Strange TQ Indications
« on: July 31, 2022, 11:34:17 pm »
Flew out to OSH last week and had an uneventful trip out. Today departing I was getting what best can be described as a “roll back” on my right engine TQ indicator on the Meggitt.

Indicated as low as 31% with no appreciable dropped in EGT (10 degrees) and no change in FF. I got no adverse ya. This happened several during the flight.

Any suggestions?

Side note and I don’t know if is related I had my first every hiccup on the right engine. For about 1-2 seconds I got a drop in TQ and Temp. Then right back to normal.

Sounds like a torque sensor to me.

I had EGT and all that drop off and act erratic on a night departure out of home airport. Got my attention, but didn't sense any adverse yaw. It was as simple as cleaning out the cannon-plug on engine firewall.
Slumming it in the turboprop world - so you don't have to.

Update, cleaned the TQ transducer electrical connection. 4 subsequent flights no issue.
