## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing airplanes. The existing AD currently requires inspection of the attachment of the shoulder restraint harness to the mounting bracket on certain observer and attendant seats to determine if a C-clip is used in the attachment, and corrective action, if necessary. This proposed AD would remove certain airplanes from the applicability and add others. This proposed AD results from the determination that some airplanes had been inadvertently included in or excluded from the applicability of the existing AD and that certain additional new airplanes are now subject to the identified unsafe condition. We are proposing this AD to prevent detachment of the shoulder restraint harness of the attendant or observer seat from its mounting bracket during service, which could result in injury to the occupant of the seat.
