14 CFR Chapter II, Subchapter B - PROCEDURAL REGULATIONS

We are superseding Airworthiness Directive (AD) 2012-12-05, which applied to all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. AD 2012-12-05 required repetitive inspections for cracking under the stop fittings and intercostal flanges and for cracking of the intercostal web, attachment clips, stringer splice channels, frame, reinforcement angle, shear web, frame outer chord and inner chord; a one-time inspection to detect missing fasteners; repetitive inspections of the cargo barrier net fitting for cracking; repetitive inspections for cracking of the stringer S-15L aft intercostal; and repair or corrective action if necessary. For certain airplanes, this AD adds new repetitive inspections of certain areas of the frame inner chord, and applicable on-condition actions. This AD was prompted by reports of additional cracking in locations not covered by the inspections in AD 2012-12-05. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain Fokker Services B.V. Model F28 Mark 0100 airplanes. This AD was prompted by a report that a jammed control cable prevented the full extension of the nose landing gear (LG). This AD requires a general visual inspection of the LG handle teleflex cable conduit connector for the presence of a grease nipple, a maintenance records check of affected airplanes, a detailed inspection for corrosion and damage of the LG handle teleflex cable, and corrective actions if necessary. This AD also requires revising the maintenance or inspection program, as applicable. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by several incidents of electrical shorting and sparks caused by de-icing fluid leaks between flight deck windshields and side windows. This AD requires water spray tests and general visual inspections for water in the flight deck compartment, and water removal and sealant application if necessary. We are issuing this AD to address the unsafe condition on these products.

This action establishes Class E airspace extending upward from 700 feet above the surface, at Rangely Airport, Rangely, CO, to accommodate new area navigation (RNAV) procedures at the airport. This action ensures the safety and management of instrument flight rules (IFR) operations within the National Airspace System.

We propose to adopt a new airworthiness directive (AD) for AgustaWestland S.p.A. (AgustaWestland) Model AW189 helicopters. This proposed AD would require inspecting the tail gearbox (TGB) fitting for a crack. This proposed AD is prompted by a report of a crack on a TGB fitting that was found during a scheduled inspection. The actions of this proposed AD are intended to prevent an unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, -500 series airplanes. This proposed AD was prompted by reports of cracking in certain flanges, and the adjacent web, of the wing outboard flap track at certain positions. This proposed AD would require an inspection to determine the part number of the wing outboard flap track assembly; repetitive inspections of each affected wing outboard flap track for discrepancies, and applicable on-condition actions; and repetitive overhaul of each wing outboard flap track. We are proposing this AD to address the unsafe condition on these products.

This action proposes to amend Class D airspace, Class E surface area airspace, and Class E airspace extending upward from 700 feet above the surface, at Aurora State Airport, Aurora, OR. After a biennial review the FAA found modification necessary to accommodate airspace redesign for the safety and management of instrument flight rules (IFR) operations at the airport. Additionally, an editorial change would be made removing the city associated with the airport name in the airspace designations. Also, this proposal would make an editorial change to the Class D airspace legal description replacing Airport/Facility Directory with the term Chart Supplement.

This action proposes to remove Class E airspace extending upward from 700 feet above the surface at Desert Rock Airport, Mercury, NV. This airspace is not required, as there are no instrument flight rules (IFR) operations at the airport.

This action proposes to remove Class E airspace extending upward from 1,200 feet above the surface at Sunol, CA. This airspace is wholly contained within the Sacramento en route airspace area and duplication is not necessary.

This action proposes to amend Class E surface area airspace and Class E airspace extending upward from 700 feet above the surface at Waimea-Kohala Airport, Kamuela, HI. The part-time Notice to Airmen (NOTAM) status would be removed from Class E surface area airspace, references to the Kamuela VOR/DME would be removed from all associated Class E airspace areas, and airspace boundaries would be modified to only that area necessary to contain instrument flight rules (IFR) operations at the airport. Airspace redesign is necessary as the FAA transitions from ground-based to satellite-based navigation for the safety and management of the national airspace system. Also, an editorial change would be made removing the airport name and replacing it with the city in the airspace designators for the above airspace areas.

We are adopting a new airworthiness directive (AD) for Pacific Aerospace Limited Model 750XL airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as abrasion damage of components or wiring behind the instrument panel. We are issuing this AD to require actions to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for Pacific Aerospace Limited Model 750XL airplanes.

This AD requires initial and repetitive visual inspection and fluorescent-penetrant inspection (FPI) of the main propeller shaft. This AD was prompted by the failure of a main propeller shaft. We are issuing this AD to address the unsafe condition on these products.

The FAA is amending four high altitude Area Navigation (RNAV) Q-routes (Q-140, Q-818, Q-935, and Q-947) that cross the United States (U.S.)/Canada border in the north central U.S. This action updates the latitude/longitude coordinates for three Canadian waypoints listed in the Q-route descriptions contained in the FAA aeronautical database to match the Canadian aeronautical database source information.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
