From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

This accident occurred in the traffic pattern foot print of Lincoln regional (lhm) airport Lincoln, CA. This was a FAR 91, personal local flight with one pasenger. The aircraft has a special airworthiness certificate in the experimental category for the purpose of operating a light sport airplane, originally issued 1/26/2008 and amended 1/21/2010.the privacy data omitted of the aircraft was issued his privet pilot certificate 5/7/2005 and had logged 378 hours total time in single engine land airplanes. His last biannual flight review documented in his log book is dated 5/21/2009. He has a third class medical issued 1/22/2008. His last logbook entry is dated 7/1/2009.a witness who is a pilot with experience in similar aircraft observed the event. He stated he observed the aircraft approach the airfield on a left 45 to down wind to runway 15. He said there was another aircraft in the pattern. He saw N1901C make a turn to the left (apparently to do a 360 turn to allow spacing between him and the other aircraft in the pattern) approximately 180 into the turn the left wing dipped down and the aircraft spun in and impacted the ground. The aircraft was substantially damaged when it struck the ground in a nose down left hand attitude. Both aircraft doors had been remover before the flight. The left hand wing was removed by first responders to gain access to the fatally injured occupants. Therefore fuel quantity in that tank is unknown. The right hand fuel tank was intact with 4 gallons of fuel recovered. Flight control continuity was established for the rudder. The elevator control from behind the seats back to the tail was intact, from that area forward was smashed in impact. Aileron control system in the wings was damaged and crushed in the belly of the aircraft but the hardware and linkages would lead one to believe it was functioning. I was unable to tell if the flaps had been extended due to damage to the system. One propeller blade was severed at the hub the other had blade tip damage. NTSB file number is WPR10LA293.
