The defining event best describes what happened. - [Landing-flare/touchdown: Landing gear not configured](https://openairdocs.org/ntsb-events/095) (defining event); cases with it: [Cessna 172RG, 15 cases](https://openairdocs.org/ntsb-events/095/sequence.md?model=2072438), [All aircraft, 584 cases](https://openairdocs.org/ntsb-events/095/sequence.md) ## Analysis During an instructional flight, the flight instructor requested that the student pilot, a commercial rated pilot in the right seat, demonstrate a simulated emergency engine-out landing. The student reduced the throttle to idle, turned toward the runway, and completed the GUMPS (gas, undercarriage, mixture, propeller, seat belt and switches) checklist. The student announced that he would not lower the landing gear and flaps until the runway was assured. Once established on centerline, a final check was not completed, and the student made a gear-up landing. The lower fuselage was substantially damaged. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation. ## Factual narrative During an instructional flight, the flight instructor requested that the student pilot, a commercial rated pilot in the right seat, demonstrate a simulated emergency engine-out landing.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
