Airworthiness Directive · Amendment 39-11044 · Boeing Model 777 Series Airplanes
Boeing Model 777 Series Airplanes
Superseded. A later AD replaced this one: AD 2000-19-08. Comply with the one in force.
All Model 777 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 777 series airplanes. This action requires repetitive detailed visual inspections to detect cracking of the cove skin on the outboard leading edge slats; a slat adjustment check; and corrective actions, if necessary. This amendment is prompted by reports of fatigue cracking and/or missing pieces of the cove skin on the outboard leading edge slats. The actions specified in this AD are intended to detect and correct such discrepancies, which could result in skin separation or structural damage to the leading edge slats, and consequent reduced controllability of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
