NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
A dual student initiated a short field takeoff on runway 28. As the airplane neared rotation speed, it encountered a large patch of ice and started to drift left. The student pilot aborted the takeoff, and directional control was recovered. When the student pilot applied rudder to return to the center of the runway, the airplane again drifted left until it was into the snow at the left edge of the runway. The airplane then nosed over onto its back. The flight instructor reported that he coached the student, but did not take control of the airplane. About 25 percent of the runway surface was reported to be covered with ice, with more ice on the first 1/3 of the runway. No evidence of a malfunction with the flight controls, wheels, or brakes was found. The wind was reported as 290 degrees at 15 knots. Runway 28 was 4242 feet long and 75 feet wide.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: failure of the flight instructor to adequately supervise the dual student pilot and ensure that directional control of the airplane was maintained. The icy runway was a related factor. Full narrative available
