On the day of the accident, the three students jointly carried out a pre-flight inspection on 5N-CBE aircraft in preparation for the training exercise at 0800hrs. Thereafter, the students went to invite the instructor to carry out pre-flight inspection. On their return, they discovered that the aircraft (5N-CBE) had been towed away from the flight line by the maintenance engineers.
Another aircraft 5N-CBF was assigned for the training flight. Pre-departure inspection was also carried out on the newly assigned aircraft. At 1004hrs, the aircraft was airborne with five hours fuel endurance. The student was at the controls and the aircraft was cleared to 4000ft and to report maintaining.
