February 22, 2021 – Federal Register Recent Federal Regulation Documents

The FAA is withdrawing a notice of proposed rulemaking (NPRM) and supplemental notice of proposed rulemaking (SNPRM) that proposed to supersede airworthiness directive (AD) 72-14-08 R1 for Cessna Aircraft Company (now Textron Aviation Inc.) Models 310, 320, 401, 402, 411, and 421 airplanes. AD 72-14-08 R1 requires repetitively inspecting the fuel and oil flexible hose lines for leakage or evidence of any damaged or deteriorated hose assembly on the above-referenced airplanes and replacing any discrepant part. Since issuance of the SNPRM, the FAA has not received any reports of fuel and oil flexible hose lines that leak or are damaged and has determined that the repetitive inspections required by AD 72-14-08 R1 address the unsafe condition. Accordingly, the NPRM and SNPRM are withdrawn.

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 Accordingly, the NPRM is withdrawn.

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.

This document contains corrections to the final regulations (Treasury Decision 9935) that were published in the Federal Register on Wednesday, December 2, 2020.
