Fuel System Malfunctions
B. Verifications
1. No secondary indications
2. No verification possible
NOTE: Assume that a malfunction has occurred whenever the
primary indications occur.
C. Effects on flight safety
1. Fuel to engine maintained by LP pump suction via boost pump
bypass valve
2. Negative-g maneuvers may cause the engine to flame out
III. Fuel leaks 1.8.1.2.1.1
A. Indications
Fig 2: Fuel Quantity
Indicator
1. Fuel quantity indicator reads significantly lower than planned fuel
consumption
2. Wingman or other aircraft notices vapor trail
B. Verifications
1. No test for fuel gauge accuracy
2. If gauge indicates leak, get visual verification from cockpit or other
aircraft
NOTE: Lack of visual verification does not nullify the possibility of a
leak. A leak could be more serious if it’s not visible because it
might be at the engine.
C. Effects on flight safety
1. Rate of loss significant: immediate emergency if fuel loss is
excessive
2. If leak is near engine, be aware of fire hazard
3. Possible flameout
