Boeing Model 767-300 and -400ER Series Airplanes
Model 767-300 series airplanes, as listed in Boeing Alert Service Bulletin 767-38A0062, dated August 15, 2002; and Model 767-400ER series airplanes, as listed in Boeing Alert Service Bulletin 767-38A0063, dated August 15, 2002; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767-300 and -400ER series airplanes, that requires replacing the tie rods for the waste tank cradle, related investigative actions, corrective actions, and special retrofit action if necessary. This action is necessary to prevent possible failure of the main deck floor stanchions and consequent collapse of the main floor during an emergency landing, which could result in passenger injury and impede passenger evacuation from the airplane. This action is intended to address the identified unsafe condition.
To prevent failure of the main deck floor stanchions and consequent collapse of the main floor during an emergency landing, which could result in passenger injury and impede passenger evacuation from the airplane, accomplish the following:
(a) Within 18 months after the effective date of this AD: Replace the four tie rods for the waste tank cradle with new tie rods and do all applicable related investigative actions, corrective actions, and special retrofit actions by accomplishing all the actions in the Accomplishment Instructions of Boeing Alert Service Bulletins 767-38A0062 (for Model 767-300 series airplanes) and 767-38A0063 (for Model 767-400ER series airplanes), both dated August 15, 2002; as applicable. Do the actions in accordance with the applicable service bulletin except as provided by paragraph (b) of this AD. Accomplish any related investigative, corrective, or special retrofit action before further flight.
(b) If any deformation, crack, or other damage is found during any related investigative action required by paragraph (a) of this AD, and the bulletin specifies contacting Boeing for appropriate action: Before further flight, perform the special retrofit action per a method approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA. For a retrofit method to be approved by the Manager, Seattle ACO, as required by this paragraph, the Manager's approval letter must specifically refer to this AD.
(c) As of the effective date of this AD, no person may install any tie rod for the waste tank cradle having part number 251T0100-1401, 251T0100-1402, 251T0100-1403, or 251T0100-1404, on any airplane to which this AD applies.
(d) In accordance with 14 CFR 39.19, the Manager, Seattle ACO, FAA, is authorized to approve alternative methods of compliance (AMOCs) for this AD.
(e) Unless otherwise specified in this AD, the actions shall be done in accordance with Boeing Alert Service Bulletin 767-38A0062, dated August 15, 2002; and Boeing Alert Service Bulletin 767-38A0063, dated August 15, 2002; as applicable.
