Engine Operating Temperatures
If start ITT limit (Figure 3-4) is exceeded, abort start. Refer to
engine maintenance manual for corrective action.
If takeoff limit is exceeded, reduce power setting to bring ITT
within limits. Enter maximum temperature and duration in
excess of limit in engine log.
If takeoff transient limit is exceeded, reduce power setting to
bring ITT within limits. Make electronic computer N
1 adjustment
prior to next flight. Observe takeoff ITT limit. An ITT overshoot
resulting from application of takeoff power not exceeding take-
off transient limit is allowable and does not require an engine
log entry.
Maximum continuous limit is 832°C; however, for greatest
engine life under normal conditions, reduce engine power to an
ITT of 795°C or less after 30 minutes of maximum continuous
operation.
Engine Overspeed Limits
The maximum overspeed limits of the engines are as follows.
100% to 103% Turbine or Fan . . . . . . . . . . . . . . . .1 MINUTE
103% to 105% Turbine or Fan . . . . . . . . . . . . . .5 SECONDS
If 105% turbine or fan is exceeded, contact nearest Garrett
AiResearch Field Service Propulsion Engine Representative
prior to engine removal for overspeed inspection.
Engine SPR
Do not energize SPR switch at any time other than engine
start.
Information shown in italics is not included in the AFM Limitations chapter.
CAUTION: If a takeoff ITT of 870°C or more is attained for
more than 10 seconds or 930°C is attained or exceeded,
refer to the engine service manual for corrective action.
