Airworthiness Directive · Amendment 39-12723 · Boeing Model 767 Series Airplanes
Boeing Model 767 Series Airplanes
Model 767 series airplanes, line numbers 160 through 541 inclusive, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that requires an inspection of the tripod strut assembly of the inboard support of the leading edge slat of the wing for a preload condition, and follow- on actions. For certain airplanes, this AD also requires inspection and replacement of the existing tripod struts with new, adjustable struts, if necessary. This action is necessary to prevent damage to the tripod strut assembly due to a preload condition, which could result in loss of control of the inboard leading edge slat or separation of the slat from the airplane, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
