Narrative:

During rollout after landing; at taxi speed left gear collapsed then right gear and nosewheel. Gear handle in down and locked position. Gear light green and all checklists completed. Callback conversation with reporter revealed the following information: during the approach and landing the landing gear lever was in the down and lock position and the landing gear position indication was a single green light illuminated indicating down and locked. The airplane was at taxi speed at end of rollout and just about ready to turn onto a taxiway when the left main landing gear collapsed followed by the right main landing gear and nose landing gear. Before exiting the airplane the landing gear lever was observed still in the down and locked position. The FAA has investigated and did not appear at all concerned about the failure mode and classified the occurrence as an incident. Damage was incurred to both engines and propellers and some minor belly skin scrapes. The airplane has not been jacked to determine the cause of the gear failure and everyone is waiting for the insurance company action.
