Things that aren’t boldface, but might as
well be:
T-44AT-44A
Transfer Pump Failure(possible “NO FUEL TRANSFER” light)
1) Check total and nacelle fuel quantity
If no fuel remains in wing tanks:
2) Transfer pump – OFF
If fuel remains in wing tanks and necessary to use otherwise trapped 28 gallons:
3) Transfer pump – OVERRIDE
If light remains on:
4) Transfer pump – OFF
NOTE: Consider altering flight plan; 28 gallons fuel trapped/unusable
5) Land as soon as practicable
T-44AT-44ABoost Pump Failure
(possible “FUEL CROSSFEED” light)* Failed boost pump is identified by momentarily placing the crossfeed
switch in the CLOSED position. The red LH or RH FUEL PRESSURE light will illuminate indicating the failed boost pump
1) Failed boost pump - OFF
2) Crossfeed - OPEN
NOTE: Determination of range with resorting to suction lift is dependent on fuel load remaining on the side opposite the failed boost pump (all fuel comes from tanks opposite failed boost pump).
3) Land as soon as practicable
* Above 13,000’, power loss will begin until fuel stabilizes due to pressure differential
* Suction lift limited to 10 hours between pump overhauls
T-44AT-44A
Fuel Siphoning
1) Airspeed – 140 KIAS
2) Land as soon as practicable
NOTE: Extreme nose-low attitudes will aggravate the fuel siphoning condition.
