Thread: Pulls Left During Taxi

I have to keep right rudder during idled taxi to maintain straight ahead travel. I have checked air pressure on mains and LH and RH tires are equal. Where would I start to look for a cure? Unequal spring tension on rudder linkage? Or, could I have a "Non-centered" condition of the nose wheel with rudder pedals at "even" condition? I also am not sure that I am not bothered by unequal toe-in on mains but am scratching my head on how to come up with a fixture to check this out.

Why don't you contact some customer support?

This is "customer support".

this is unauthorized forum and this is customer support : http://www.flightdesign.com/index.ph...=customer-care

You missed my point. I am well aware that Flight Design has a website. There is a Flight Design distributor in my area where one can go to get expert repair. I prefer to rely on this forum to gain information on how my CTSW operates from other owners who have "been there, done that" and enjoy comminicating with these owners. I consider this forum a wealth of information based on experience.

OK. There are some things you should know:
If that problem was always that it could be one group of problems
If it appeared during exploitation than it could be the result of hard landing and some distortion.

So I strongly recommend you to contact your nearest authorized expert repair.

Hi Dick,

The steering control rod bellcranks just behind the top of the front suspension that go through the firewall need to be adjusted. If it pulls to the left then the right side bellcrank needs to be shortend by .5 -1.5 turns depending on how hard it pulls. You can lengthen the left side to accomplish the same result. Look at the control rods and see if one bellcrank has far more threads showing or not showing. That may be the one to adjust. If it pulls slowly over to the left then start with .5 turn, either lengthen the left side bellcrank or shorten the right side one. If it pulls fairly hard to the left then start with one full turn in those directions. What you are trying to do is bring the nose wheel track back slightly to the right so it tracks straight.

I would do it by adjusting .5 turn out on the left side and a .5 turn in on the right. Make sure these nuts are re-torqued to 80 in/lbs. When you loosen them hold onto the rod with something so you don't loosen the other nut on the other end of the rod inside the firewall. Make sure you put Loctite back on the allen head screws to the steering head.

Look in the maint. manual Nov. 2008, Rev. 6, page 4-70, para 4.3.3.4.6. This has a diagram and the nut to loosen is KA9996334 and the steering head screw is C9996218. Read the paragraph.
These are also fine adjustments for rudder cable tension. If you have any questions about this give me a call.


narasimha,
I am a Rotax authorized repair center and an FD service center.

Roger, you've provided great directions for checking out my concern. I'll have my friend Paul, who is a licensed RLSA-M, inspect the linkage.

For all who may read this thread, I rigidly follow all Flight Design directives in regards to the "Minimum Level of Certification" for ALL work that is done on my CTSW. I feel that we are very fortunate to be given the responsibility to manage our aircraft in the manner allowed under the Light Sport rules and would never jeopardize this by performing unauthorized repair or modification of my aircraft.

Thanks Roger. If we have questions, I'll give you a call.

Check also the 'vertical aligment' of the front gear . If the gear received a side load , the front gear leg might not be vertical.
That will put the nose wheel leaning one one side and will make the aircrfat turning
----just like a motorcycle ---

Jacques is right. The advise I put up is for a normal fine tuning and baring any damage on the front end from hard side loading, striking some thing or a nose wheel landing type problems.
