A postaccident examination of the airplane revealed that the retract bellcrank on the left landing gear lower fork assembly fractured. The pilot reported that the landing gear was serviced during an annual inspection and the accident flight was the third flight after the landing gear was serviced. ## Aircraft - Registration: [N1668T](https://openairdocs.org/aircraft/N1668T), registered now, S/N 414-0461, built 1973 (OpenAirDocs) - Reported make and model: CESSNA 414 - Registry model: [Cessna 414](https://openairdocs.org/model/cessna-414) (registry code 2075908) (OpenAirDocs) - Registry engine: [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series) (registry code 17040, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 414-0461 - Year built: 1973 - Airframe hours: 4718 - Engines: Continental IO520 335 horsepower reciprocating; Continental IO520 335 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Kevu Aviators LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, August 25, 2025, 3 hours before - Destination: Same as departure - Airport: EVU, Northwest Missouri Regional, runway 32, 4,600 × 75 ft, concrete - Equipment: ADS-B, Auto-pilot, Stall warning system ## Flight crew As NTSB recorded them.
