Agency: Federal Aviation Administration, Department of Transportation
The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to supersede Airworthiness Directive (AD) AD 2002-20-01, which applies to certain Model HH-1K, TH-1F, TH-1L, UH-1A, UH-1B, UH- 1E, UH-1F, UH-1H, UH-1L, and UH-1P helicopters; and Southwest Florida Aviation Model SW204, SW204HP, SW205, and SW205A-1 helicopters, manufactured by Bell Helicopter Textron, Inc. (BHTI) for the Armed Forces of the United States. The NPRM would have required removing certain serial-numbered tension-torsion (TT) straps from service, reducing the retirement life for other TT straps, and establishing a retirement life in terms of calendar time in addition to hours time-in- service (TIS) for certain other affected TT straps. The NPRM also would have added two model helicopters to the applicability of the AD. The NPRM was prompted by fatigue cracking in certain TT straps that have stainless steel filament windings and a determination that corrosion damage, which is related to calendar time, necessitated a calendar time retirement life for certain TT straps in addition to the retirement life based on hours TIS. The NPRM was also prompted by fatigue cracking in other TT straps with encased thin stainless steel plates. Since issuance of the NPRM, the FAA has re-reviewed the available information and determined that the totality of the available information does not support issuance of a final rule. Accordingly, the NPRM is withdrawn.
Airworthiness Directives; Airbus SAS Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters. This proposed AD was prompted by reduced life limits being established for certain part-numbered tail rotor (TR) blades. This proposed AD would require determining the total hours time-in-service (TIS) of certain part-numbered TR blades, establishing a life limit for certain part-numbered TR blades, removing from service any TR blade that has reached or exceeded its life limit, creating a component history card, re-identifying certain part-numbered TR blades, and removing any TR blade from service before reaching its retirement life. This proposed AD would also prohibit installing certain TR blades on certain model helicopters. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bell Textron Inc. (Type Certificate Previously Held by Bell Helicopter Textron Inc.) Helicopters
Document Number: 2021-20408
Type: Rule
Date: 2021-09-23
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Inc. (type certificate previously held by Bell Helicopter Textron Inc.) Model 205B helicopters. This AD was prompted by a notification of certain parts needing a life limit. This AD requires determining the total hours time-in-service (TIS) of certain part-numbered main rotor grip assemblies (grip assemblies), establishing a life limit for certain part-numbered grip assemblies, removing from service any grip assembly that has reached or exceeded its retirement life, creating a component history card, and removing any grip assembly from service before reaching its retirement life. This AD also prohibits installing certain grip assemblies unless the life limit was established in accordance with this AD. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
Document Number: 2021-20407
Type: Proposed Rule
Date: 2021-09-23
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS355NP helicopters. This proposed AD was prompted by a report of mechanical deformation found on the protective cover (also referred to as switch guard) of the ``SHEAR'' control pushbutton installed on a co-pilot collective stick of a Model EC225LP helicopter, caused by incorrect handling; due to having an identical design switch guard installed on the pilot collective stick, Model AS355NP helicopters are also affected. This proposed AD would require replacement of the protective cover of the ``SHEAR'' control pushbutton, and re-identification of the pilot collective stick, 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; Airbus SAS Airplanes
Document Number: 2021-20405
Type: Proposed Rule
Date: 2021-09-23
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by reports of slat transmission jams caused by frozen slat geared rotary actuators (SGRA) at slat 5 track 12. This proposed AD would require repetitive water drainage and plug cleaning of the left- and right-hand SGRA having a certain part number installed on slat 5 track 12 with certain functional item numbers, 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; Gulfstream Aerospace LP Airplanes; Correction
Document Number: 2021-20404
Type: Rule
Date: 2021-09-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to certain Gulfstream Aerospace LP Model Gulfstream G280 airplanes. As published, the document number of the Civil Aviation Authority of Israel (CAAI) AD specified in the preamble and regulatory text is incorrect. This document corrects that error. In all other respects, the original document remains the same.
Airworthiness Directives; Pratt & Whitney Turbofan Engines
Document Number: 2021-20365
Type: Rule
Date: 2021-09-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all Pratt & Whitney PW1500G and PW1900G series turbofan engines with a certain high-pressure turbine (HPT) 1st-stage hub or HPT rotor 1st- stage blade retaining plate installed. This AD was prompted by a report from the manufacturer who determined that the HPT 1st-stage hub and HPT rotor 1st-stage blade retaining plate fail to meet the published life- cycle limits for each part. This AD requires removal and replacement of the HPT 1st-stage hub and HPT rotor 1st-stage blade retaining plate prior to reaching certain cycle limits. The FAA is issuing this AD to address the unsafe condition on these products.
