The handle to operate the rudder pedals fwd or aft can be stuck at the end of its stop. This frequently arouses the idea that there is something wrong. Often when the rudder pedal is at it’s extreme forward or aft position the design feature of the pedals is in such a way that it gets locked. If you apply a considerably force on the handle the mechanism comes loose. However, pay attention you turn it the correct way. So just rotate the adjustment lever with a little more force you may hear a little latch breaking sound then the pedal becomes free to move fore and aft.
Update from Tom: Rudder pedal adjustment jammed full travel fore or aft: Reference 400 amm 27-21-00/101 troubleshooting. (not in NG manuals!) These jackscrew units are all the same in the fleet, This t/s guide recommends backdriving the adjustment crank up to 100 in/lbs, it may actually take more, using adjustable wrench on flats opposite crank knob turn CW to drive pedals forward CCW to drive pedals aft. Light tapping on jackscrew at same time also helps.
