Probable cause
Inadequate supervision by the flight instructor. Factors related to the accident were: failure of the student pilot to attain a proper touchdown point, his delay in configuring the aircraft & executing the go-around, icy/snowy runway conditions, and the snowbank.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The CFI said the student plt was at the controls & was making a touch-&-go landing on rwy 12, which was 2800 x 50 ft. the wind was from the south at 10 KTS. The trainee landed long, & by the time the acft was reconfigured for takeoff, only about 800 ft of rwy was remaining. The CFI thought the trainee would stop & taxi back for takeoff; however, the trainee advanced the throttle for takeoff. At that time, the CFI took the controls, closed the throttle & attempted to stop. The acft slid to the left on the packed snow & ice covered rwy, collided with a snow bank beside the rwy & nosed over.
