Action

Notice of proposed rulemaking (NPRM).

Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2012-07-06, which applies to certain The Boeing Company Model 777 airplanes. AD 2012-07-06 requires revising the maintenance program to update inspection requirements to detect fatigue cracking of principal structural elements. Since the FAA issued AD 2012-07-06, the FAA has determined that new and more restrictive airworthiness limitations are necessary. This proposed AD would retain the requirements of AD 2012- 07-06 until the new or more restrictive airworthiness limitations are incorporated. The FAA is proposing this AD to address the unsafe condition on these products.
