What was found
AFTER THE ABOVE AIRCRAFT WAS FERRIED DUE TO A GEAR INDICATION PROBLEM, THE LANDING GEAR SELECTOR VALVE WAS FOUND AT FAULT. UPON REPLACING THE INITIAL SELECTOR VALVE (P/N 7SC0143) WITH THE ABOVE (S/N 433) AND GEAR SWINGS WERE CARRIED OUT IT WAS DISCOVERED THAT WHEN THE GEAR WAS SELECTED UP THE GEAR WOULD GO DOWN AND WHEN THE GEAR WAS SELECTED DOWN THE GEAR WOULD GO UP. A SECOND LANDING GEAR SELECTOR VALVE WAS INSTALLED GEAR SWINGS CARRIED OUT AND THE AIRCRAFT WAS RETURNED TO SERVICE.
