hello sir thanks a lot for your courses i want to know if you have a task card for light overhaul because we have an issue with our PT6A-42 which remained a long time whithout functioning any help and advice will be welcomed
PT6A engines with the Bendix FCU can have runaway if the plastic coupling between the FCU and HP fuel pump is not installed. Those with Woodward FCUs like the PT6A-60A will accelerate to and hold at about 85% N1 should the FCU's N1 feedback fail; very rare as the coupling on this is metallic.
