Today I took 1st flight after my annual condition inspection to test for normal operations. I also did a SAVVY FLIGHT PROFILE to double check GAMI spread and ignition health.
BUT... for the first time ever (480 hours on engine) my prop control kept creeping up. My throttle quadrant has alway been super smooth and "easy" to move for all three controls (throttle, prop & mixture). But today, my RPM kept creeping up. In order to keep the RPM constant, I had to tighten the friction knob to the point that the mixture was SUPER tight, but RPM was "snug".
Not sure what could have changed??? Only thing I did was lube bearings, but I've this every year.
Anyone have any thoughts on what may have changed after 4 years. I really liked the fact that my controls were smooth and easy without creeping off settings during flight. Is there any way to adjust individual levers so one can be tightened (RPM) without affecting the others (mixture, throttle)?
