Probable cause & findings

POOR IN FLIGHT PLANNING AND DECISION MAKING BY THE FLIGHT INSTRUCTOR IN ALLOWING THE STUDENT TO PROGRESS TO A POINT WHERE A SAFE FLIGHT REGIMEN COULD NOT BE MAINTAINED. A FACTOR WAS: THE DUAL STUDENTS FAILURE TO MAINTAIN CONTROL OF THE AIRCRAFT.

Factual narrative

DURING THE LANDING PHASE, AFTER CONDUCTING A SIMULATED SINGLE ENGINE APPROACH, THE STUDENT FAILED TO MAINTAIN CONTROL OF THE AIRCRAFT. THE INSTRUCTOR TOOK CONTROL AND DURING THE ATTEMPTED GO AROUND THE AIRCRAFT STRUCK SEVERAL SNOW BANKS AND THEN BECAME AIRBORNE. CONTACT WITH THE SNOW BANKS CAUSED DAMAGE TO ALL THREE LANDING GEAR AND BOTH PROPELLERS. AFTER ORBITING FOR APPROXIMATELY TWO HOURS AND FIFTY MINUTES, TO BURN OFF FUEL, AN EMERGENCY LANDING WAS MADE WHICH CAUSED DAMAGE TO THE LEFT TIP TANK, NOSE SECTION, AND MAIN FUSELAGE.
