More than one case of the test not revealing a failure. An Astir CS which had been in a trailing crash. The underside of the wing about 1 metre from the root had an obvious impact over the spar region. The frequency test did not show any significant change. However when the damaged area was opened for repair it revealed significant damage to the spar cap and web.
