2011-27670 Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Model S-92A Helicopters Proposed Rule This document proposes adopting a new airworthiness directive (AD) for the Sikorsky Model S-92A helicopters. This proposal would require revising the Operating Limitations section of the Sikorsky Model S-92A Rotorcraft Flight Manual (RFM). This proposal is prompted by the manufacturer's analysis of engine data that revealed the data was inaccurate in dealing with available above specification engine power margin.
