During the second attempt, he utilized a technique that required flaps extended 10°, left wing down, and right rudder. The left main landing gear touched down first followed by the tailwheel as the pilot used full left aileron to counter the left crosswind. During the landing roll the airplane slid to the right and departed the runway. The airplane impacted a ditch and the main landing gear collapsed, which resulted in substantial damage to the right wing and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. At the time of the accident the wind was from 300° at 17 knots with gusts to 27 knots. ## Aircraft - Registration: [N3946K](https://openairdocs.org/aircraft/N3946K), registered now, S/N 24716 (OpenAirDocs) - Reported make and model: CESSNA L-19E - Registry model: [Cessna L-19E](https://openairdocs.org/model/cessna-l-19e) (registry code 2074016) (OpenAirDocs) - Category: Airplane - Serial number: 24716 - Year built: 1962 - Airframe hours: 5117 - Engines: Continental O-470-15 reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, February 8, 2022 - Departed: KDKB, Dekalb, IL - Destination: Same as departure - Airport: OSH, Wittman Rgnl, runway 36R, 6,300 × 50 ft, concrete - Equipment: Stall warning system, ADS-B, Electronic flight bag or handheld device, Onboard weather ## Flight crew As NTSB recorded them.
