Airworthiness Directives; Boeing Model 737-300, -400, and -500 Series Airplanes

This document corrects a typographical error that appeared in airworthiness directive (AD) 2004-04-03 that was published in the Federal Register on February 18, 2004 (69 FR 7565). The typographical error resulted in a reference to an incorrect effective date in the compliance time specified in Table 1 of the AD for Group 1 airplanes. This AD is applicable to certain Boeing Model 737 series airplanes. This AD requires a one-time general visual inspection of the seat locks and seat tracks of the flightcrew seats to ensure that the seats lock in position and to verify that lock nuts and bolts of adequate length are installed on the rear track lock bracket, and corrective action, if necessary.
