NTSB Urges FAA Airworthiness Directive for GEnx Engine Fan Shafts

The National Transportation Safety Board (NTSB) has released Recommendation A-12-052, identified by NTSB number DCA12IA114. This urgent directive is addressed to the Federal Aviation Administration. The board is calling for the issuance of an airworthiness directive that would require ultrasonic inspection of the fan midshaft in all General Electric GEnx-1B and -2B engines. This requirement applies to any engine that has not yet undergone such inspection before further flight. The NSB emphasizes the urgent nature of this safety concern for these specific engine models.
