NOTE
Before FARE fuel transfer begins, a path from
the desired ERFS II tank to the helicopter
main tanks must be established and the fuel
should be transferred from only one tank at a
time.
F 5. “T” couplings on ERFS II tanks not being
transferred — CLOSE.
CAUTION
There is no gauge on board the aircraft to
provide measurements of GPM or PSIG.
The rate at which fuel is transferred from
the ERFS II tanks to the Helicopter main
tanks is 20 GPM. The rate at which fuel is
transferred from the ERFS II tanks using
the FARE pump and standard FARE trans-
fer hose assembly is 84 to 88 GPM. The
FARE pump is rated at 120 GPM. Suction
defueling pressure should not exceed -11
PSIG. Do not exceed 5 PSI except in
extreme emergency. The ERFS II outer
container is expected to fail at 10 PSI or
greater. The crash resistant bladder will
prevent spillage and fuel can still be trans-
ferred.
F 6. FARE valve control handle OFF LOAD
Position.
F 7. FARE pump — ON.
F 8. ERFS II tank manually operated fuel/defuel
valve — OPEN.
F 9. Once ERFSII tank empties, tank fuel man-
ifold “T” coupling — CLOSE.
F 10. Next ERFS II tank fuel manifold “T”
coupling — OPEN.
F 11. Next/remaining ERFS II tank manually oper-
ated fuel/defuel valve — OPEN.
F 12. Once ERFS II tank empties, tank fuel man-
ifold “T” coupling — CLOSE.
F 13. FARE pump — OFF.
9-2-10. FARE Pump Failure During Ground FARE
Refueling Operation.
F 1. Filters — Remove.
F 2. Overwing nozzle — Install and use.
F 3. Manually operated fuel/defuel valves —
OPEN.
NOTE
If three ERFS II tanks are installed and all the
in-tanks are on, a 60 gallon per minute rate
can be achieved.
F 4. ERFS II tank pumps — ON.
9-2-11. EAPS 1 FAIL and/or EAPS 2 FAIL Caution
Light ON.
1. EAPS DOORS switch (affected engine) —
OPEN.
2. EAPS FAIL: caution capsule — Check out.
F 3. EAPS BYPASS DOORS OPEN light —
Verify light is ON.
