AD FAA-2009-0559

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.
