FAA mandates replacement of specific A380 engine seals after uncontrolled failure

The FAA issued a flightworthiness directive on 8 October 2026 requiring the replacement of high‑pressure turbine intermediate stage seals on GP7270, GP7272 and GP7277 engines, with the directive taking effect on 23 October 2026 and applying only to parts that meet defined technical criteria. The action follows an uncontrolled engine failure that forced an Airbus A380 to cancel takeoff after a GP7270 seal failed, though the airline and aircraft registration were not disclosed. The FAA advises removing and replacing the 15 seals that have accumulated 50 to 150 cycles or 30 to 90 days of service, whichever occurs first, and notes that no U.S.-registered aircraft are affected.

Engine Alliance issued a service bulletin on 4 September 2026 detailing the required replacement parts, and the FAA estimated the cost of the replacement at $528,150 per affected engine, of which $527,300 is for the parts.
