The pilot stated the aircraft cabin door came unlatched shortly after takeoff. The pilot chose to return to the departure airport for landing on Runway 12 (3,133 feet by 75 feet, asphalt). He reported that the aircraft touched down on the left main gear, with a "slight drift." The left main gear subsequently collapsed. The aircraft came to rest approximately 1,000 feet down the runway and about 30 feet off the left side of the pavement. The pilot noted a "series of distractions" prevented him from concentrating on a safe landing.
