Group 1-10:
1. CONCURRENT REQUIREMENTS
Refer to data module Data Module SB B787-A-25-00-0052-00A-932A-D, Paragraph 2., Concurrent Require-
ments.
2. BACKGROUND
This service bulletin provides instructions to inspect attendant seats and replace the lap belt attachment
bolt and seat pan lever if required. Attachment bolts were found loose by an operator and subsequent
analysis by the supplier determined that the losseness was caused by the bolt being over-torqued. If this
bulletin is not incorporated, an attendant seat with a loose attendant bolt may not restrain the seat occupant
properly and lead to serious injury during a turbulence or a high G event.
An operator reported that a seat belt lower mount helicoil was detached from the seat pan lever while the
attachment bolt was still threaded into the helicoil. The supplier investigated and found that the attachment
bolt was most likely over-torqued during production. Over-torquing the attachment bolt may damage the
bolt or the helicoil installation and reduce the strength of the restraint system.
Boeing Service Related Problem (SRP) 787 25-0329 is related to this service bulletin.
This table is provided to operators for planning purposes only. Refer to the applicable sections for more in-
