Both pilots were flight instructors. The supervising instructor was in the front seat. The instructor looking to gain experience was in the rear seat. The pilots began by conducting two touch and goes on the turf runway without incident. However, as more aircraft entered the traffic pattern for the intersecting paved runway they decided to use that runway. The initial approach and flare to that runway, 13 (4,300 feet by 75 feet, asphalt), were stable. After touchdown the airplane drifted to the left. As the rear seat (flying) pilot attempted to correct, the airplane veered to the right, departing the right side of the runway and nosing over. The supervising instructor reported that there were no failures or malfunctions associated with airplane prior to the accident. ## Factual narrative The purpose of the instructional flight was to gain experience in flying the tail wheel configured airplane from the rear seat.

As the rear seat (flying) pilot attempted to correct, the airplane veered to the right. It subsequently departed the right side of the runway and nosed over. The supervising instructor reported that there were no failures or malfunctions associated with airplane prior to the accident. The supervising instructor reported having accumulated a total flight time of 1,497 hours, with 3 hours in the same make and model airplane. The rear seat (flying) pilot reported a total flight time of 377 hours, with 2 hours in the same make and model. Winds were from 270 degrees at 5 knots. ## Aircraft - Registration: [N18ND](https://openairdocs.org/aircraft/N18ND), registered now, S/N CC18-0004, built 2005 (OpenAirDocs) - Reported make and model: CUB CRAFTERS CC18-180 - Registry model: [Cub Crafters CC18-180](https://openairdocs.org/model/cub-crafters-cc18-180) (registry code 2470001) (OpenAirDocs) - Registry engine: [Lycoming O-360 series](https://openairdocs.org/engine/lycoming-o-360-series) (registry code 41575, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: CC18-0004 - Airframe hours: 480 - Engines: LYCOMING O-360 SERIES 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Und Aerospace Foundation - Registered owner: Und Aerospace Foundation - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, August 7, 2008 - Departed: CKN, Crookston, MN - Destination: CKN, Crookston, MN - Flight plan: Unknown - Airport: CKN, Crookston Muni, runway 13, 4,300 × 75 ft, asphalt ## Flight crew As NTSB recorded them.
