This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to ensure visual access to all surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.” Further Corrective Actions (g) If any broken, frayed, cracked, or damaged wire, or a damaged harness, is found: Before further flight, repair the damaged wire or harness in accordance with a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA.

This AD results from a report that the fuel quantity indication system (FQIS) wire harness may not be properly attached at its attachment points or properly separated from the direct current (DC) fuel pump wire harness. We are issuing this AD to prevent chafing between those harnesses or chafing of the harnesses against adjacent airplane structure or components, which could present a potential ignition source that could result in a fire or explosion.
