Boeing 787: FAA bans dispatch under specific engine MEL relief
An airworthiness directive from the FAA prevents dispatching select Boeing 787-8 and 787-9 jets due to unverified engine operability data under MEL relief.
The FAA has adopted a new airworthiness directive addressing certain airplanes manufactured by The Boeing Company, specifically covering Model 787-8 and Model 787-9 aircraft.
The regulatory decision originates from a report indicating a lack of substantiating data regarding engine operability whenever an airplane is dispatched under a certain item from the master minimum equipment list. Without these required supporting elements, the actual operating capability of the engines cannot be properly confirmed for departure.
Consequently, this directive legally prohibits dispatching an affected airplane under the operational procedures associated with an operator's minimum equipment list item that corresponds to the referenced MMEL provision.
Through the issuance of this mandatory airworthiness directive, the agency is actively acting to address and resolve this identified unsafe condition on the concerned airplanes to maintain operational safety.
Why it matters for your training
Pilots must closely crosscheck MEL relief procedures before departure to ensure that aircraft dispatch complies with approved engine operability data.
