Narrative:
The aircraft was an experimental retractable tricycle gear; single engine; 2 seats. [The event followed] a completely normal 30 minute flight. Touchdown was at about 75 KTS and 'firm'; but not hard. We immediately heard a popping noise and the right main gear collapsed. This was immediately followed by the left main and then the nosewheel [collapsing]. We skidded about 50 yards on the runway; then off the ride side onto the grass; shearing off one runway light in the process (which caused a small fuel leak in the left wing.) the aircraft came to a rest upright; no fire; no injuries to either occupant. Damage confined to prop; belly; gear assemblies; and left wing so far as we know; (engine suffered sudden stoppage); and the runway light. Local personnel very quick and helpful to secure the airplane and later to move it to a locked hangar.
