(-23) The pilot stated in a post incident interview that he placed the landing gear in the down position prior to landing tvl. During rollout the pilot stated first the left main gear collapsed; shortly thereafter the right main gear collapsed; and then the nose gear collapsed. An inspection of the aircraft revealed that the gear selector was in the down position and the landing gear circuit breaker was open (popped). The left and right main landing gear were interconnected and could not operate independently. An inspection of the nose gear revealed that the retract/extend torque tube attach points were sheared from the nose landing gear assembly and were still attached to the torque tubes. The torque tubes (two each), which incorporate the landing gear switch striker arms, were bent in a compression load. The gear doors showed signs of skid damage. The above findings were reviewed with the aircraft manufacturer and it was determined that the damage addressed above was consistent with a landing with the landing gear in the retracted position and when the aircraft was on the ground, the landing gear selector was placed in the down position.
