Narrative:

In preparing for landing at onp, the right main gear light did not light. Several weeks ago, I had the exact same problem. Checking the light revealed the light was ok. Cycling the gear did not cure the problem. Hand-cranking gave only 1/4 turn, and no change in the extinguished light. The previous time, was daylight, and a chase-plane observed the gear apparently down. Upon landing, the gear held up, and the light came on sometime during the landing rollout. The mechanic cycled the gear a number of times and declared it ok. My son had several lndgs ok, as did I, after the mechanic's work, and so I thought it was strange, but here was the same problem again. After slipping the aircraft to blow on the inside of the right main gear, proceeded to land, gently and slowly. After retracting the flaps, on rollout, right wing went down, scraped on runway, and aircraft slid off to the right of the runway. No injuries, minor damage. The right main gear push-pull rod had failed at gear's end.

Title: LNDG GEAR ON AN SMT COLLAPSES DURING A NIGHT OP LNDG.

Narrative: IN PREPARING FOR LNDG AT ONP, THE R MAIN GEAR LIGHT DID NOT LIGHT. SEVERAL WKS AGO, I HAD THE EXACT SAME PROB. CHKING THE LIGHT REVEALED THE LIGHT WAS OK. CYCLING THE GEAR DID NOT CURE THE PROB. HAND-CRANKING GAVE ONLY 1/4 TURN, AND NO CHANGE IN THE EXTINGUISHED LIGHT. THE PREVIOUS TIME, WAS DAYLIGHT, AND A CHASE-PLANE OBSERVED THE GEAR APPARENTLY DOWN. UPON LNDG, THE GEAR HELD UP, AND THE LIGHT CAME ON SOMETIME DURING THE LNDG ROLLOUT. THE MECH CYCLED THE GEAR A NUMBER OF TIMES AND DECLARED IT OK. MY SON HAD SEVERAL LNDGS OK, AS DID I, AFTER THE MECH'S WORK, AND SO I THOUGHT IT WAS STRANGE, BUT HERE WAS THE SAME PROB AGAIN. AFTER SLIPPING THE ACFT TO BLOW ON THE INSIDE OF THE R MAIN GEAR, PROCEEDED TO LAND, GENTLY AND SLOWLY. AFTER RETRACTING THE FLAPS, ON ROLLOUT, R WING WENT DOWN, SCRAPED ON RWY, AND ACFT SLID OFF TO THE R OF THE RWY. NO INJURIES, MINOR DAMAGE. THE R MAIN GEAR PUSH-PULL ROD HAD FAILED AT GEAR'S END.
