Airworthiness Directives; General Electric Company (GE) GE90 Series Turbofan Engines

The FAA is adopting a new airworthiness directive (AD) for GE GE90-110B1, -113B, and -115B series turbofan engines with certain Turbine Center Frames (TCFs) installed. This AD requires removing certain TCFs, listed by part number (P/N) in this AD, from service before exceeding 14,300 flight cycles. This AD results from a report that GE inadvertently omitted some TCF P/Ns from the Airworthiness Limitations Section (ALS) of the engine manual. We are issuing this AD to prevent structural failure of the TCF with uncontained failure of low pressure turbine (LPT) rotating parts. Uncontained failure of the LPT rotating parts could result in damage to the airplane and possible loss of control of the airplane.
