#3 TIT 30C higher at same fuel flow settings in C-130 Technical Posted May 20, 2011 Did this engine just suddenly get 30C hotter? Is there a baseline for this engine? EWngines wear and as they do they run hotter. Is this engine out of limits? If it is a sudden increase in temp the thermocouple system may be in question, but don't forget to look for bleed air leaks. Does this engine have a trim thermocouple? If so it may also have a trim resistor.
