Narrative:
The pilot attempted three times to start the aircraft’s engine, but without success. The pilot then called the safety pilot of the training school who advised him to wait for about five minutes to avoid over flooding the engine. About five minutes later, the pilot tried to start the engine again, but the engine still did not respond. To prevent draining the battery, the pilot switched off the master switch for a few minutes. Moments later, the pilot and the passenger saw smoke coming from the engine cowlings and they both disembarked the aircraft. As soon as they disembarked the aircraft, they saw flames emanating from the engine compartment. The fire was successfully extinguished by the pilot using the on-board hand-held Halon fire extinguisher.
The aircraft sustained fire damage to the engine compartment and the paint work on the cowlings. The pilot and the passenger did not sustain any injuries during the accident.

The cause of fire was due to over priming the engine, which led to fuel flooding the cylinder heads which were still hot, and thus, ignited the fuel.
