Docket No. 97-NM-334-AD
Abstract
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 737, 747, 757, and 767 series airplanes, that currently requires 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. This amendment revises the applicability of the existing AD. The actions specified in this AD are intended to prevent uncommanded movement of the pilots' seats during acceleration and take-off of the airplane, and consequent reduced controllability of the airplane.
