Plowing on with ~70 old Grob 103 Acros
Plenty of civilian clubs are ploughing on with old gliders with no problems. There are 31 G103s & Twin Astirs on the civilian register, four deregistered because they have gone abroad and one deregistered as it was destroyed in a mid-air collision. Thankfully all the pilots were OK in that incident.
It doesn't matter much how old or new the gliders are, if the paperwork etc. is allowed to get into the state that the gliders paperwork is in it's expensive to sort it out.
