Bump felt in control wheel

Postby ajs123 » 12 Apr 2017, 05:34

We had pilots complain about a slight bump in the Captain's control wheel at about 6 units left. We are unable to trace the source of the bump however. Strangely it goes away when the F/O control wheel is removed. Was able to move the bump to a different position of turn by adjusting the F/O backlash but it got too tight.

Yes always such a slight bump or binding feeling ?
Put some lube (wd40) on the fork assy. Hard to reach, but a handy tool (very large wd40 spray nozzle for example) you can reach it from the underside.

Well, the problem went away after lubing in the F/Os control column. I guess the bump was somehow translating across to the Pilot's side. I still don't get it because it was never felt in the F/O side.
