My point was, a manufacture can weather a problem once,
simply because of its reputation. If it happens a second time the
customer will go with an other product.
In the case of the Diana it was critical to be proactive even if it
turns out that the manufacture was not at fault. The company has to
establish it self .

Maybe the analogy was not ideal as many pilots flew the 27 for years
and had the wings refinished if they were competitors. Many still
fly with the .005"plus shrinkage. I understand the gliders produced
after 2000 do not have that problem but this is just anecdotal.

Look for example the ASW 27 and it wing surface problem.

Udo, you are the second person that used the ASW-27 as an example in
this thread, but I'm not sure what it is intended to be an example of.

Schleicher had wing deformation problems with both the ASW-27 and to a
lesser extent with the ASW-28. I know of no corrective action
provided by Schleicher and I know for a fact that Schleicher claimed
the deformation on the ASW-28 was cosmetic only.

So my understanding is that Schleicher did nothing to correct the
problem and there were many very unhappy owners.

Do you know something different?

Schleicher also delivered several ASW-28 with incorrect airbrake
rigging. That problem was eventually resolved by changing the wheel
brake actuating rod to a part with different slot dimensions. In this
case Schleicher provided good support and also provided replacement
parts at no cost.
