FAA mandates A380 engine seal replacements after aborted takeoff (simpleflying.com)

The Federal Aviation Administration has ordered urgent replacement of 15 high-pressure turbine interstage seals on Engine Alliance GP7200-series engines after an uncontained failure forced an Airbus A380 to abort takeoff. The directive, effective October 23, requires the most urgent replacements within 50 flight cycles or 30 days, with costs estimated at $528,150 per affected engine. The FAA adopted the rule without public consultation due to safety risks, and further rulemaking may follow pending the root-cause investigation.
