AD NUMBER: 2010-26-08

MANUFACTURER: The Boeing Company Model 767 Airplanes
SUBJECT: Airworthiness Directive 2010-26-08

SUMMARY:We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires a detailed inspection of the entryway door movable ceiling panel for pin migration at either end of the hinge assembly and damage to the pin; a detailed inspection for correct crimp at both ends and damage to hinge stock; a detailed inspection of the ceiling area for any visible cosmetic and/or tie-rod chafing that could be caused by a migrated hinge pin; a detailed inspection for wire damage and/or breakage; and other specified and corrective actions if necessary. This AD results from reports of fault messages caused by improperly crimped hinge pins coming into contact with wires and causing damage. We are issuing this AD to detect and correct improperly crimped hinge pins, which could damage tie rods and
wire bundles, causing shorts in many systems, including the spar fuel shut-off valve, oxygen mask deployment, and burned wires, which could be an ignition source in a hidden area of the airplane.

DATES: This AD is effective February 1, 2011.
