Your suggestion to report this to the Feds is worth serious consideration, particularly since the locking mechanism cannot be inspected without cutting into the frame. The "catch 22" is a bit rhetorical; what would prompt anyone from creating a window to inspect the thing unless there was already a problem? An A/D? For each Grob of this type, there are 4 bolts to check for each of the 2 canopies. Not much of a problem on the ground, but if you wanted to egress at altitude, the unlocked left side may prevent bailout even though the right-side emergency release worked.
Good thoughts, Thanks.
