Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
Document Number: 2021-05583
Type: Rule
Date: 2021-03-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by a report that threaded fuel couplings were incorrectly installed at final assembly and in service. This AD requires repetitive functional tests of the auxiliary power unit (APU) fuel feed line shroud, a general visual inspection of the APU fuel feed line shroud for any loose couplings; and tightening any loose couplings, which would terminate the repetitive functional tests. The FAA is issuing this AD to address the unsafe condition on these products.

Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for Bell Textron Canada Limited (type certificate previously held by Bell Helicopter Textron Canada Limited) (Bell) Model 505 helicopters. This proposed AD was prompted by the discovery of a gap between the transmission restraint assembly aft attachment hardware lower washer and mating airframe truss assembly (truss assembly) clevis lower lug. This proposed AD would require inspecting the transmission restraint aft attachment hardware installation for a gap and corrective action depending on the inspection results. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters (Type Certificate Previously Held by Eurocopter France) Helicopters
Document Number: 2021-05426
Type: Proposed Rule
Date: 2021-03-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters (Type Certificate previously held by Eurocopter France) Model AS350B3 and EC130T2 helicopters. This proposed AD was prompted by a report of failure of an engine digital electronic control unit (DECU). This proposed AD would require revising the existing Rotorcraft Flight Manual (RFM) for your helicopter. This proposed AD would also allow the option of modifying the electronic engine control unit (EECU) as terminating action for the RFM revision. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2021-05395
Type: Proposed Rule
Date: 2021-03-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-200, A330-200 Freighter, A330-300, A340- 200, and A340-300 series airplanes. This proposed AD was prompted by a report that the auxiliary power unit (APU) aft fuel pump printed circuit board (PCB) varnish had deteriorated; the varnish is one of the layers of protection against development of an ignition source. 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.
Airworthiness Directives; De Havilland Aircraft of Canada Limited (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
