Airworthiness Directives; Pacific Aerospace Limited Airplanes
Document Number: 2021-15954
Type: Proposed Rule
Date: 2021-07-28
Agency: Federal Aviation Administration, Department of Transportation
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.
Airworthiness Directives; Learjet Inc.
Document Number: 2021-15953
Type: Proposed Rule
Date: 2021-07-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Learjet Inc. (Learjet) Model 45 airplanes. This proposed AD was prompted by reports of corrosion found on the upper surface of the lower center wing mid spar splice plate. This proposed AD would require repetitively inspecting the center wing area for corrosion and deterioration of protective treatments, removing any corrosion, and treating any deteriorated areas. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes
Document Number: 2021-15952
Type: Proposed Rule
Date: 2021-07-28
Agency: Federal Aviation Administration, Department of Transportation
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 Accordingly, the NPRM is withdrawn.
Airworthiness Directives; Pacific Aerospace Limited Airplanes
Document Number: 2021-15951
Type: Proposed Rule
Date: 2021-07-28
Agency: Federal Aviation Administration, Department of Transportation
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 identifies the unsafe condition as insufficient clearance between the engine mount, the Beta control rod, and the inter-turbine temperature (ITT) sensing probe that could lead to chafing damage. This proposed AD would require inspecting the engine mount, the temperature probe, and the reversing cable for damage, and taking any necessary corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Leonardo S.p.a. Helicopters
Document Number: 2021-15950
Type: Proposed Rule
Date: 2021-07-28
Agency: Federal Aviation Administration, Department of Transportation
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.
Airworthiness Directives; Pratt & Whitney Turbofan Engines
Document Number: 2021-15947
Type: Rule
Date: 2021-07-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW2037, PW2037M, PW2040, and F117-PW-100 model turbofan engines. This AD was prompted by a report of an uncontained engine failure resulting from cracks in the knife edge of the high- pressure turbine (HPT) 2nd-stage air seal assembly. This AD requires fluorescent penetrant inspections (FPIs) and visual inspections of the HPT 2nd-stage air seal assembly and, depending on the results of the inspections, replacement of the HPT 2nd-stage air seal assembly with a part eligible for installation. This AD also requires replacement of the affected HPT 2nd-stage air seal assembly, depending on the engine model, at either the next engine shop visit or the next piece-part opportunity. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2021-15942
Type: Proposed Rule
Date: 2021-07-28
Agency: Federal Aviation Administration, Department of Transportation
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.
