Airworthiness Directives; Boeing Model 767 Series Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 767 series airplanes. This action requires repetitive detailed visual inspections to detect cracked, corroded, or stained collar fittings on both inboard trailing edge flaps; and follow-on corrective actions, if necessary. This amendment is prompted by a report indicating that a collar fitting suffered a complete fracture as a result of stress corrosion cracking. The actions specified in this AD are intended to prevent separation of the inboard trailing edge flap from the airplane due to fractured collar fittings.
