Probable cause & findings

THE LANDING GEAR WAS EITHER NOT FULLY EXTENDED DURING THE LANDING OR IT RETRACTED DURING THE LANDING ROLL FOR AN UNDETERMINED REASON.

Factual narrative

THE INSTRUCTOR PILOT AND THE DUAL STUDENT STATED THAT THE NOSE GEAR AND THEN THE MAIN GEAR COLLAPSED AFTER THE AIRPLANE TOUCHED DOWN ON ITS GEAR, WITH THE GREEN (GEAR DOWN AND LOCKED) LIGHT ON. THERE WAS EVIDENCE THAT THE GEAR WAS UP AND LOCKED WHEN THE AIRPLANE TOUCHED DOWN ON THE RUNWAY. WHEN CHECKED, ONE OF THE LNDG GEAR CIRCUIT BREAKERS (FOR THE DYNAMIC BRAKE RELAY) WOULD 'POP.' THE PURPOSE OF THE DYNAMIC BRAKE RELAY WAS TO KEEP THE LANDING GEAR MOTOR FROM OVERRUNNING & JAMMING IN THE UP OR DOWN POSITION. THE GEAR EXTENSION/RETRACTION SYSTEM (INCLUDING THE INDICATOR LIGHTS & WARNING HORN) OPERATED NORMALLY. ALSO, THE UP/DOWN LOCK POSIITON APPEARED TO BE CORRECT, NO PART FAILURE OR MALFUNCTION WAS FOUND THAT WOULD HAVE RESULTED IN THE ACDNT.
