True, but we don't have 50 years of experience with composites in

understand fatigue and corrosion issues in aluminum...

My outrage is not whether the composites have a problem, but the method with
which they are to determine if there is a problem.

With some question (there must be a concern, hence an AD) there HAS to be a
better way than a tap test. It does nothing for my confidence.

Sometimes the simple tests really are the best. Visual inspection by
human eyes is still used for a lot of things even though it is well
known to have lots of problems (variability among humans being one of
the biggest).
