The CAA and the insurer will ignore the 50,000 previous times you landed in a 50 knot crosswind if you break the aircraft while landing in a 20 knot crosswind when the max demonstrated is 15.
I cant imagine they would - it could go horribly wrong.
So you are telling the Court that you meant to use the word "limit" but actually wrote "maximium demonstrated".
Hmmm, could end up with a product liability suite me thinks.
I would rather be defending.
