Hi Frogspawn,
well I will give this man a try!
By now we had a tech from Turbomeca-Mexico here. We had all electric and electronic connections checked and cleaned - An anoying FLI failure went away, seems a dirty Torque sensor connection was the culprit.
Also found one badly worn thermocouple - promptly changed the whole harness:
GUESS WHAT: First 2 start-ups everything fine and perfect, ALL RIGHT!!
Started up today, BACK TO THE SILLY GAME!!
So I will write up that stuff and send it to the man you recommended!
Any more ideas out there?
