## Summary

We propose to adopt a new airworthiness directive (AD) for certain serial number GE Aviation Czech s.r.o. M601E-11, M601E-11A, and M601F turboprop engines with certain part number (P/N) gas generator turbine (GGT) blades, installed. This proposed AD was prompted by the determination that certain GGT blades are susceptible to blade failure. This proposed AD would require removing from service any affected engine with certain GGT blades installed. We are proposing this AD to prevent GGT blade failure, which could lead to engine failure and loss of the airplane.
