Plain English Summary

4/10 complexity

This AD requires Australian-registered aircraft with GE CF6-80A or CF6-80C2 engines to comply with FAA AD 91-11-05 and the cited GE service bulletins (effective 5 Sep 1991). It mandates inspections/repairs to address inertia-weld failures on the high-pressure compressor rotor; operators must perform and pay for the work to mitigate risk of major power loss or ejected parts.
