Airworthiness Directives; Sikorsky

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Proposed rule; withdrawal. 

SUMMARY: The FAA is withdrawing a 

notice of proposed rulemaking (NPRM). 

The NPRM proposed a new 

airworthiness directive (AD) for 

Sikorsky Model S–92A helicopters. The 

proposed action would have required 

revising the Limitations section of the 

Rotorcraft Flight Manual (RFM) to 

clarify that the Model S–92A helicopter 

was certificated as a transport category 

rotorcraft in both Categories A and B 

with different operating limitations for 

each category and must be operated 

accordingly. Since we issued the NPRM, 

we have determined that operating the 

helicopter in Category B with 10 or 

more passenger seats is not an unsafe 

condition but an inconsistency with 14 

CFR 29.1(c). Accordingly, we withdraw 

the proposed rule. 

DATES: As of March 14, 2016, the 

proposed rule to amend 14 CFR part 39 

published June 19, 2009 (74 FR 29148) 

is withdrawn.

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 to 

add a new AD (74 FR 29148, June 19, 

2009) for Sikorsky Model S–92A 

helicopters. The NPRM proposed to 

require revising the Limitations section 

of the RFM by clarifying that the Model 

S–92A helicopter was certificated as a 

transport category rotorcraft in both 

Categories A and B with different 

operating limitations for each category 

and must be operated accordingly. 

When the Model S–92A is configured 

with 10 or more passenger seats, it is a 

Category A helicopter, and operators 

must follow the limitations for Category 

A. When it is configured with 9 or fewer 

passenger seats, it may be considered a 

Category B helicopter, and operators 

may follow the less stringent Category B 

limitations. At the time the NPRM was 

published, the limitation language in 

the RFM did not make a clear 

distinction between Category A and 

Category B based on the seating 

configuration. The proposed actions 

were intended to prevent operating 

under less stringent requirements. 

Actions Since NPRM (74 FR 29148, 

June 19, 2009) Was Issued 

Since we issued the NPRM (74 FR 

29148, June 19, 2009), one commenter 

noted the proposed AD misinterprets 

certification rules as operational rules. 

We considered the comment and reevaluated the details that went into the 

determination of the unsafe condition 

for this concern. We determined that 

operating the helicopter in Category B 

with 10 or more passengers is not an 

unsafe condition, and the associated 

level of risk does not warrant AD action. 

Rather, this was an inconsistency with 

14 CFR 29.1(c). Sikorsky has since 

revised the RFM to clarify that a 

helicopter configured with a maximum 

of 19 passenger seats must be operated 

as a Category A but if configured with 

9 or fewer passenger seats may be 

operated as a Category B. This action 

mitigates the inconsistency with 14 CFR 

29.1(c). 

Withdrawal of the NPRM constitutes 

only such action and does not preclude 

the agency from issuing another notice 

in the future nor does it commit the 

agency to any course of action in the 

future. 

Since this action only withdraws an 

NPRM, it is neither a proposed nor a 

final rule; therefore, it is not covered 

under Executive Order 12866, the 

Regulatory Flexibility Act, or DOT 

Regulatory Policies and Procedures (44 

FR 11034, February 26, 1979).

Accordingly, the notice of proposed

is withdrawn.
