CAUTION
Do not attempt engine airstarts above 25,000 ft.
As engine accelerates to idle speed, it may be-
come necessary to move the condition lever into
FUEL CUTOFF in order to avoid an overtemper-
ature condition.
1. POWER lever — IDLE.
2. PROP lever — HIGH RPM.
3. CONDITION lever — FUEL CUTOFF.
4. FIRE PULL handle — (PUSH TO EX-
TINGUISH annunciator extinguished).
5. Engine anti-ice — Off.
6. GENERATOR switch (inoperative engine) —
OFF.
7. Airspeed — As required (140 knots propeller
windmilling, 190 knots propeller feathered).
8. Altitude — Below 25,000 feet.
9. Engine N1 — Monitor (10% minimum, propel-
ler feathered).
NOTE
N1 may be increased by increasing airspeed.
10. AUTO IGNITION switch — ARM.
11. CONDITION lever — LOW IDLE.
12. Power — As required (after TGT peaks).
13. GENERATOR switch — RESET, then ON.
14. Engine cleanup — Perform if engine start was
unsuccessful.
15. PROP SYNC switch — As required.
16. Electrical equipment — As required.
17. CONDITION lever — HIGH IDLE.
18. Cabin air mode switch — As required.
9-10. ENGINE RESTART DURING FLIGHT (USING
STARTER).
WARNING
Airstarts using the starter assist procedures will
momentarily cause the loss of all electronic flight
instrument system (EFIS) data. The engine re-
start during flight (no starter assist procedure), or
turning EFIS power off prior to a starter assisted
restart, should normally be performed.
Engine restarts should only be attempted below
25,000 feet. If a restart is attempted, perform the follow-
ing:
CAUTION
The pilot should determine the reason for engine
failure before attempting an airstart. Do not at-
tempt an airstart if N1 indicates zero.
Do not attempt engine airstarts above 25,000
feet. During engine acceleration to idle speed, it
may become necessary to move the CON-
DITION lever into FUEL CUTOFF in order to
avoid an overtemperature condition.
1. CABIN AIR MODE SELECT switch — OFF.
2. FWD VENT BLOWER switch — AUTO.
3. AUTO PLT POWER switch — Off.
4. EFIS POWER switches (2) — OFF (if condi-
tions permit).
NOTE
If EFIS power is turned off, aircraft attitude
should be maintained by using outside visual
references or the air driven standby attitude indi-
cator and turn-and-slip indicator.
5. Radar — SBY or OFF.
6. POWER lever — IDLE.
7. PROP lever — Low RPM.
8. CONDITION lever — FUEL CUTOFF.
9. FIRE PULL handle — Push in (to extinguish
annunciator).
NOTE
If conditions permit, reduce power on the opera-
tive engine to obtain a TGT of 700 C or less to
reduce the possibility of exceeding TGT limit.
Reduce electrical load to minimum consistent
with flight conditions.
False fuel flow indications may be observed with
the starter engaged and the CONDITION lever
in FUEL CUTOFF.
10. ENG START switch — START-IGNITION.
Check IGN ON annunciator illuminated.
11. CONDITION lever — LOW IDLE.
