## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GE90-115B model turbofan engines. Emergency AD 2019-21-51 was sent previously to all known operators of the GE GE90-115B model turbofan engines with certain engine serial numbers. This AD requires the removal from service of the Interstage Seal, part number 2505M72P01, from the affected engines. This AD was prompted by a recent event involving an uncontained high-pressure turbine (HPT) failure, resulting in an aborted takeoff and debris penetrating the airplane's fuselage and the other engine. The FAA is issuing this AD to address the unsafe condition on these products.
