Boeing Model 767-200 and -300 Series Airplanes Equipped With Off-Wing Escape Slides
Model 767-200 and -300 series airplanes equipped with off-wing escape slides; certificated in any category.
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.
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, accomplish the following:
(a) Within two years after the effective date of this AD, do 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, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-25-0299, dated January 18, 2001.
(b) If any actuator cartridge having serial numbers 5481 through 5741 inclusive is found during the inspection required by paragraph (a) of this AD: Before further flight, perform the actions specified in paragraphs (b)(1) through (b)(3) of this AD in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-25-0299, dated January 18, 2001.
(1) Remove the door-opening actuator for the off-wing slide compartment.
(2) Perform an inspection of the actuator cartridge for the presence of a clearance hole and corrective actions, if necessary (includes replacing the actuator cartridge with a new actuator cartridge or a serviceable actuator cartridge from a recharge kit).
(3) Install the door-opening actuator for the off-wing slide compartment.
Note 1: Boeing Special Attention Service Bulletin 767-25-0299, dated January 18, 2001, references OEA Aerospace, Inc. Service Bulletin 5262 (02) SB (NC), dated October 2, 2000, as an additional detailed source of service information for performing the inspection of the actuator cartridge and corrective actions.
(c) As of the effective date of this AD, no person shall install, on any airplane, an actuator for the off-wing escape slide having OEA part number 5262200 cartridge assembly, with actuator cartridge serial numbers 5481 through 5741 inclusive, that does not have a clearance hole between the two firing pins.
(d) In accordance with 14 CFR 39.19, the Manager, Seattle Aircraft Certification Office, FAA, is authorized to approve alternative methods of compliance for this AD.
