Applicability*9

This AD applies to all The Boeing Company Model 787-8 airplanes, certificated in any category.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

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.

Unsafe condition

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. We are issuing this AD to address potential failure of the restraint system of the attendant seat during turbulence or a high-G load event, which could result in serious injury.

Affected ADs

None.
