Hot Start AFM 3-11-40
If engine exceeds maximum start temperature (700°C):
1. HP Fuel Cock (Affected Engine) ............................................SHUT
2. Affected Engine........CONTINUE TO MOTOR FOR 30 SECONDS
Continue to motor the affected engine for a maximum of thirty
(30) seconds to reduce TGT.
After a maximum of thirty (30) seconds:
3. START MASTER ......................................................................OFF
Prior to the next attempt to start, check that the fuel boost pump is
ON, fuel pressure is normal, an air source is available and its pressure
is adequate. Check wind direction and attempt to start directly into the
wind; move the airplane if required. If a second attempt produces a
hot start, shut down the affected engine. DO NOT attempt a restart.
