Airworthiness Standards; New Rotorcraft 30-Second/2-Minute One-Engine- Inoperative Power Ratings; Final Rule DEPARTMENT OF TRANSPORTATION

This rule adopts new and revised airworthiness standards by incorporating optional one-engine-inoperative (OEI) power ratings for multiengine, turbine-powered rotorcraft. These amendments result from a petition for rulemaking from Aerospace Industries Association of America (AIA) and the recognition by both government and industry that additional OEI power rating standards are needed. These amendments enhance rotorcraft safety after an engine failure or precautionary shutdown by providing higher OEI power, when necessary. These amendments also assure that the drive system will maintain its structural integrity and allow continued safe flight while operating at the new OEI power ratings with the operable engine(s).
