FAA issues emergency AD for GP7200 engine fan hub inspections after Air France accident
13 October 2017

The FAA issued an emergency airworthiness directive (AD) prompted by the recent an uncontained engine failure that occurred on Air France Airbus A380 powered by 
Engine Alliance (EA) GP7270 turbofan engines. 

On September 30, Air France flight 66 suffered an uncontained failure of the no.4 engine while en route over Greenland. The entire fan and engine air inlet cowling broke away. This prompted the crew to divert to Goose Bay, Canada.

The FAA reported in their AD that the failure occurred on an Engine Alliance GP7270 turbofan engine that had 3,527 cycles since new, which
is a relatively high cycle engine.

The AD requires a one-time visual inspection of the GP7200 series engine fan hub, with the compliance time based on the number of accumulated flight cycles, and removal of the fan hub if
damage or defects are found that are outside of serviceable limits. These interim actions are intended to prevent failure of the fan hub, which could lead to an uncontained release of the fan hub, damage to the engine, and damage to the airplane.

The GP7200 series engine is in use by A380-861 aircraft of Air France, Etihad Airways, Korean Air, and Qatar Airways, as well as 90 of the 142 A380s ordered by Emirates.
