An example is the profile warping of the ASW-27. Didn't really deter
anyone nor the reputation of Schleicher. Nor the spar delamination
problems of Schemp-Hirth sailplanes.

Or the incorrectly manufactured spars of the DG aircraft, resulting in
reduced operating ranges.

If these problems had occurred on the Diana-2 - people would have
screamed bloody murder. Instead, we had ONE customer who let an
unqalified person wreck their plane and then demanded the
manufacturere fix it all.

In the other cases involving the German manufacturers, it was a series
of discoveries on various aircraft that occurred due to manufacturing
problems, not due to a monkey mechanic wrecking the aircraft.

It's a shame for all involved.
