Not me, but...
Some years ago I was in the back of a Wessex, just about to coast out, when I noticed a ploughed field approaching alarmingly quickly. We made a loverly 3 line groove in the soil. The pilot mentioned a 'floppy cyclic', but not enough time to say 'Mayday', or 'Brace', or something else suitable. Banter aside, he did a good job to cream us on a sloping ground.
Memories fail, (early 80's) but I think it was connected to the Stab, and the yaw, pitch and roll thingies in a cupboard. The Auto Stabilisation Equipment (?) (ASE) pack springs to mind as the source of all things evil to aircrew.
Not much detail, I'm afraid, but that was generally the source of flying control faff's.
