What was found
MLG: AIRCRAFT WAS BEING TOWED INTO A HANGAR BY THE PORT OF EPHRATA AIRPORT. WHILE THE AIRCRAFT WAS BEING PUSHED BACK THE RIGHT MAIN LANDING GEAR WAS ROLLED BACK ONTO SOME WOOD PLANKS THAT COLLAPSED CAUSING THE RIGHT GEAR TO SINK INTO THE GROUND ABOUT A FOOT. THE RIGHT WING DID NOT CONTACT THE GROUND. WE DID ASK IF THEY NEEDED ANY HELP BEFORE TOWING THE AIRCRAFT BUT OUR ASSISTANCE WAS DECLINED AND WE WERE NOT PRESENT DURING THE TOW. THE ONLY DAMAGE THAT WAS VISIBLE TO US WAS THAT THE RIGHT MAIN GEAR DOOR APPEARS TO HAVE BEEN BENT DURING THE COLLAPSE. CORRECTIVE ACTION: REPLACED LH & RH MLG DOOR ASSY. OPS CHECK GOOD. IAW AMM 32-10-00.
