Airworthiness Directives; Boeing Model 727 Series Airplanes

This document corrects information in an existing airworthiness directive (AD) that applies to certain Boeing Model 727 series airplanes. That AD supersedes an earlier airworthiness directive to require repetitive inspections to detect cracking of the rear spar web or fuel leakage of the wing center section; repair, if necessary; and modification of the rear spar web. This document corrects the effective date of the earlier, superseded AD, which was stated incorrectly in the existing AD. This correction is necessary to ensure that operators are advised of the correct effective date of the original AD, specifically as it affects the compliance time for a certain paragraph of this AD.
