As has widely been reported, operators of the Boeing 787 Dreamliner are required to comply with an Air Worthiness Directive issued by the Federal Aviation Administration in the United States.
The FAA Directive
The FAA Directive applies to operators of the Boeing 787 Dreamliner with certain engine models manufactured by Rolls Royce.
It limits the scope of the ETOPS (“Extended-range Twin-engine Operational Performance Standard”). ETOPS allows twin-engined aircraft like the Boeing 787 to operate between 60 and 330 minutes’ away from the nearest airport that can handle a diversion of the aircraft. This Directive may be modified subject to remedial action by Rolls Royce.
The requirement for additional maintenance to Rolls Royce engines has been going on for some time and has impacted a number of airlines, notably Air New Zealand, Norwegian and Virgin Atlantic. All have leased in aircraft to cover some flights. BA has also cancelled its flight to Doha for an extended period of time to release aircraft for other routes.
BA has made no official statement on the impact of this directive on the airline. As such, it is not known how many of its aircraft are affected. However, as BA currently operates the Boeing 787 Dreamliner on a number of long-range routes to Asia and Latin America, it will inevitably have an impact on the airline’s operations.
BA may choose to substitute aircraft at short notice, or cancel flights as aircraft undergo maintenance.
