(2) Inspection of the wiring to the fuel pumps, fuel level switches, the refuel shutoff valves, and optical sensors/mechanical switches, and if any damage is found, contact Saab for repair instructions and repair before further flight. (3) Twisting of the fuel pump wiring, fuel level switches wiring, refuel shutoff valves wiring, and optical sensors/mechanical switches wiring. (4) Installation of a shrinkable tube to the fuel pumps wiring, fuel level switches wiring, refuel shutoff valves wiring and optical sensors/mechanical switches wiring. (5) Installation of fuel pumps, the fuel level switches, the refuel shutoff valves, and the optical sensors/mechanical switches. (6) Operational and functional test of the fuel measuring/indicating system. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: (1) The MCAI does not specify corrective action for the inspection specified in paragraph (f)(2) of this AD. This AD requires contacting Saab for repair instructions and repairing before further flight. (2) The MCAI does not include actions for optical sensors/mechanical switches 13QA and 14QA; however, paragraph (f) of this AD includes modification of those optical sensors/mechanical switches.
