I spoke to a friend and Duo owner today who visited
Southern Sailplanes (the UK agents and repairers) yesterday
where 3 Duos were examined using a small video camera
on a long pole. Apparently the inspections could be
done in 'about 10 minutes' per wing without inspection
holes being drilled in the wing skins.

He tells me that 2 Duos passed and one newish Duo failed.
