Why oh why
The slow rate of initial progress I am told was due to the type certificate holder being slow to answer technical questions and supply repair data.
The supply of parts has been erratic and some involved with this process have no understanding whatsoever of Glider maintenance.
From a purely mechanical point of view the first glider has been ready to fly months ago, but paperwork issued both of history and the process going forward delayed things.
I do find it rather rich that anyone can defend a system that has so consistently over a considerably time scale failed to come up with the goods.
