Proposal Would Align Standards With EASA, Transport Canada
Guidelines
The Federal Aviation Administration (FAA) is proposing to amend
One-Engine-Inoperative (OEI) rating definitions and type
certification standards for 30-second OEI, 2-minute OEI, and
30-minute OEI ratings for rotorcraft turbine engines. If
adopted, the proposed rule would better align FAA certification
standards 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.
The One-Engine-Inoperative (OEI) rating powers provide
rotorcraft with higher than takeoff and maximum continuous rating
powers during takeoff, cruise, and landing when one or more engines
of a multi-engine rotorcraft fails or is shutdown. These OEI rating
powers enable the rotorcraft to continue safe flight until it
reaches a suitable landing site.
Part 33 prescribes airworthiness standards for 30-second OEI,
2-minute OEI, 21.2-minute OEI, 30-minute OEI, and other OEI ratings
for the issuance of type certificates for rotorcraft turbine
engines. All OEI ratings are optional ratings, that engine
manufacturers may select from those specified under section
33.7.
The FAA will accept comments on the NPRM, available in full at
the FMI link below, until August 2.
