Federal Aviation Administration September 9, 2021 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2021-19460
Type: Proposed Rule
Date: 2021-09-09
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2020-21-17, which applies to all The Boeing Company Model 757 airplanes. AD 2020-21-17 requires repetitive inspections for skin cracking and shim migration at the upper link drag fittings, diagonal brace cracking, and fastener looseness; and applicable on-condition actions. Since the FAA issued AD 2020-21-17, a determination has been made that the compliance times for certain groups are not adequate. This proposed AD would retain the requirements of AD 2020-21-17 with reduced compliance times for certain airplane groups. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Gulfstream Aerospace LP Airplanes
Document Number: 2021-19389
Type: Rule
Date: 2021-09-09
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream G280 airplanes. This AD was prompted by a report that during full-scale fatigue testing, a crack was found in the area of the attachment of the wing rib 0 to the front spar. This AD requires non-destructive testing on the forward (front) spar vertical stiffener and rib 0 for any cracking, installation of a doubler to the forward (front) spar and rib 0 attachment, and repair if necessary, as specified in a Civil Aviation Authority of Israel (CAAI) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2021-19355
Type: Proposed Rule
Date: 2021-09-09
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) that would have applied to certain The Boeing Company Model 787-8, 787-9, and 787- 10 airplanes. The NPRM was prompted by reports that very high frequency (VHF) radio frequencies transfer between the active and standby windows of the tuning control panel (TCP) without flightcrew input. The NPRM would have required updating the TCP operational software (OPS) and performing a software configuration check. Since issuance of the NPRM, the FAA determined that the TCP OPS version specified in the NPRM does not correct the unsafe condition. The FAA intends to propose new rulemaking to require updated software. Accordingly, the NPRM is withdrawn.
Proposed Amendment of United States Area Navigation Route Q-73 in the Vicinity of Twentynine Palms, CA
Document Number: 2021-19321
Type: Proposed Rule
Date: 2021-09-09
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to amend United States Area Navigation (RNAV) route Q-73 due to the creation of Special Activity Airspace (SAA) (Bristol Air Traffic Control Assigned Airspace (ATCAA)) in the vicinity of Twentynine Palms, CA.
Airworthiness Directives; Embraer S.A. (Type Certificate Previously Held by Empresa Brasileira de Aeronáutica S.A.) Airplanes
Document Number: 2021-19304
Type: Proposed Rule
Date: 2021-09-09
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2020-12-08, which applies to all Embraer S.A. Model EMB-505 airplanes. AD 2020-12-08 requires inspections of the mass-balance weights of the elevators, ailerons, and rudder (flight control surfaces) and their attachment parts, and corrective actions if necessary, and revising the airworthiness limitation section of the maintenance manual or instructions for continued airworthiness to incorporate new airworthiness limitations. Since AD 2020-12-08 was issued, the FAA has determined that new applicable airplane serial numbers and new criteria for the replacement of affected parts must be required in order to address the unsafe condition. This proposed AD would retain the actions required by AD 2020-12-08 and would require, for certain airplanes, cleaning and weighing certain mass-balances and installation or replacement, as applicable; and for certain other mass-balances for certain airplanes, replacement of those mass-balances. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; B-N Group Ltd. Airplanes
Document Number: 2021-19302
Type: Rule
Date: 2021-09-09
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for B-N Group Ltd. Models BN-2, BN-2A, BN-2A-2, BN-2A-3, BN-2A-6, BN-2A-8, BN- 2A-9, BN-2A-20, BN-2A-21, BN-2A-26, BN-2A-27, BN-2B-20, BN-2B-21, BN- 2B-26, BN-2B-27, BN-2T, and BN-2T-4R airplanes. This 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 failure of the rudder final drive rod because of cracks in the region of the taper pins. This AD requires repetitively inspecting the rudder final drive rod assembly and replacing the rudder final drive assembly, if necessary. The FAA is issuing this AD to address the unsafe condition on these products.

Date: 2021-09-09
Agency: Federal Aviation Administration, Department of Transportation
