This AD was prompted by a report of an in-flight increase ofN2 intermediate pressure 

rotor vibrations resulting in an engine surge and pilot shut down of the engine. We are 

issuing this AD to prevent rotor bearing oil starvation, uncontained engine failure, and 

damage to the airplane.

FEDERAL REGISTER]. 

We must receive comments on this AD by [INSERT DATE 45 DAYS AFTER
