Hinges under stress - mechanical engineering type question

That sounds like a very good record. I guess there's no need to worry.

For the people that didn't visit the Zenith link, thats a sheet metal
hinge, no moving parts, just flexing sheet. I've seen this up close
and its pretty slick. One of those "Why didn't I think of that!" kind
of moments.


I'm concerned about corrosion on such a flexing member and how the
imperfections introduced could concentrate stresses during flexing and
cause
premature failure.



The system has been in use for over 20 years on hundreds of planes and
tens
of thousands of flight hours and, to my knowledge, none have ever failed.
The deflection angle of the ailerons is relatively small.
