Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Boeing Model 767 series airplanes. This proposal would require inspections of the components of the leading edge outboard slat; replacement of the control rod end, if necessary; and various follow-on actions. This proposal is prompted by reports of skewed panels of the outboard leading edge slat due to either corrosion of the rotary actuator, cracking of the control rod, or incorrect clearance of the overtravel stop of the outboard leading edge slat. The actions specified by the proposed AD are intended to prevent such conditions, which could result in reduced controllability of the airplane and damage to or cracking of the leading edge slats or the fixed leading edge of the wing.
