Final rule; OMB approval of information collection.

The rule published on December 1, 2011, and became effective on January 30, 2012. However, at the time of publication, the new information collection requirements imposed by 14 CFR 27.573 and 29.573 lacked OMB approval. This document announces receipt of OMB's June 28, 2012 approval.

14 CFR Parts 27 and 29

Summary

This document notifies the public of the Office of Management and Budget's (OMB's) approval of the information collection requirement contained in the FAA's final rule, “Damage Tolerance and Fatigue Evaluation of Composite Rotorcraft Structures,” which was published on December 1, 2011.

Final special conditions; request for comments.

The effective date of these special conditions is July 30, 2012. We must receive your comments by September 27, 2012.

14 CFR Part 27

Summary

These special conditions are issued for the Eurocopter France Model EC130T2 helicopter. This model helicopter will have the novel or unusual design feature of a 30-minute power rating, generally intended to be used for hovering at increased power for search and rescue missions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

Final rule; correction.

This correction is effective February 1, 2012. The “Composite Rotorcraft Structures” final rule becomes effective January 30, 2012. The “Metallic Structures” final rule becomes effective January 31, 2012.

14 CFR Parts 27 and 29

Summary

The FAA is correcting two final rules, “Damage Tolerance and Fatigue Evaluation for Composite Rotorcraft Structures” (76 FR 74655), published December 1, 2011, and “Damage Tolerance and Fatigue Evaluation for Metallic Structures” (76 FR 75435), published December 2, 2011. In the “Composite Rotorcraft Structures” rule, the FAA amended its regulations to require evaluation of fatigue and residual static strength of composite rotorcraft structures using a damage tolerance evaluation, or a fatigue evaluation if the applicant establishes that a damage tolerance evaluation is impractical. In the “Metallic Structures” rule, the FAA amended its regulations to address advances in structural fatigue substantiation technology for metallic structures to provide an increased level of safety by avoiding or reducing the likelihood of the catastrophic fatigue failure of a metallic structure. This document corrects errors in the preamble of those two documents by adding a statement advising that affected parties do not need to comply with the information collection requirements until the Office of Management and Budget (OMB) approves the collections.

Request for comments.

Send your comments to reach us on or before May 23, 2013.

14 CFR Parts 27 and 29

Summary

The Federal Aviation Administration (FAA) is requesting comments and information on the public's interest in restructuring the rotorcraft airworthiness standards of normal category rotorcraft and transport category rotorcraft. Specifically, the agency is seeking comments on whether to change the existing applicability standards for maximum weight and number of passenger seats for either or both types of rotorcraft, or whether to consider other approaches for determining applicability. The FAA is soliciting public input because of some rotorcraft community interest in increasing the 7,000 pound maximum weight limit for the modern normal category rotorcraft and because there may be recommendations for new approaches to make the rotorcraft airworthiness standards more efficient and adaptable to future technology. This action is part of an effort to develop recommendations for possible FAA rulemaking action.
