Before I purchased any glider manufactured by either of these subcontractors I would insist on a full-blown ultrasonic NDT test.

This relevant accident happened in 2003.

Before I get my nickers in a twist, I'd like to know whether the manufacturing deficiencies have been addressed in the intervening 16 years.

SH issued an AD on affected ships. Presumably all were inspected and repaired as needed a long time ago.
I recall that SH did take action to document the process areas that had been done only by hands on training. I don't have written info on this.
SH stepped up on this and did what I consider a good job when the issue was identified. I had an affected glider at the time and the inspection was prompt, thorough, and cost free.
