Default DG-300/303 owners...

Are all DG300 certified "experimental" (in the U.S.) ?

Just finished reading this and the related thread. This is a nightmare for
the affected owners and many others in the industry!

However as a suggestion:

Would it be possible to determine if any one aircraft has the defect by
measuring wing deflection under a known load?

From my understanding of the defect, the misaligned fibres would not only
reduce the strength of the spar, but also it's stiffness. By measuring the
deflection of a sample of wings under load and then opening them up to
determine whether they have the defect or not, it might be possible to
draw up a non invasive procedure which can be used to determine if the
defect exists in a particular aircraft, and if it does, to what extent.

Anybody from DG reading this?
