Regarding trim on jammed ailerons, IO540 said:
If the elevator is jammed whole so it can't move, the trim works the opposite way to normal
And this is true for the majority of aircraft. But the trim on, say, a Piper Cub works by moving the whole of the horizontal stabiliser, rather than moving a trim tab on the back of the elevator - and this type of trim, I believe, will work in the
correct sense. (Once upon a time I used to know the name of the various different types of trim, but my memory is fading.....)
It's worth understanding exactly how the controls on your particular aircraft work.
Anyway, congrats to Whirly for spotting the problem, although I'm not sure if congrats are maybe a little unnecessary since all she actually did was display the same good airmanship which is expected from all pilots.
Hope you identify the cause of the cause of the failure - and I'll be interested to hear what it is!
