## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 777-200, -200LR, -300, and -300ER series airplanes. This proposed AD would require doing initial and repetitive inspections for cracking of the elevator actuator fittings, and replacing any cracked fitting with a new fitting. This proposed AD results from a report that a cracked left elevator actuator fitting was found on a Model 777 airplane. We are proposing this AD to detect and correct a cracked actuator fitting, which could detach from the elevator and lead to an unrestrained elevator and an unacceptable flutter condition, which could result in loss of airplane control.
