SDS checklist question - engine fire during start- or after running (hypothetical)
The OP and commentors so far addressed the potential for a fire during the start process - most likely in the induction system (intake/throttle body/filter/snorkel). The Checklist item for this could look something like this;
1/ engine fire during start -
fuel pumps [OFF], continue cranking STARTER with FULL Throttle, fuel valve [CLOSE], electrics SDS MASTER [OFF]...
But what if the engine started and is running, & suddenly there are flames licking out the sides of the cowling? The steps would be different;
2a/ fire while engine is running on ground - fuel pumps [OFF], fuel valve [CLOSED], throttle [CLOSE], electrics- SDS master [OFF] - Master [OFF], employ fire extinguisher through lower cowl air exit into engine compartment as necessary.
2b/ engine fire in flight - f/p [OFF], f/valve [CLOSED], throttle [CLOSED], SDS master [OFF] - Master [OFF], FLIGHT ATTITUDE, dive the plane as necessary to starve the fire, prepare for emergency landing.
It is important to make the distinction between a start fire (probably in the induction system)compared to a running engine fire (outside the engine- most likely an electrical or fuel leak caused).
