What was found
FOUND S32020 NLG DOOR CLOSE SWITCH WOULD CLOSE NOSE DOORS WITHOUT S32018 NLG ARM SWITCH BEING ACTIVATED TO ARM. UPON INSPECTION OF SWITCH S32020 AND S32018 WE FOUND THAT THE WIRE 1007-18 AND 1006-18 ARE IN THE WRONG POSITION REF WDM 32-35-12-1. WIRE 1007-18 WAS FOUND AT THE #3 ON S32020 CAUSING THE NOSE LANDING GEAR DOOR UNSAFE LIGHT TO REMAIN ILLUMINATED WITH THE SWITCH IN THE OFF POSITION FOUND WIRE 1006-18 IN THE #1 POSITION ON S32020. BECAUSE THIS WIRE WAS IN THE WRONG LOCATION, THIS ALLOWED POWER TO FLOW IN REVERSE CLOSING THE MAIN LANDING GEAR DOOR WHEN S32020 IS MOVED TO THE CLOSED POSITION. WIRES HAVE BEEN RE-ROUTED TO CORRECT POSITIONS REF WDM 32-35-12-1. OPS CHECK NEEDED REVIEW LP UPDATES. ESSENTIALLY, SWITCHES WERE WIRED INCORRECTLY CAUSING THE WRONG LANDING GEAR DOORS TO RETRACT UNCONTROLLABLY. THIS COULD HAVE CAUSED SERIOUS INJURY TO PERSONNEL AND DAMAGE TO EQUIPMENT AND AIRCRAFT. OPS CHECKED GOOD.
