## Summary

We propose to adopt a new airworthiness directive (AD) for all General Electric Company (GE) CF34-8E model turbofan engines. This proposed 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 proposed AD would require replacement of all fan OGV frames repaired using this procedure. We are proposing this AD to correct the unsafe condition on these products.
