Flap Intermittent Problem

[LostKiwi]

Thought I would add to this...

I had very similar issues with my flaps as the original post.
Replaced the flap control cable with a new unit from Don Nieser.

Pulled my old one out and lay it on the hangar floor, it felt smooth as silk.
However, as soon as I put the bends back in it, i felt it immediately bind up.
For the price of these things, its not worth messing with it to try and re-lube the cable and carry on. They do run through a weird series of bends to get from the front of the airplane to the back.

Its a fairly straightforward job, but does require the removal of about 90% of the interior - get ready to spend some time laying on your back under the instrument panel.

Only real gotcha is the rigging. Once you get the approximate distance of the rod ends sorted out, there is a slot in the flap-motor end of the cable that allows you to change the throw of the bellcrank. Takes a bit of trial and error to get the right amount of travel to allow the flaps to come full up.

Now she works like a charm, and retracts fully into the wing. I was actually shocked at how much... I rekon she'll be 5 knts faster!
