The defining event best describes what happened. - [Landing-flare/touchdown: Abnormal runway contact](https://openairdocs.org/ntsb-events/090) (defining event); cases with it: [Beech C23, 7 cases](https://openairdocs.org/ntsb-events/090/sequence.md?model=1151242), [All aircraft, 1,506 cases](https://openairdocs.org/ntsb-events/090/sequence.md) ## Analysis The pilot reported that during the landing flare, the airplane seemed to lose lift and the airplane bounced three times on the runway. The nose landing gear collapsed which resulted in substantial damage when the lower engine mount bolts pulled part of the fuselage attaching structure through the firewall. There were no mechanical anomalies with the airplane that would have precluded normal operations. ## Aircraft - Registration: [N711DM](https://openairdocs.org/deregistered/N711DM-2023-09-16), registration cancelled 2023-09-16, S/N M-1403, built 1972 (OpenAirDocs) - Reported make and model: BEECH C23 - Registry model: [Beech C23](https://openairdocs.org/model/beech-c23) (registry code 1151242) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: M-1403 - Year built: 1972 - Airframe hours: 3658 - Engines: Lycoming O-360-A46 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 1, 2022 - Destination: Same as departure - Airport: K15, Grand Glaize-Osage Beach, runway 15, 3,205 × 60 ft, asphalt - Equipment: Auto-pilot, Stall warning system ## Flight crew As NTSB recorded them.
