During the takeoff and landings, the wind was from the northwest at 8 to 11 knots with no wind gusts. After approximately 0.7 hours of flight time, the certified flight instructor exited the airplane and the student pilot taxied to the runway for takeoff. About the time of departure, the wind began to gust to 17 knots. The student pilot stated that during the landing flare, he experienced a downwash and that the airplane ballooned and turned to the right. He added power and applied rudder, but the nosewheel hit the runway and the airplane veered off the runway. The certified flight instructor placed a maximum wind limitation of 15 knots on the student pilot's initial solo endorsement. ## Factual narrative The student pilot and his certified flight instructor performed three takeoff and landings at the accident airport in preparation for the student pilot's second solo flight. During these three takeoff and landings, the winds were from the northwest at 8 to 11 knots with no wind gusts. After approximately 0.7 hours of flight time, the certified flight instructor exited the airplane, and the student pilot taxied to runway 28L for takeoff. About the time of departure, the winds began to gust to 17 knots. The student pilot stated that during the landing flare on runway 28L, he experienced a "downwash" and the airplane "ballooned and turned to the right." The student pilot added "some power" and applied rudder, but the nose wheel hit the runway and the airplane veered off the runway. The certified flight instructor placed a maximum wind limitation of 15 knots on the student pilot's initial solo endorsement. ## Aircraft - Registration: [N9253S](https://openairdocs.org/aircraft/N9253S), registered now, S/N M-1750, built 1975 (OpenAirDocs) - Reported make and model: BEECH C23 (NO SERIES) - 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-1750 - Airframe hours: 4371 - Engines: Lycoming O-360-A4K 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Inflight Pilot Traning LLC - Registered owner: Mark Ward Aviation LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 17, 2010 - Departed: FCM, Eden Prarie, MN - Destination: FCM, Eden Prarie, MN - Airport: FCM, Flying Cloud Airport, runway 28L, 5,000 × 100 ft, asphalt ## Flight crew As NTSB recorded them.
