Airworthiness Directive · Amendment 39-12128 · Boeing Model 767 Series Airplanes
Boeing Model 767 Series Airplanes
Superseded. A later AD replaced this one: AD 2013-25-03. Comply with the one in force.
All Model 767 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 767 series airplanes. This action requires repetitive testing of the elevator control system to determine if an elevator power control actuator (PCA) is rigged incorrectly due to yielded or failed shear rivets in a bellcrank assembly for the elevator PCA, and follow-on actions, if necessary. This action is necessary to prevent continued operation with yielded or failed shear rivets in a bellcrank assembly for the elevator PCA, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
