Federal Aviation Administration December 15, 2020 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2012-04-15, which applies to all Pratt & Whitney (PW) JT9D-3A, JT9D-7, JT9D-7A, JT9D-7AH, JT9D-7F, JT9D-7H, JT9D-7J, JT9D-20, JT9D-20J, JT9D- 59A, JT9D-70A, JT9D-7Q, JT9D-7Q3, JT9D-7R4D, JT9D-7R4D1, JT9D-7R4E, JT9D-7R4E1, JT9D-7R4E4, JT9D-7R4G2, and JT9D-7R4H1 (JT9D) model turbofan engines. AD 2012-04-15 requires revisions to the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA) to include required enhanced inspection of selected critical life-limited parts at each piece-part opportunity. AD 2012-04-15 also requires additional revisions to the JT9D model engines ALS of the manufacturer's ICA. Since the FAA issued AD 2012-04- 15, PW notified the FAA that revisions to the mandatory inspections contained within the ALS of the manufacturer's ICA were necessary. This proposed AD would revise the required inspections of selected critical life-limited parts specified in the ALS of the manufacturer's ICA and, for air carriers, to the existing continuous airworthiness air carrier maintenance program (CAMP). The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, and AS350D helicopters; Model AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters; and Model EC130B4 and EC130T2 helicopters. This proposed AD was prompted by a report of failed main rotor hub-to-mast attachment screws. This proposed AD would require determining whether the helicopter has been operated in a severe environment since the last inspection of the main rotor hub-to-mast attachment screws, an inspection of the main rotor hub-to-mast attachment screws if the helicopter has been operated in a severe environment, and replacement of the main rotor hub-to-mast attachment screws if necessary, as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.

This action establishes Class E airspace extending upward from 700 feet above the surface for New Garden Airport, Toughkenamon, PA, to accommodate new instrument procedures designed for the airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.
