What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The instructor pilot stated that he was performing a simulated emergency over Los Banos airfield. The student pilot forgot to lower the landing gear. After the pilot made a turn towards the airfield he overshot the final approach course. At this time the instructor took over the flight controls but ignored the landing gear horn which was indicating that the gear was not lowered. The aircraft's propeller made contact with the runway surface followed by the aircraft skidding to a stop, resulting in a gear up landing.
