The defining event best describes what happened. - [Landing: Aerodynamic stall/spin](https://openairdocs.org/ntsb-events/241) (defining event); cases with it: [Cessna 177B, 5 cases](https://openairdocs.org/ntsb-events/241/sequence.md?model=2073708), [All aircraft, 1,529 cases](https://openairdocs.org/ntsb-events/241/sequence.md) ## Analysis The pilot reported that while on final approach, he was losing altitude faster than expected and the airspeed was slow. He added power so he could make the runway. The airplane subsequently pitched up, and the pilot lost sight of the runway. He added power and pitched the airplane’s nose down in an attempt to avoid a stall. As soon as he pitched the nose down, the airplane impacted the ground. The airplane came to rest inverted, and the right wing and vertical stabilizer sustained substantial damage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N30853](https://openairdocs.org/aircraft/N30853), registered now, S/N 17701504, built 1970 (OpenAirDocs) - Reported make and model: CESSNA 177B - Registry model: [Cessna 177B](https://openairdocs.org/model/cessna-177b) (registry code 2073708) (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: 17701504 - Year built: 1970 - Airframe hours: 2369 - Engines: Lycoming O-360 A1F6 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Quad City Area Flying Eagles Inc - Registered owner: Quad City Area Flying Eagles Inc - Airworthiness certificate: Standard, Normal; Standard, Transport - Last inspection: Annual, August 16, 2024 - Departed: M17, Bolivar, MO - Destination: MO06, Shell Knob, MO - Airport: MO06, Discovery Bay Airport at Norwalk Landing, runway 020, 1,900 × 50 ft, asphalt - Equipment: ADS-B, Stall warning system ## Flight crew As NTSB recorded them.

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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
