3-8 FAA APPROVED 4-30-76
REISSUED 2-25-81, CHANGE 14
DUAL GENERATOR FAILURE
1. Electrical Load — Reduce.
a. COOL-FAN Switch — OFF.
b. AUX HT Switch (if installed) — OFF.
c. On aircraft incorporating AAK 86-1 or SB 35/36-21-17,
W/S AUX HEAT DEFOG Switch — OFF.
2. L and R IGN & ST Circuit Breakers (main power bus) — Check and
reset.
3. START-GEN Switches — GEN.
START-GEN switch must be in GEN for the respective
generator RESET switch to be effective.
4. GEN RESET Switches — Depress momentarily.
Depressing and holding the GEN RESET switch longer
than one-half second, or multiple activations, may cause
damage to the electrical system.
If Generators Do Not Reset:
5. Turbine Speed (N
2) — 80% RPM or above.
6. START-GEN Switches — OFF, then GEN.
7. GEN RESET Switches — Depress momentarily.
If Generators Do Not Reset:
8. START-GEN Switches — OFF.
9. JET PUMP Switches — Check, ON.
10. Both FUEL CMPTR Switches — OFF, one at a time. Control
engines manually.
• Engine response will be much slower with the fuel
computers OFF.
• Monitor Fan Speed (N
1) indicators. If an engine ac-
celerates uncontrolled, immediately set applicable
FUEL CMPTR switch(es) — On.
11. If there is fuel in the fuselage tank:
• Aircraft not equipped with FUS VALVE switch:
a. FUS TANK XFER-FILL Switch — XFER.
b. FUSLG PMP Circuit Breaker (copilot’s main bus) — Pull.
• Aircraft equipped with FUS VALVE switch:
a. FUS VALVE Switch — OPEN.
Approximately 162 pounds of fuselage fuel will be un-
usable.
12. Land as soon as practical.
