## Abstract

We are adopting a new airworthiness directive (AD) for all General Electric Company (GE) CF34-8E model turbofan engines. This AD was prompted by a report that using a certain repair procedure for the fan outlet guide vane (OGV) frame could alter the strength capability of the fan OGV frame. This AD requires replacement of all fan OGV frames repaired using this procedure. We are issuing this AD to address the unsafe condition on these products.
