As a result of the uncontained engine fan failure on AF66 on Sept 30th 2017;

Operators of Airbus A380s with Engine Alliance GP7200 powerplants are being ordered to conduct an urgent inspection of the engines' fan hubs for damage.

The US FAA's emergency directive follows the uncontained failure of a GP7200 which, it says, had accumulated 3,527 cycles since new.

It describes the powerplant as a "relatively high cycle engine". The directive requires removal of the fan if damage or defects are found during the one-time visual inspection.

Investigators have been probing the uncontained GP7200 fan failure on an Air France A380 over Greenland on 30 September. The aircraft, bound for Los Angeles, diverted to Goose Bay in Canada.

The directive is intended to prevent failure of the fan hub, damage to the engine, and potential damage to the airframe.
