Incident Description
During a training flight, the crew performed a touch-and-go landing on Runway 17. The final approach was described as steep, flown with full (45°) flap. After a short ground roll, the pilot under training advanced the throttles and rotated the aircraft at about 80 knots, with the flaps still at the full 45-degree setting.
Sequence of Events
Shortly after becoming airborne, a loss of power occurred, accompanied by vibration or buffeting. The aircraft yawed and rolled to the right, and airspeed began to decay. The pilot under training then retracted the flaps to 30°, at which point the instructor took control, closed the throttles, and landed the aircraft on the grass on a heading of approximately 200° magnetic.
The aircraft continued across the southwestern taxiway, through the airfield perimeter fence, across a public road, where the undercarriage collapsed, and finally came to rest in an adjacent field. Both fuel tanks were ruptured by impact with fence posts, but there was no fire.
Outcome
The crew, who were uninjured, shut off the fuel cocks, switched off the electrical systems, and vacated the aircraft through the main entry door. Emergency services responded quickly and arrived at the scene by the time the crew exited the aircraft.
