Airworthiness Directives; The Boeing Company Model 767-200, -300, and -300F Series Airplanes

摘要

The FAA is superseding an existing airworthiness directive (AD) that applies to certain Model 767-200, -300, and -300F series airplanes. The existing AD currently requires repetitive detailed and eddy current inspections to detect cracks or corrosion of certain midspar fuse pins, and corrective actions if necessary. That AD also provides optional terminating action, which ends the repetitive inspections. This new AD requires reduced intervals for certain repetitive inspections. This AD results from a report of a fractured midspar fuse pin. We are issuing this AD to prevent loss of the strut and engine due to corrosion damage and cracking of both fuse pins on the same strut.
