Airworthiness Directives; Boeing Model 767-200 and -300 Series Airplanes Equipped With Off-Wing Escape Slides

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767-200 and -300 series airplanes equipped with off-wing escape slides, that requires an inspection of the door-opening actuators for the off-wing slide compartment on the right and left sides of the airplane to determine the actuator cartridge serial number, and corrective actions, if necessary. This action is necessary to prevent the door-opening actuators for the off- wing slide compartment from not firing, which could cause the door to open improperly and prevent the deployment of the off-wing escape slide, leading to the loss of an evacuation route. This action is intended to address the identified unsafe condition.
