The pilot commenced the take-off run and confirmed that full power was selected. At an indicated airspeed of 90 knots, he rotated the aircraft and waited for the performance instruments to indicate that a positive rate of climb and the single engine climb speed had been achieved. The pilot reported that the aircraft did not accelerate beyond an airspeed of 95 knots and a positive rate of climb was not obtained. He stated that he retracted the gear, to avoid having it snag the boundary fence, and then realised that the left engine was losing power and altitude was not being maintained. The pilot then closed the throttles and the aircraft landed in open country beyond the aerodrome boundary. An inspection of the aircraft did not detect any faults in the engines or other aircraft systems that could have contributed to the occurrence. An examination of the propellers indicated that both engines were delivering power at the time the aircraft struck the ground. The cause of this accident remains undetermined.
