Federal Aviation Administration May 4, 2007 – Federal Register Recent Federal Regulation Documents

Airworthiness Standards: Rotorcraft Turbine Engines One-Engine-Inoperative (OEI) Ratings, Type Certification Standards
Document Number: E7-7943
Type: Proposed Rule
Date: 2007-05-04
Agency: Federal Aviation Administration, Department of Transportation
The Federal Aviation Administration (FAA) is proposing to amend OEI rating definitions and type certification standards for 30- second OEI, 2-minute OEI, and 30-minute OEI ratings for rotorcraft turbine engines. This proposed rule, if adopted, would revise the ratings' standards to reflect recent analyses of the ratings' usage and lessons learned from completed engine certifications and service experience. This proposal harmonizes FAA type certification standards for these ratings with the requirements of the European Aviation Safety Agency in the Certification Specifications for Engines (CS-E) and with proposed requirements for Transport Canada Civil Aviation. If adopted, the proposed changes would establish nearly uniform certification standards for ratings for rotorcraft turbine engines certificated in the United States under part 33 and in European countries under CS-E, thus simplifying airworthiness approvals for import and export.
