Airworthiness Directive · Amendment 39-10239 · Boeing Model 727 Series Airplanes
Boeing Model 727 Series Airplanes
Superseded. A later AD replaced this one: AD 2000-14-07. Comply with the one in force.
Model 727 series airplanes having line numbers 858 through 864 inclusive, 867 through 869 inclusive, 872 through 883 inclusive, and 885 through 1832 inclusive; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 727 series airplanes. This action requires repetitive inspections to detect cracking of the rear spar web or fuel leakage of the wing center section, and repair, if necessary. This amendment also provides for an optional modification of the rear spar web that constitutes terminating action for the repetitive inspections. This amendment is prompted by several reports of fuel leakage due to cracking of the rear spar web of the wing center section. The actions specified in this AD are intended to detect and correct such cracking of the rear spar web, which could permit fuel leakage into the airflow multiplier, and could result in an electrical short that could cause a fire.
