throttle come forward in flight to flight in C-130 Technical Posted November 14, 2010 I have seen this a few times. Different things have fixed it, from adjusting engine throttle cable tension to replacing springs inside the throttle quadrant. I would look at everything from the throttle all the way the to the propeller valve housing. Check the all cable tension, ensure your throttles are passing all pull checks, and inspect all bearings, turnbuckles, rod ends, and bushings. I have seen engine and propellers replaced and the issue continued. Don't be quick to call first thing you find wrong as the fix, take the time to inspect the whole system.
