FAA Issues AD for GEnx-1B and 2B Engines
October 04, 2012
As expected, the FAA issued an airworthiness directive (AD) on Sept. 21 for certain General Electric next generation (GEnx) engines. The AD requires ultrasonic inspections of the fan midshaft described in GE Service Bulletin (SB) No GEnx-2B S/B 72-0091, Revision 1 or No.GEnx-1B S/B 72-107, Revision 2, dated September 14, 2012, as applicable, before further flight.
The agency’s action follows a National Transportation Safety Board letter urging the issuance of the AD.
