This proposed AD would require replacing the support brackets of the 4005WX fire extinguisher bottle with reinforced support brackets, and replacing the strut assembly at the affected location, 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; Sikorsky Aircraft Corporation Model S-76A, S-76B, and S-76C Helicopters Modified by Supplemental Type Certificate SR09211RC
Document Number: 2021-01623
Type: Proposed Rule
Date: 2021-02-22
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 all Sikorsky Aircraft Corporation (Sikorsky) S-76 model helicopters with a certain life raft deployment system (LRDS) installed per Supplemental Type Certificate (STC) SR09211RC. The NPRM was prompted by an incident that occurred where the handle bent prior to the life raft deploying, and this prohibited the crew from successfully deploying and using the life raft. It was determined that the handle in this incident was not manufactured to the approved Type Design. The NPRM would have required removing and replacing the pilot or co-pilot life raft deployment handle (handle) located on the left side of the ``broom closet'' of the helicopter. Since issuance of the NPRM, the FAA determined that, based on a review of the design approval holder's records, all of the handles have been replaced. Accordingly, the NPRM is withdrawn.

Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2021-01609
Type: Proposed Rule
Date: 2021-02-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2020-09-14, which applies to certain Airbus SAS Model A350-941 and - 1041 airplanes. AD 2020-09-14 requires revising the existing airplane flight manual (AFM) to define a liquid-prohibited zone on the flight deck and provide procedures following liquid spillage on the center pedestal. AD 2020-09-14 also requires installing a removable integrated control panel (ICP) cover on the flight deck and further revising the AFM to include instructions for ICP cover use. Since the FAA issued AD 2020-09-14, a new, water-resistant ICP has been developed. This proposed AD would require installing a new, water-resistant ICP, which would allow removing the ICP protective cover and the AFM revisions, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
