## Summary

The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain Boeing Model 767-300 and -300F series airplanes. The proposed AD would have required a one-time operational test of the pilots' seat locks and the seat tracks to ensure that the seats lock in position and the seat tracks are aligned correctly; and re-alignment of the seat tracks, if necessary. Since the proposed AD was issued, we have received new data that the affected airplanes are included in the applicability of an existing AD that addresses the unsafe condition. Accordingly, the proposed AD is withdrawn.
