Boeing Model 767-200 and 767-300 Series Airplanes
This AD applies to Boeing Model 767-200 and 767-300 series airplanes equipped with center overhead stowage bin modules, certificated in any category; as identified in Boeing Special Attention Service Bulletin 767-25-0320, dated April 11, 2002.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-200 and 767-300 series airplanes. This AD requires performing a general visual inspection to determine the part number of the I-beams of the center overhead stowage bin modules to identify I-beams having 9.0g (gravitational acceleration) tie rods attached and to determine the configuration of the center overhead stowage bin modules. For certain center overhead stowage bin modules, this AD requires installing support straps. This AD results from tests conducted by the airplane manufacturer. We are issuing this AD to prevent failure of the attachment of the 9.0g tie rods to the center overhead stowage bin modules. This failure could result in collapse of those stowage bin modules, and consequent injury to passengers and crew and interference with their ability to evacuate the airplane in an emergency.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 36 months after the effective date of this AD: Perform a general visual inspection of the center overhead stowage bin modules to determine the P/N of each I-beam and to determine the configuration of each center overhead stowage bin module. Do the inspection in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-25-0320, dated April 11, 2002.
Note 1: For the purposes of this AD, a general visual inspection is: “A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to ensure visual access to all surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.”
(g) For any I-beam found having P/N 412T2040-29 during the inspection required by paragraph (f) of this AD: No further action is required by this AD for that I-beam only.
For any I-beam found having a P/N other than P/N 412T2040-29 during the inspection required by paragraph (f) of this AD: Before further flight, do the actions in paragraph (h)(1) or (h)(2) of this AD, as applicable, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-25-0320, dated April 11, 2002.
(1) If the forward-most stowage bin module was inspected: Before further flight, install support straps having P/N 412T2043-101 and 412T2043-102 on the center overhead stowage bin module, in accordance with Figures 3, 4, and 5 of the Accomplishment Instructions of the service bulletin.
(2) If the stowage bin module inspected was other than the forward-most stowage bin module: Before further flight, do the actions specified in paragraph (h)(2)(i) or (h)(2)(ii) of this AD, as applicable.
(i) For center overhead stowage bin modules having “Configuration A,” as specified in the service bulletin: Before further flight, do the actions specified in paragraph (h)(1) of this AD.
(ii) For center overhead stowage bin modules having a configuration other than “Configuration A,” as specified in the service bulletin: Before further flight, install two support straps having P/N 412T2043-119 on the center overhead stowage bin module, in accordance with Figures 3, 4, and 6 of the Accomplishment Instructions of the service bulletin.
