AD FAA-2012-0105

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD was prompted by reports of fractured and missing latch pin retention bolts that secure the latch pins on the forward cargo door. This AD requires repetitive detailed inspections for fractured or missing latch pin retention bolts, replacement of existing titanium bolts with new Inconel bolts, and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct fractured and missing latch pin retention bolts, which could result in potential separation of the cargo door from the airplane and catastrophic decompression of the airplane.
