PRODUCT: Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters.
SUBJECT: Airworthiness Directive 2012-08-01
ACTION: Final Rule

SUMMARY: This AD was prompted by the manufacturer's analysis of engine data that revealed the data was inaccurate in dealing with available above specification engine power margin. This AD requires revising the Operating Limitations section of the Sikorsky Model S-92A Rotorcraft Flight Manual (RFM). The actions are intended to prevent the use of inaccurate engine performance data in calculating maximum gross weight by revising the Operating Limitations section of the RFM.

DATES: This AD is effective May 24, 2012.
