What was found
UPON LANDING THE AIRCRAFT, THE LANDING GEAR FAILED TO EXTEND DUE TO A MALFUNCTION OF THE LANDING GEAR MOTOR CONTRACTOR. PROBLEM WAS DUPLICATED WITH THE AIRCRAFT ON JACKS. TAPPING THE CONTACTOR WITH THE LANDING GEAR SELECTOR IN THE DOWN POSITION WOULD OPERATE THE LANDING GEAR. REPLACEMENT OF THE CONTACTOR CORRECTED THE GEAR MALFUNCTION.
