Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all General Electric Company (GE) CF6-80C2A1, CF6-80C2A2, CF6- 80C2A3, CF6-80C2A5, CF6-80C2A5F, and CF6-80C2A8 model turbofan engines with an installed left-hand rear mount link assembly, part number (P/N) 1846M23G01. This proposed AD was prompted by the manufacturer reducing the life limit for the affected left-hand rear mount link assembly. This proposed AD would require revising the Airworthiness Limitations section (ALS) of the GE CF6-80C2 Engine Manual, GEK92451, and the operator's existing approved continuous airworthiness maintenance program (CAMP). The FAA is proposing this AD to address the unsafe condition on these products.
