Airworthiness Directive · Amendment 39-19277 · Equipment/furnishings
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 787-8 airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8 airplanes. This AD requires inspecting the part number of the occupant restraint system on the standard attendant seats, and doing additional inspections and corrective actions if necessary. This AD was prompted by a report of loose attachment bolts on the occupant restraint system on a standard attendant seat due to the bolts being over-torqued during production. We are issuing this AD to address the unsafe condition on these products.
Within 5 years after the effective date of this AD: Inspect the occupant restraint system on the standard attendant seats for any restraint system having a part number identified in the Accomplishment Instructions of Boeing Service Bulletin B787-81205-SB250052-00, Issue 001, dated January 27, 2014.
(1) For any affected occupant restraint system: Within 5 years after the effective date of this AD, inspect the affected attendant seat for discrepancies, including a general visual inspection for any gap of the interface of the lever and spacer, a general visual inspection for any flattened or stripped threads, verification that the lap belt bolt helicoil in the lever does not protrude beyond the bottom surface of the counterbore, and a general visual inspection for visible metal shavings or fragments of the lap belt bolt and lever helicoil; and do all applicable torqueing of the lap belt bolt, in accordance with the Accomplishment Instructions of Boeing Service Bulletin B787-81205-SB250052-00, Issue 001, dated January 27, 2014.
(2) For any discrepant attendant seat, before further flight rework the attachment bolt, the seat pan lever and bolts, and the dampener bolt, in accordance with the Accomplishment Instructions of Boeing Service Bulletin B787-81205-SB250052-00, Issue 001, dated January 27, 2014.
Note 1 to paragraph (g) of this AD: Guidance on the inspections and rework can be found in Goodrich Service Bulletin 2787-25-009, dated June 28, 2013.
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.”
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
