pjvr99 Posted March 27, 2017 Share Posted March 27, 2017 What is the LSGI TIT when stable after start? Also ff and Torque? If you shut down the engine and restart immediately, what are torque, TIT and FF? What are NGI torque, TIT and ff? What are ff, torque and TIT at 900°C? What are OAT and pr altitude during these actions? Can you run a direct reading Guage for CDP during these checks? I don't see fuel nozzles changed on your list; while you're doing that, put borescope in and check combustion cans. Quote Link to comment Share on other sites More sharing options...

Propflux28 Posted May 10, 2017 Share Posted May 10, 2017 I wonder what fixed the discrepancy? I wonder if speed valves are opening fast enough on low speed. adjust min flow on fuel control? Quote Link to comment Share on other sites More sharing options...
