Airworthiness Directive · Amendment 39-13137 · Boeing Model 767-200, -300, and -300F Series Airplanes
Boeing Model 767-200, -300, and -300F Series Airplanes
Model 767-200, -300, and -300F series airplanes; line numbers 1 through 710 inclusive; certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to all Boeing Model 767 series airplanes, that currently requires an inspection to ensure that all bolts of the support beam of the hinge fitting assembly on both the left- and right- hand outboard trailing edge flaps are the correct length and type, and correction of any discrepancy found. This amendment reduces the applicability of the existing AD, adds inspections, and mandates terminating action. The actions specified by this AD are intended to prevent failure of the bolts that attach the outboard trailing edge flap to the support beam, which could result in loss of the flap and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
