NTSB narrative
ON SUNDAY 1/27/85 AT APPROXIMATELY 0849 MST, A BEECH DUCHESSN1850S, ON LEASE TO THE UNIVERSITY OF NORTH DAKOTA CRASHED AFTER TAKEOFF FROM THE GRAND FORKS AIRPORT, GRAND FORKS, ND.THE STUDENT PILOT AND CERTIFIED FLIGHT INSTRUCTORE WERE NOT INJURED. TWO PASSENGERS IN THE BACK SEATS RECEIVED SERIOUS INJURIES. THERE WAS NO FLIGHT PLAN FILED AND VMC PREVAILED. THE PRELIMINARY INVESTIGATION REVEALED THAT THIS FLIGHT WAS A TRAINING FLIGHT IN A MULTI-ENGINE AIRCRAFT. THE STUDENT PILOT INITIATED THE FLIGHT ON RUNWAY 34R. AT AN ALTITUDE OF APPROXIMATELY 150 FT. ABOVE GROUND LEVEL (AGL) THE FLIGHT INSTRUCTOR SIMULATED AN ENGINE FAILURE RETARDING THE LEFT THROTTLE. THE STUDENT PILOT WAS SLOW TO REACT TO THE FAILURE AND THE AIRSPEED DROPPED BELOW VMC. THE FLIGHT INSTRUCTOR TOOK CONTROL OF THE AIRCRAFT AND ATTEMPTED TO REGAIN FLYING SPEED BY INCREASING BOTH ENGINES TO FUEL POWER. THE INSTRUCTOR WAS UNABLE TO REGAIN AIRSPEED BEFORE GROUND IMPACT.

Source notes (5)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
- API snapshot SHA-256: 4d6839be32983f1b89cc7b7ae082a47f04480ba6ada3d4d92537cac59f0c5f29; retrieved 2026-09-21T17:21:46.663Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: departure. The narrative states the airplane "CRASHED AFTER TAKEOFF FROM THE GRAND FORKS AIRPORT, GRAND FORKS, ND"; the departure was not recorded.
