What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Aircraft N8074M touched down a Camarillo Airport with all three landing gears extended. During landing roll out on runway 26, the nose landing gear collapsed causing the airplane to pitch down on to the propeller, nose gear doors, and nose cowl. Camarillo operations officer found the airplane's gear handle in the up position. Propeller strikes on the runway indicate the the nose landing gear collapsed about 150 feet east of taxiway b with the aircraft coming to rest approximately 50 feet east of taxiway b. PIC stated in an interview on July 25th at the Camarillo Airport that he heard the landing gear horn just prior to the nose landing gear collapse. PIC also stated that his normal procedure was to raise the flaps on landing roll out. Photos of the airplane show the flaps extended, main landing gear doors opened, and right main landing gear unlocked and the aircraft at rest on the main gear and nose cowl. This particular airplane was not equipped with the optional landing gear safety system which incorporates two additional retract safety switches to prevent the gear from retracting on landing rollout.
