FAA Proposes OEI Standard ‘Harmonization’

 - May 10, 2007, 12:13 PM

The FAA has proposed a number of revisions to the rotorcraft one-engine-inoperative (OEI) rating definition and type certification standards to align the regulations with those in use by the European Aviation Safety Agency (EASA) and Transport Canada Civil Aviation. According to the FAA, the opposing standards cause a “hardship” to applicants seeking dual certification “in the form of additional costs and delays.” Among the proposed changes is an additional reference to “engine shutdown” in the definition of OEI power ratings, which currently refers only to “engine failure.” The FAA estimates that eight engine models and around 100 helicopters will be affected by the proposed changes, at an estimated fleet-wide cost of $619,000 over the next 20 years. The agency has not estimated the cost savings of such a proposal but did note that there would be a “large potential harmonization savings.” Comments are due August 2.
