NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Coordinate with international regulatory agencies to inform them of the circumstances of the event involving Edelweiss Air flight EDW 565 and to encourage them to develop and adopt comprehensive standards and procedures regarding the introduction of new engine/oil combinations, including the inspection at appropriate intervals of those areas within the engine where testing or in-service experience has indicated porous carbon formation is likely and has the potential to result in a hazardous engine condition. This coordination effort should also ensure that sufficient data, including operational experience and engine hardware disassembly inspection findings, have been gathered and analyzed, with particular emphasis on airplanes approved for extended-range operation with two engines, to support continued operation of engine/oil combinations.
In plain language (FlightFinder summary)
The FAA is asked to coordinate with international regulatory agencies to share details of the Edelweiss Air flight EDW 565 event and encourage the development of standards for new engine/oil combinations, including inspections for porous carbon formation in areas where it could create a hazardous condition. The coordination should also ensure that enough operational and inspection data, particularly for twin-engine extended-range operations, is collected and analyzed to support the ongoing use of such combinations.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
