The airplane touched down on centerline and bounced. The pilot attempted to correct for the crosswind; however, the airplane touched down again and ground looped off the side of the runway. The wings and the empennage sustained substantial damage. The pilot reported that there were no mechanical anomalies that would have precluded normal operations. The reported wind at the time of the accident was from 350 degrees at 6 knots, gusting to 15 knots. ## Aircraft - Registration: [N795MB](https://openairdocs.org/deregistered/N795MB-2023-10-07), registration cancelled 2023-10-07, S/N 1720R (OpenAirDocs) - Reported make and model: AERO COMMANDER S2R - Registry model: [Aero Commander S2R](https://openairdocs.org/model/aero-commander-s2r) (registry code 0143022) (OpenAirDocs) - Category: Airplane - Serial number: 1720R - Airframe hours: 8703 - Engines: P&W R1340-S3H1G 600 horsepower reciprocating - Damage: Substantial damage - Flight: Aerial application, Part 137 - Operator: Marlow Aviation LLC - Registered owner: Marlow Aviation LLC - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, May 7, 2022, 10 hours before - Departed: EVU, Maryville, MO - Destination: Same as departure - Airport: EVU, Northwest Missouri regional, runway 14, 4,600 × 75 ft, concrete - Equipment: ADS-B, Satellite tracking device ## Flight crew As NTSB recorded them.
