What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Aircraft owner/pilot: installed recently overhauled nosegear assembly. Installation required numerous gear actuation tests on jacks to determine proper operation and make any adjustments as necessary. After satisfactory tests were completed, owner/pilot removed the aircraft from jacks, entered the aircraft with his wife, and proceeded to runway 36 at Garberville Airport for departure. During the takeoff roll, the nosegear collapsed and the aircraft "ground looped." Minor damage to the right wingtip, belly of aircraft, lots of damage to the engine from ingestion of dirt, and damage to the propeller. Crankshaft runout shows no damage to the IO-320 (performed by lycon of visalia, CA). Cause of incident: owner/pilot began takeoff roll with the gear selector in the up position. Checklist did not have a "check of the gear position" prior to start or prior to takeoff. The checklist now incorporates this check.
