# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Proposed rule; withdrawal.

# SUMMARY:

                        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                               ( print page 10505)                            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 Accordingly, the NPRM is withdrawn.                    

# DATES:

The FAA is withdrawing the proposed rule published March 1, 2011 (76 FR 11174), as of February 22, 2021.

# SUPPLEMENTARY INFORMATION:

## Discussion

                    The FAA has issued an NPRM that proposed to amend 14 CFR part 39 by adding an AD that would apply to the specified products. The NPRM was published in the                     **Federal Register**                     on March 1, 2011 (76 FR 11174). 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 proposed to require removing and replacing the pilot or co-pilot handle located on the left side of the “broom closet” of the helicopter. The proposed actions were intended to address bending of the handle, which could result in failure of the life raft to deploy. This failure could lead to loss of access to the life raft after an emergency ditching on water.

## Actions Since the NPRM Was Issued

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, which addresses the identified unsafe condition. Therefore, the FAA determined that AD action is not appropriate.

Withdrawal of the NPRM constitutes only such action and does not preclude the FAA from further rulemaking on this issue, nor does it commit the FAA to any course of action in the future.

## Comments

The FAA gave the public the opportunity to comment on the NPRM. The FAA received no comments on the NPRM or on the determination of the cost to the public.

## FAA's Conclusions

Upon further consideration, the FAA determined that the NPRM is unnecessary. Accordingly, the NPRM is withdrawn.

## Regulatory Findings

Since this action only withdraws an NPRM, it is neither a proposed nor a final rule. This action therefore is not covered under Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979).
