Airworthiness Directive · Amendment 39-10859 · Boeing Model 767 Series Airplanes
Boeing Model 767 Series Airplanes
Superseded. A later AD replaced this one: AD 2003-14-09. Comply with the one in force.
Model 767 series airplanes, line numbers 1 through 721 inclusive, certificated in any category.
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.
