Federal Aviation Administration July 28, 2021 – Federal Register Recent Federal Regulation Documents

This action amends Class E surface area and Class E airspace extending upward from 700 feet above the surface at Hancock County-Bar Harbor Airport, Bar Harbor, ME. This action would also update the geographic coordinates of the airport to coincide with the FAA's database. In addition, this action also establishes Class E airspace extending upward from 700 feet above the surface for Bar Harbor Heliport, Bar Harbor, ME. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

The FAA is publishing and requesting comments on this IRFA for the previously published notice of proposed rulemaking (NPRM), Project Identifier AD-2020-01314-P, applicable to Hamilton Sundstrand Corporation 54H model propellers with a 54H60 model propeller hub installed. That NPRM proposed to supersede Airworthiness Directive (AD) 2020-12-07, which applies to certain Hamilton Sundstrand Corporation (Hamilton Sundstrand) 54H model propellers.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL airplanes. This proposed AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as chafing damage in the port wing skin caused by the fuel system finger filters. This proposed AD would require inspecting the wing internal skin for chafing and taking any necessary corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation (Gulfstream) Models G-IV and GIV-X airplanes. The NPRM was prompted by reports of disbonding and surface cracking of the composite aft pressure bulkhead. The NPRM proposed to require inspecting the forward and aft surfaces of the pressure bulkhead composite panels for damage and repairing any damage found. Since issuance of the NPRM, the FAA has determined that there is not an unsafe condition. Accordingly, the NPRM is withdrawn.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW169 helicopters. This proposed AD was prompted by a report of a broken adjustable device that is part of the pilot and co-pilot yaw pedal assemblies. This proposed AD would require modification of the pilot and co-pilot yaw pedal assemblies, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). 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 SAS Model A330-200, -200 Freighter, -300 and -900 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. This proposed AD was prompted by a report that during the frame of flight test clearance process, a detailed analysis of air data reference (ADR) failure scenarios led to the identification that compliance requirements for loads and handling qualities throughout the flight envelope could be impaired in case of dispatch with one ADR inoperative (master minimum equipment list (MMEL) item 34-10-01) during the maximum interval allowed by the current MMEL. This proposed AD would require revising the operator's existing FAA-approved minimum equipment list (MEL) for the air data/inertial reference system, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
