The defining event best describes what happened. - [Takeoff: Dynamic rollover](https://openairdocs.org/ntsb-events/231) (defining event); cases with it: [Robinson Helicopter R22 BETA, 35 cases](https://openairdocs.org/ntsb-events/231/sequence.md?model=7640110), [All aircraft, 161 cases](https://openairdocs.org/ntsb-events/231/sequence.md) ## Analysis The certified flight instructor (CFI) was providing instruction to the student pilot, who had 3 hours of total flight time. The student pilot was practicing takeoffs and landings. During an attempted takeoff, the left skid did not lift off and the helicopter experienced a dynamic rollover, which is when the helicopter pivots about the skid remaining on the ground and enters a rolling motion that cannot be corrected with full lateral cyclic input. The helicopter rolled over on its left side and sustained substantial damage to its primary fuselage structure. The operator of the helicopter reported that at the time of the accident the student pilot had not learned how to hover. According to the company’s flight training syllabus, the CFI should not have been providing instruction in takeoffs and landings until the student pilot was able to safely hover the helicopter. ## Factual narrative The certified flight instructor (CFI) was providing instruction to the student pilot who had 3 hours of total flight time. The student pilot was practicing “pickups and set downs.” During an attempted pickup, the left skid did not lift off, and the helicopter experienced a dynamic rollover. The helicopter rolled over on its left side and sustained substantial damage to its primary fuselage structure. The operator of the helicopter reported that at the time of the accident, the student pilot had not learned how to hover. According to the company’s flight training syllabus, the CFI should not have been providing instruction in pickups and set downs until the student pilot was able to safely hover the helicopter. ## Aircraft - Registration: [N7195B](https://openairdocs.org/deregistered/N7195B-2017-03-06), registration cancelled 2017-03-06, S/N 3159, built 2001 (OpenAirDocs) - Reported make and model: ROBINSON HELICOPTER R22 BETA - Registry model: [Robinson Helicopter R22 BETA](https://openairdocs.org/model/robinson-helicopter-r22-beta) (registry code 7640110) (OpenAirDocs) - Registry engine: [Lycoming 0-360-A1D](https://openairdocs.org/engine/lycoming-0-360-a1d) (registry code 41504, reciprocating) (OpenAirDocs) - Category: Helicopter - Serial number: 3159 - Airframe hours: 2738 - Engines: LYCOMING 0-360-A1D 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Complete Helicopters Inc - Registered owner: Complete Helicopters Inc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, January 28, 2011 - Departed: ANE, Anoka, MN - Destination: ANE, Anoka, MN - Flight plan: Unknown - Airport: ANE, Anoka County - Blaine Airport ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
