T206H HEAVY RIGHT RUDDER

Guys,

New purchase of my T206H which is a phenomenal plane. From my research, the T206H does requires quite a bit of right rudder. My plane needs very heavy right rudder on takeoffs, landings and cruising (on auto pilot) . Are there any items that I should check. The the plane has vortex generators. When cruising and on auto pilot, the rudder trim is all the way over. Thank you for any input that you can provide. 310 hp Lycoming with a new McCauley standard 3 blade. Paul

    Hi Paul,
    I will send your question to our association A&P once I get your answer to this question. I'm delaying sending this to him first because I know he will ask the same question.

    Have you had the plane rigged? Get that done professionally and if the problem is still there I'll get our A&P involved.

  • Scott, thank you for the reply....Yes all flight control cable tensions and travel limits as per Cessna 206H Service manual completed on December 28th, 2020 during the annual.

    OK, I'll get your question over to our A&P Erich Rempert. Stand by.

    Here's a response from Erich Rempert:

    Cable tensions and travel limits are important but often adjusting the tensions is the cause of rigging problems not the fix.

    You need to have someone familiar with rigging look at the airplane and see if something is amiss.

    In cruise you say the trim is almost full right; once adjusted is the ball centered?

    Ill assume it is, and i suggest you get the trim set in cruise (ball centered) and then leave the trim in that position and try some other flight regimes and see how much rudder is required with the trim left in the cruise setting. If you find no rudder is needed at low power and the rudder is manageable on take off etc, I'd suggest that the trim indicator/control knob is where the rigging problem is.

    It's very unlikely the airplane is so far out of whack to need full right rudder trim on landing, it seems to me "neutral" is offset to the right for some reason.

    Have a rigging specialist look at the airplane and fly with you if necessary. In smooth air holding wings level and centering the ball should not require much trim. With the ball centered, the airplane should not have a heavy wing.

    Flap position should not have a noticeable effect on the above either. Lastly, does this seem like a slow example of the 206 or is it about what you'd expect? If the rigging is off or fighting itself it tends to slow the airplane down.

  • Scott, great analysis by Erich, thank you to you and Erich. I will take the above recommendations as suggested.
    Erich is correct to assume, the above was always in coordinated flight (ball centered). I will report back with the findings to facilitate any future question regarding to this issue. Thanks again.....outstanding forum Scott. Paul

  • Interesting! I have the same issue but requiring left rudder trim on my T182T. It does not require full trim but is 1/3 left by the indicator. I trimmed it up with ball centered and level flight, no wing drop with just me in the plane. I have flown it this way for some time.

    I too have the vortex generators. I remember making an trim adjustment after they were installed. I am wondering, if they were offset just tiny bit, would that cause the same issue?

  • Larry....very interesting twist......that never crossed my mind prior to your post.... I will check into. I have scheduled to have my plane inspected as per Scott & Erich.

  • Scott, Erich & Larry,
    UPDATE ON RIGHT RUDDER:
    I will be getting my plane back from the the shop this coming week, after a list of software updates to the avionics, as well as a couple items that needed to be addressed. The rudder had skipped over the pointers #1, #2 the controls and rigging were adjusted as well, #3 one of the wheel pants was canted and not straight. All three issues I am sure contributed to the heavy right rudder. The Ap's will be flight testing on Monday. I will keep you posted. Larry, I will inquire on the correct procedure to check the proper alignment of the VG's. Unless someone knows from the forum.... Erich! Great feedback from all of you, thanks again. Paul

  • Special accolades to Scott Sherer & Erich, on their spot on assessment regarding the heavy right rudder! Cessna Owners, we all have an outstanding resource right here with Scott Sherer & Erich, they both have tremendous knowledge to help us stay safe and learn at the same time! Thank you guys. Best, Paul
