Incident Overview

Description
During a training flight, a no. 2 engine failure was simulated. The student pilot feather the propeller and continued the approach for a full stop landing. On finals the gear was raised and engine power increased. The aircraft rolled to the right and impacted the runway with its right wingtip and right hand main gear leg. The Caribou skidded off the runway for some 220 m, crashed across a drainage ditch and through a barbed wire fence. PROBABLE CAUSE: “Strong asymmetric thrust caused by increasing engine power on the operative engine when the aircraft was about to touch down with one engine feathered. Contributing factors were: 1) the lack of understanding between the two flight crew members of what each other was doing immediately prior to the accident; 2) the student/instructor relationship between the two and the prevailing dark night-time conditions.”
