NTSB Safety Recommendation — Aviation
Recommendation text
ISSUE A MAINTENANCE ALERT BULLETIN DIRECTING FAA MAINTENANCE INSPECTORS TO CONTACT THEIR ASSIGNED CARRIERS AND ADVISE THEM TO IMMEDIATELY DISCONTINUE THE PRATICE OF LOWERING AND RAISING THE PYLON WITH THE ENGINE STILL ATTACHED. CARRIERS SHOULD ADHERE TO THE PROCEDURE RECOMMENDED BY THE DOUGLAS AIRCRAFT COMPANY SERVICE BULLETIN WHICH INCLUDE REMOVING THE ENGINE FROM THE PYLON BEFORE REMOVING THE PYLON FROM THE WING. (URGENT)
In plain language (FlightFinder summary)
The FAA must issue a maintenance alert bulletin directing its inspectors to contact airlines and tell them to stop the practice of lowering or raising the pylon while the engine is still attached. Airlines should instead follow the Douglas Aircraft Company service bulletin procedure that requires removing the engine from the pylon before removing the pylon from the wing.
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.
