Troubleshooting question: If you choose to help, greatly appreciated.


ONLY in cruise, one of our 139's RPM switch set at 100% at straight level flight momentarily bumps up 2% percent with no pilot assistance.

Collective wiring rang out good
LVDT's on order yet no test box

Any starting points?:ugh:
