04-8296. Airworthiness Directives; Boeing Model 737-300, -400, and -500 Series Airplanes

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule; correction.

SUMMARY:

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.

DATES:

Effective March 24, 2004.

SUPPLEMENTARY INFORMATION:

Airworthiness Directive (AD) 2004-04-03, amendment 39-13483, applicable to certain Boeing Model 737 series airplanes, was published in the Federal Register on February 18, 2004 (69 FR 7565). That 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.

As published, that final rule incorrectly specifies “September 26, 2001” as the effective date for AD 2000-10-21 in the compliance time specified for Group 1 airplanes in Table 1 of that final rule. The correct effective date of AD 2000-10-21 is “June 12, 2000.” It was the FAA's intent that operators use June 12, 2000, to determine the compliance time for Group 1 airplanes as specified in Table 1 of that final rule, as evidenced by the explanatory parenthetical reference “(the effective date of AD 2000-10-21, amendment 39-11745).”

Since no other part of the regulatory information has been changed, the final rule is not being republished in the Federal Register.

The effective date of this AD remains March 24, 2004.

§ 39.13

[Corrected]

On page 7566, the second column of Table 1 of AD 2004-04-03 is corrected to read as follows:
