            Background: This Directive requires repetitive inspections for damage or arcing of the IDG power feeder cables and conduit in the forward section of all four struts together with any necessary repairs. The Directive also requires repetitive inspections for chafing damage or arcing of the adjacent hydraulic lines in the aft section of the outboard struts. Additionally, the Directive introduces eventual terminating actions for the repetitive inspections.

            These action are necessary to prevent damage and arcing to the conduit and power feeder cables of the IDG, which could result in a fire in the engine strut; and to prevent damage to the adjacent hydraulic lines in the aft section of the outboard struts, which could result in reduced controllability of the aeroplane.
