When the pilot got out of the plane, the engine compartment and the hood were in flames already. The people standing around the aircraft attempted to extinguish the fire by portable fire extinguishers, but they were unsuccessful. Then they moved the burning aircraft away from the vicinity of other aircraft with the help of a rope attached to the tail of the aircraft in order to prevent propagation of the fire. The aircraft burnt out in the occurrence, but no one was injured.
Causes of the occurrence:
The IC concluded through the investigation that the immediate cause of the occurrence was as follows:
- as a consequence of a short circuit, the high power cable began to glow and split up in such manner that its falling pieces were able to ignite combustible materials both in the engine compartment and in the cockpit.
The root cause behind the immediate cause:
- A short circuit occurred at the passage of the high power cable through the firewall.
- the maximum ambient temperature was unusually high, 41°C (106°F) on the day of the occurrence, which was favourable for the development and rapid spread of the fire in the airplane.
