Badiul Alam Posted May 21, 2020 Share Posted May 21, 2020 8Hey! Hercules world. I am facing problem with one of my prop of C-130B eng. While opening power lever, rpm goes upto 103% with Freq 410 Hz in Prop gov cont sw in Normal. Afterward rpm slowly back to 102% with Freq 402Hz. In Mach Gov RPM remain ok. We change the indicator guessing that if Frq is 402%, rpm should be 100.2%. No otgers flux. Any suggestion pl. Quote Link to comment Share on other sites More sharing options...
pjvr99 Posted May 22, 2020 Share Posted May 22, 2020 not sure why mech is ok, but it sounds like internal leak, maybe dome seals, pitchlock regulator seals, prop retaining nut seals. Quote Link to comment Share on other sites More sharing options...

As a 1st step we have changed the gauge. Let see what happened next. Thanks a lot. Quote Link to comment Share on other sites More sharing options...
