TM 1-1510-262-10
Monitor TGT to avoid a hot start. If there is a rapid rise in TGT, be prepared to abort the start before
limits are exceeded. During starting, the maximum allowable TGT is 1000C for 5 seconds. If this
limit is exceeded, initiate Abort Start procedure and discontinue start. Enter the peak temperature
and duration on DA Form 2408-13-1.
5.
TGT and N 1 -- Monitor (TGT 1000C maximum).
6.
Oil pressure -- Check (60-PSI minimum).
ENG START switch -- OFF after TGT peaks.
7.
CONDITION lever -- HIGH IDLE . Monitor TGT as CONDITION lever is advanced.
8.
GENERATOR switch -- RESET , then ON.
9.
*8-16. SECOND ENGINE START (BATTERY START).
1. GENERATOR DC LOAD -- Verify 50% or less.
2. Propeller area -- Clear.
3. ENG START switch -- START-IGNITION. IGN ON annunciator should illuminate and FUEL PRESS
annunciator should extinguish.
4. CONDITION lever (after N 1 RPM stabilizes above 13% minimum) -- LOW IDLE.
5. TGT and N 1 -- Monitor (TGT 1000C maximum on the starting engine, TGT 750C maximum on
the engine already running).
6. Oil pressure -- Check (60-PSI minimum).
7. ENG START switch -- OFF after TGT peaks.
8. CONDITION levers -- HIGH IDLE. Monitor TGT as CONDITION lever is advanced.
Monitor oil temperature closely during ground operation with propellers in FEATHER due to lack of
airlow over oil cooler.
9. PROP levers -- HIGH RPM.
10. #1 and #2 INVERTER switches -- ON , check INVERTER annunciators OFF.
11. Current limiters -- Check as follows:
a. BATTERY CHARGE annunciator -- Check on. BATTERY CHARGE annunciator should extinguish
within 5 minutes following a normal engine start on battery. If light is extinguished, check that
no discharge condition exist.
b. #1 and #2 INV annunciators -- Check extinguished. This procedure checks both 400 and
500-ampere current limiters that tie aircraft bus systems together.
12. GENERATOR switch -- RESET , then ON.
NOTE
To reset beacon light, turn OFF for approximately 5 seconds, then DAY or NIGHT. When voltage
drops below approximately 20 volts, beacon light may become inoperative.
13. BEACON lights switch -- OFF , then as required.
8-17. ABORT START PROCEDURE.
CONDITION lever -- FUEL CUTOFF.
1.
ENG START switch -- STARTER ONLY.
2.
TGT -- Monitor for drop in temperature.
3.
ENG START switch -- OFF.
4.
8-18. ENGINE CLEARING PROCEDURE.
1. CONDITION lever -- FUEL CUTOFF.
