FAA To Align OEI Rules with EASA

The FAA is proposing to amend one engine inoperative (OEI) rating definitions. These relatively small changes would affect type certification standards for 30-second OEI, two-minute OEI and 30-minute OEI ratings. For example, the changes would address engine shutdown as well as engine failure. The proposed rule would yield harmonization with the European Aviation Safety Agency’s (EASA) certification specifications for engines. Similarly, FAA rules would be more in line with Transport Canada’s proposed requirements. Comments are due by August 2, and the docket number is FAA-2007-27899.
