The FAA has extended the deadline for comments relating to its ETOPS (Extended Twin-Engine Operations) Notice of Proposed Rulemaking: Docket Number 6717 an additional 60 days. The new deadline is March 15 and should be published in the January 6 Federal Register. Under the FAA’s proposed rule aircraft operated under FAR Part 135 would be required to remain within 180 minutes of an airport unless approved for extended operations. Aircraft operated under FAR Part 121 would have a 207 minute limitation. Although most comments are in favor of the proposed limitations, a minority argue that loss of one engine could compromise other critical aircraft systems that would jeopardize the aircraft’s ability to divert to a suitable alternate airport on only one engine.
