            Note 1: For the purposes of this Directive, a detailed inspection is defined as: "An intensive visual examination of a specific structural area, system, installation, or assembly to detect damage, failure, or irregularity.

 AD/HS 125/173 (continued)

            Background: This Directive requires a one-time inspection of certain wire bundles for discrepancies and related corrective action. This action is necessary to find and fix chafing and damage to the wire bundles, which if left could result in electrical arcing and heat damage in a potential fuel zone together with possible fire or explosion in the fuel tank.
