What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot privacy data omitted (aircraft owner) and privacy data omitted were completing a maintenance check flight when the aircraft developed engine problems (loss of power). They immediately initiated a return to the airport while slowly gaining altitude. Upon approaching the airport, they performed the landing checklist. When the pilot realized he had not lost enough altitude to make a successful landing, the flight instructor suggested they perform a 360 degree right hand turn. Upon completion of the maneuver, the pilot made a landing with the gear in the up position. The flight instructor assured the pilot that the gear was in the down and locked position prior to touchdown. The pilot did not visually verify that the gear was in the down and locked position. Upon investigation, the landing gear was found to operate normally.
