provide leadership and command and mentoring training for all pilots in command (PICs); and establish Pilot Professional Development Committees (PPDC). This proposal is responsive to a statutory requirement for the Federal Aviation Administration to convene an aviation rulemaking committee (ARC) to develop procedures for air carriers pertaining to pilot mentoring, professional development, and leadership and command training and to issue an NPRM and final rule based on these recommendations. The proposal also includes a number of additional conforming changes related to flight simulation training devices and second in command (SIC) pilot training and checking, and other miscellaneous changes. The FAA believes that this proposed rule would mitigate incidents of unprofessional pilot behavior which would reduce pilot errors that can lead to a catastrophic event.

This rulemaking proposes to harmonize the FAA's regulations regarding the North Atlantic (NAT) Minimum Navigation Performance Specifications (MNPS) with those of the International Civil Aviation Organization (ICAO). ICAO's NAT Region is transitioning from the decades-old MNPS navigation specification to a more modern, Performance-Based Navigation (PBN) specification. This proposed rule would also correct and update the incorporation by reference of ICAO Annex 2 in the FAA's regulations.

This action relocates and updates the content of SFAR No. 108 to the newly created subpart N of part 91 in order to improve the safety of operating the Mitsubishi Heavy Industries (MHI) MU-2B series airplane. SFAR No. 108 will be eliminated from the Code of Federal Regulations on November 7, 2017, after which time all MU-2B operators must comply with this subpart. The FAA is relocating the training program from the SFAR No. 108 appendices to advisory material in order to allow the FAA to update policy while ensuring significant training adjustments still go through notice-and-comment rulemaking. The FAA is also correcting and updating several inaccurate maneuver profiles to reflect current FAA training philosophy and adding new FAA procedures not previously part of the MU-2B training under SFAR No. 108. This rule will require all MU-2B training programs to meet the requirements of this subpart and to be approved by the FAA to ensure safety is maintained. As a result of this action, operators, training providers, and safety officials will have more timely access to standardized, accurate training material.

This action amends the Appendix listing airports/locations with special operating restrictions in FAA's general operating and flight rules. Specifically, this action corrects the entry for Kansas City, MO (Kansas City International Airport) and updates the name of twelve (12) other airports listed in Appendix D, section 1. Additionally, this action updates the name of thirteen (13) airports listed in Appendix D, section 3, and the name of four (4) airports listed in Appendix D, section 4. The FAA is taking this action to correctly identify the airports listed in the appropriate special operating restrictions sections of the Appendix consistent with FAA aeronautical database information.

This action sets forth the Very High Frequency (VHF) Omnidirectional Range (VOR) Minimum Operational Network (MON) policy as proposed in the Proposed Provision of Navigation Services for the Next Generation Air Transportation System (NextGen) Transition to Performance-Based Navigation (PBN) notice of proposed policy published on December 15, 2011 (76 FR 77939). This document provides the discontinuance selection criteria and candidate list of VOR Navigational Aids (NAVAIDs) targeted for discontinuance as part of the VOR MON Implementation Program and United States (U.S.) National Airspace System (NAS) Efficient Streamline Services Initiative. Additionally, this policy addresses the regulatory processes the FAA plans to follow to discontinue VORs.

On October 27, 2015, the Federal Aviation Administration (FAA) published a final rule extending the prohibition against certain flight operations in the Simferopol (UKFV) and Dnipropetrovsk (UKDV) flight information regions (FIRs) by all United States (U.S.) air carriers; U.S. commercial operators; persons exercising the privileges of a U.S. airman certificate, except when such persons are operating a U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when such operators are foreign air carriers. The State Aviation Administration of Ukraine conducted and completed an airspace restructuring that altered the Simferopol (UKFV) and Dnipropetrovsk (UKDV) Flight Information Region (FIR) altitude structure specified in the final rule. To address the Ukraine airspace restructuring and provide additional clarity, this technical amendment specifically identifies the prohibited airspace in which Special Federal Aviation Regulation (SFAR) 113, applies, with inclusive altitudes and lateral limitations (latitude and longitude coordinates).

This action revises the FAA's requirements for an application to operate in Reduced Vertical Separation Minimum (RVSM) airspace and eliminates the burden and expense of developing, processing, and approving RVSM maintenance programs. As a result of this revision, an applicant to operate in RVSM airspace will no longer be required to develop and submit an RVSM maintenance program solely for the purpose of obtaining an RVSM authorization. Because of other, independent FAA airworthiness regulations, all aircraft operators remain required to maintain RVSM equipment in an airworthy condition.

The FAA is amending its regulations to allow the operation of small unmanned aircraft systems in the National Airspace System. These changes address the operation of unmanned aircraft systems and certification of their remote pilots. This rule will also prohibit model aircraft from endangering the safety of the National Airspace System.

This rulemaking would relieve burdens on pilots seeking to obtain aeronautical experience, training, and certification by increasing the allowed use of aviation training devices. These training devices have proven to be an effective, safe, and affordable means of obtaining pilot experience. This rulemaking also would address changing technologies by accommodating the use of technically advanced airplanes as an alternative to the use of older complex single engine airplanes for the commercial pilot training and testing requirements. Additionally, this rulemaking would broaden the opportunities for military instructors to obtain civilian ratings based on military experience, would expand opportunities for logging pilot time, and would remove a burden from sport pilot instructors by permitting them to serve as safety pilots. Finally, this rulemaking would include changes to some of the provisions established in an August 2009 final rule. These actions are necessary to bring the regulations in line with current needs and activities of the general aviation training community and pilots.

The FAA proposes to amend its airworthiness standards for normal, utility, acrobatic, and commuter category airplanes by removing current prescriptive design requirements and replacing them with performance-based airworthiness standards. The proposed standards would also replace the current weight and propulsion divisions in small airplane regulations with performance- and risk-based divisions for airplanes with a maximum seating capacity of 19 passengers or less and a maximum takeoff weight of 19,000 pounds or less. The proposed airworthiness standards are based on, and would maintain, the level of safety of the current small airplane regulations. Finally, the FAA proposes to adopt additional airworthiness standards to address certification for flight in icing conditions, enhanced stall characteristics, and minimum control speed to prevent departure from controlled flight for multiengine airplanes. This notice of proposed rulemaking addresses the Congressional mandate set forth in the Small Airplane Revitalization Act of 2013.

This action would establish a new noise standard for certain subsonic jet airplanes and subsonic transport category large airplanes. This noise standard, known as Stage 5, would apply to any person submitting an application for a new airplane type design with a maximum certificated takeoff weight of 121,254 pounds (55,000 kg) or more on or after December 31, 2017; or with maximum certificated takeoff weight of less than 121,254 pounds (55,000 kg) on or after December 31, 2020. This change would reduce the noise produced by new airplanes and harmonize the noise certification standards for those airplanes certificated in the United States with the new International Civil Aviation Organization noise standard in Annex 16, Chapter 14, effective July 14, 2014.

This action provides an alternative, streamlined and simple, web-based aircraft registration process for the registration of small unmanned aircraft, including small unmanned aircraft operated as model aircraft, to facilitate compliance with the statutory requirement that all aircraft register prior to operation. It also provides a simpler method for marking small unmanned aircraft that is more appropriate for these aircraft. This action responds to public comments received regarding the proposed registration process in the Operation and Certification of Small Unmanned Aircraft notice of proposed rulemaking, the request for information regarding unmanned aircraft system registration, and the recommendations from the Unmanned Aircraft System Registration Task Force. The Department encourages persons to participate in this rulemaking by submitting comments on or before the closing date for comments. The Department will consider all comments received before the closing date and make any necessary amendments as appropriate.

This action extends the prohibition against certain flight operations in the Simferopol (UKFV) and Dnipropetrovsk (UKDV) flight information regions (FIRs) by all United States (U.S.) air carriers; U.S. commercial operators; persons exercising the privileges of a U.S. airman certificate, except when such persons are operating a U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when such operators are foreign air carriers. This action also revises the FAA approval process for proposed operations authorized by other U.S. Government departments, agencies, and instrumentalities to clarify the FAA's expectations regarding requests for approval and revises the approval conditions and information about requests for exemptions to reflect the termination of statutory authorization for the FAA's premium war risk insurance program. This action also makes minor non-substantive corrections to the wording of the rule. The FAA finds this action to be necessary to address a continuing hazard to persons and aircraft engaged in such flight operations.

This proposed rulemaking would expand the temporary flight restriction provisions for launch, reentry, and amateur rocket operations and make such temporary flight restrictions applicable to all aircraft—including non-U.S. registered aircraft. The FAA also proposes revised language for consistency with other temporary flight restriction provisions and commercial space regulations and definitions. This proposed action would enhance safety in the affected airspace and would improve the readability of temporary flight restriction requirements.

This action reopens the comment period for the regulatory evaluation associated with the FAA's June 11, 2013 Notice of Proposed Rulemaking (NPRM), Revisions to Operational Requirements for the Use of Enhanced Flight Vision Systems (EFVS) and to Pilot Compartment View Requirements for Vision Systems. The regulatory evaluation associated with the NPRM was not posted to the docket prior to the close of the comment period. Therefore, the FAA is reopening the comment period to allow the public the opportunity to adequately analyze the full regulatory evaluation for the NPRM. The FAA will accept comments on the regulatory evaluation only; and not on the regulatory changes proposed in the NPRM.

With this document, the Federal Aviation Administration (FAA) cancels all previous agency policies pertaining to the carriage of passengers for compensation on Living History Flight Experience (LHFE) flights. This policy statement announces the end of FAA moratorium on new petitions for exemption, or amendments to exemptions from certain sections of Title 14, Code of Federal Regulations (14 CFR) for the purpose of carrying passengers for compensation or hire on LHFE Flights.

The Federal Aviation Administration is reminding operators of jet airplanes weighing 75,000 pounds or less that after December 31, 2015, operations in the contiguous United States may be conducted only with airplanes that comply with at least Stage 3 noise levels. Operators that fail to meet this requirement may be subject to civil penalties. Certain operations of airplanes not meeting Stage 3 may be conducted under special flight authorizations granted by the FAA on a case by case basis.

The FAA requests public comment on removal of the current transponder exception for gliders. This action responds to recommendations from members of Congress and the National Transportation Safety Board. The purpose of this action is to gather information to determine whether the current glider exception—from transponder equipment and use requirements—provides the appropriate level of safety in the National Airspace System. The FAA will use the information gathered from this action to determine whether additional transponder equipment and use requirements are necessary for gliders operating in the excepted areas.

This action would revise the FAA's requirements for an application to operate in Reduced Vertical Separation Minimum (RVSM) airspace. This proposal would eliminate the burden and expense of developing, processing, and approving RVSM maintenance programs. As a result of this proposed revision, an applicant to operate in RVSM airspace would no longer be required to develop and submit an RVSM maintenance program solely for the purpose of an RVSM authorization. Because of other, independent FAA airworthiness regulations, all aircraft operators would nevertheless continue to be required to maintain RVSM equipment in an airworthy condition.

The FAA is withdrawing a previously published direct final rule that would have prohibited fixed-wing special visual flight rules operations at Washington-Dulles International Airport. The FAA is withdrawing this action because it has received an adverse comment.

This action amends Special Federal Aviation Regulation (SFAR) No. 77, “Prohibition Against Certain Flights Within the Territory and Airspace of Iraq,” which prohibits certain flight operations in the territory and airspace of Iraq by all United States (U.S.) air carriers; U.S. commercial operators; persons exercising the privileges of a U.S. airman certificate, except when such persons are operating a U.S.-registered civil aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when such operators are foreign air carriers. On August 8, 2014, the FAA issued a Notice to Airmen (NOTAM) prohibiting flight operations in the ORBB FIR at all altitudes, subject to certain limited exceptions, due to the armed conflict in Iraq. This amendment to SFAR No. 77 incorporates the flight prohibition set forth in the August 8, 2014, NOTAM into the rule. The FAA is also revising the approval process for this SFAR for other U.S. Government departments, agencies, and instrumentalities, to align with the approval process established for other recently published flight prohibition SFARs. This final rule will remain in effect for two years.

This action prohibits fixed-wing special visual flight rules operations at Washington-Dulles International Airport. This action is necessary to support aviation safety and the efficient use of the navigable airspace by managing operations in the busy and complex airspace around the airport.

This action extends the prohibition of flight operations within the Tripoli (HLLL) Flight Information Region (FIR) by all: U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating a U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except operators of such aircraft that are foreign air carriers. The extension of the expiration date is necessary to address a potential hazard to persons and aircraft engaged in such flight operations. Additionally, the FAA is amending the prohibition to make clear that operations by sub-contractors under a U.S. Government department, agency, or instrumentality's contract, grant, or cooperative agreement may be included in an approval request and to remove an obsolete reference to paragraph 8 of United Nations Security Council Resolution (UNSCR) 1973. The FAA is also revising the approval conditions that will apply to operations authorized by other U.S. Government departments, agencies, and instrumentalities that are approved by the FAA, and the information about requests for exemption, to reflect the termination of statutory authorization for the FAA premium war risk insurance program.

The FAA is correcting a final rule technical amendment published on February 9, 2015 (80 FR 6899). In that final rule, which became effective on the date of publication, the FAA corrected errors in regulatory provisions addressing Automatic Dependent Surveillance-Broadcast Out equipment and use. The FAA inadvertently listed an incorrect Amendment Number for that final rule. This document corrects that error.

This policy statement updates and clarifies how the FAA determines when datalink communications must be recorded as a function of the cockpit voice recorder operational regulations. This policy update eliminates unneeded limitations in current policy, and restates the FAA's intent that the requirement function as a performance-based regulation.

The FAA is proposing to amend its regulations to adopt specific rules to allow the operation of small unmanned aircraft systems in the National Airspace System. These changes would address the operation of unmanned aircraft systems, certification of their operators, registration, and display of registration markings. The proposed rule would also find that airworthiness certification is not required for small unmanned aircraft system operations that would be subject to this proposed rule. Lastly, the proposed rule would prohibit model aircraft from endangering the safety of the National Airspace System.

The FAA is correcting a final rule published on May 28, 2010. In that rule, the FAA amended its regulations by adding equipage requirements and performance standards for Automatic Dependent Surveillance—Broadcast (ADS-B) Out avionics on aircraft operating in Classes A, B, and C airspace, as well as other specified classes of airspace within the U.S. National Airspace System (NAS). This document corrects errors in regulatory provisions addressing ADS-B Out equipment and use.

This action removes the prohibition against certain flights within the territory and airspace of Ethiopia contained in Special Federal Aviation Regulation (SFAR) No. 87 from the Code of Federal Regulations (CFR). The prohibition only applied to flight operations within the territory and airspace of Ethiopia north of 12 degrees north latitude conducted by United States (U.S.) air carriers or commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, unless that person was engaged in the operation of a U.S.-registered aircraft for a foreign air carrier; and operators using an aircraft registered in the United States, except where the operator of such aircraft was a foreign air carrier. The FAA has now determined that the safety and security situation that prompted the above flight prohibition has significantly improved, and that it is safe for U.S. civil flights to be operated within the entire territory and airspace of Ethiopia, subject to the approval of and in accordance with the conditions established by the appropriate authorities of Ethiopia.
