A proposal is not in force. If adopted, it becomes an AD, usually with changes. Only the Federal Register edition is official.

Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports of damage to the thrust reverser (TR) translating sleeve secondary sliders due to contact between the slider and the slider track liner. This damage was only found on TR sleeves installed on certain engines. This proposed AD would require determining the serial number of the TR and performing applicable on-condition actions; or replacing the TR with a serviceable TR. The FAA is proposing this AD to address the unsafe condition on these products.

The resulting AD
