SHP) EMERGENCY PROCEDURES
FUEL SYSTEM MALFUNCTIONIINADVERTENT
FUEL FLOW INTERRUPTION PROCEDURES
Fuel flows by gravity from the wing tanks, through fuel tank shutoff
valves at the inboard end of each wing tank, and on to the reservoir
located under the center cabin floorboard. after engine start, the main
ejector pump (located in the reservoir) provides fuel to the
engine-
driven fuel pump at approximately
10
psi.
If the main ejector pump should malfunction, a pressure switch will
activate the amber FUEL PRESS LOW annunciator as well as turn on
the auxiliary boost pump (when the fuel boost switch is in the NORM
position) anytime the fuel pressure drops below approximately
4.75
psi.
Anytime the level of fuel in the reservoir drops to approximately
one-
half full, the red RESERVOIR FUEL LOW annunciator will illuminate. If
this occurs, the pilot should immediately verify that both fuel tank
selectors (located in the overhead panel) are-ON and turn on the
ignition and fuel boost switches.
WARNING
THERE IS ONLY ENOUGH FUEL IN THE RESERVOIR
FOR APPROXIMATELY
1-112
MINUTES OF ENGINE
OPERATION AT MAXIMUM CONTINUOUS POWER
AFTER ILLUMINATION OF THE RESERVOIR FUEL LOW
If the fuel tank selectors have been left off, turning them on will quickly
fill the reservoir and extinguish the RESERVOIR FUEL LOW
annunciator. Once the cause of the RESERVOIR FUEL LOW condition
has been determined and corrected (annunciator extinguished), the
ignition and fuel boost switches can be returned to their NORM
positions.
