Airworthiness Directives; CFM International, S.A. Turbofan Engines
Document Number: 2021-05591
Type: Proposed Rule
Date: 2021-03-23
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) LEAP-1A23, LEAP-1A24, LEAP- 1A24E1, LEAP-1A26, LEAP-1A26CJ, LEAP-1A26E1, LEAP-1A29, LEAP-1A29CJ, LEAP-1A30, LEAP-1A32, LEAP-1A33, LEAP-1A33B2, and LEAP-1A35A model turbofan engines.

Airworthiness Directives; Piper Aircraft, Inc. Airplanes
Document Number: 2021-05584
Type: Proposed Rule
Date: 2021-03-23
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 79- 01-03, which applies to certain Piper Aircraft, Inc. (Piper) Model PA- 36-285 airplanes, and AD 83-20-03, which applies to Piper Models PA-36- 285, PA-36-300, and PA-36-375 airplanes. AD 79-01-03 requires repetitive inspections of the spar carry through assembly until it is replaced with a different part numbered spar carry through assembly. AD 83-20-03 establishes life limits for the wing spar structural components. Since the FAA issued AD 79-01-03 and AD 83-20-03, the FAA identified inspection and life limit requirements that were inadvertently omitted from those ADs. This proposed AD would retain the requirements in AD 79-01-03 and AD 83-20-03 and require the spar carry through assembly inspection from AD 79-01-03 for additional airplanes and add life limits for certain wing structural components previously omitted from AD 83-20-03 for certain serial numbered airplanes. The FAA is proposing this AD to address the unsafe condition on these products.

This proposed AD would require replacing each affected APU aft fuel pump, 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.
Airworthiness Directives; Airbus Helicopters
Document Number: 2021-05355
Type: Proposed Rule
Date: 2021-03-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising a notice of proposed rulemaking (NPRM) that applied to certain Airbus Helicopters Model AS-365N2, AS 365 N3, SA-365N, and SA-365N1 helicopters. The NPRM proposed to require either replacing the main gearbox (MGB) or as an alternative, replacing the epicyclic reduction gear module for certain serial numbered planet gear assemblies installed on the MGB. The NPRM also proposed to require inspecting the MGB magnetic plugs and oil filter for particles and, depending on the outcome of the inspection, further inspections and replacing certain parts. The NPRM was prompted by the failure of an MGB second stage planet gear. This action revises the NPRM by expanding the applicability to include all Airbus Helicopters Model AS-365N2, AS 365 N3, SA-365N, and SA-365N1 helicopters. Since these actions impose an additional burden over that proposed in the NPRM, the FAA is reopening the comment period to allow the public the chance to comment on these proposed changes.
