If an engine fire is observed with the engine not running, the following
action should be taken:
1. Close the fuel valve switch positioned on left side of the cockpit,
forward of the Bugwiper switches (optional).
2.
Move the Jet Control toggle switch to “EXT” position. Do not retract
the engine.
3. During the cooling cycle air will be forced through the turbine, also
forcing the flames to exit at the exhaust. It is important to keep the
air flowing through the turbine, either with the starter motor or by
external high-pressure air.
4. Wait until all excess fuel inside the turbine is burnt.
5. Do not retract the engine while hot or while any flames are visible.
If an engine fire spreads into the fuselage area, it is regarded as a
hazardous situation and immediate action is required:
1. Close the fuel valve switch positioned on the left console.
2. If the engine is not fully extended and the engine bay doors are
open, extend engine immediately to close the bay doors by moving
the Jet Control toggle switch to “EXT” position.
3. Use an aircraft type fire-extinguisher to extinguish the fire.
4. Do not retract the engine while hot or while any flames are visible.
5. Allow the engine to cool down completely before further
investigation is initiated.
6. Ensure the aircraft is serviceable before commencing with further
flying.
