conditions that are acceptable to aircraft operations.
Installing the non-crashworthy ERFS
Therefore, the number of personnel on
board the aircraft will be kept to the
personnel are required to be seated with
a lap belt during flight.
EMERGENCY PROCEDURES. The ERFS is a
system designed with redundant capabilities to ensure
system reliability in flight.
In the event of an inflight fuel leak due to a
manifold seal malfunction the dust cover seal can be
used to replace the manifold seal.
Leaks in the ERFS fuel manifold system can be
isolated by using the coupling shutoff characteristics.
Failure of pumps. If both pumps feeding one
side of the aircraft fail (pumps 1 and 2), use these
(1) Place the override switch in the ON position.
(2) If pumps 1 and 2 are still inoperative, turn
them OFF. Continue pumping operations with pumps 3
and 4 until all ferry fuel is transferred. Since fuel is only
being pumped to one side of the aircraft, fuel
management via the cross-feed method will be required.
(3) Repeat procedure in same manner if pumps
3 and 4 were to fail.
If pump switch fails to stay ON in flight, check to
see that the FMCP pump circuit breaker is in and turn
the override switch on. If the pump switch still fails to
stay ON, turn the effected pump OFF. If all pump
switches fail, abort mission.
