F.A.A. Approved November 17, 2015
After advancing the fuel control cutoff, a delay of lightoff can occur under
certain conditions. If this delay exceeds 3 seconds, return the fuel cutoff
control to the CUTOFF (OUT) position to abort the start, but motor the
engine for 10 seconds to clear the combustion chamber of residual fuel.
For subsequent starting attempts, repeat the complete starting sequence.
Monitor the TOT throughout the start. The TOT limits during the start are
as follows:
TEMPERATURE RANGE TIME
Up to 810C No Limit
810 – 927C 10 Seconds
927C 1 Second
Over 927C Not Allowed
NOTE
Refer to the Rolls-Royce 250-C20 Series, Operation
and Maintenance Manual when start temperature
consistently exceeds 860C.
NOTE
It is the responsibility of the pilot and maintenance
personnel to record the extent of and to take the
recommended corrective actions after an
overtemperature occurs.
CAUTION
IF THE PROPELLER IS NOT ROTATING BY 25%
N
1
SPEED, ABORT THE START. A SECOND OR
THIRD START ATTEMPT MAY BE MADE IF THE
PROPELLER CAN BE ROTATED BY HAND.
If a stagnated start is experienced, or if it appears that the TOT will exceed
the starting limits, abort the start by putting the fuel cutoff control to the
CUTOFF (OUT) position and motor the engine for ten seconds to clear the
combustion chamber of residual fuel. For subsequent starting attempts,
repeat the complete starting sequence. A normal start should be
completed 25 to 60 seconds after starter engagement; however, if N
1
and
N
p
are accelerating and the TOT is within limits, the start may be continued
longer than one minute.
If several starter cycles are necessary, the following starter/generator
cooling periods are to be observed:
1

cycle: 30 seconds ON – 1 minute OFF
2
