When the G103 AD was done, what percentage were found

spigots been found cracked?
Is this a real problem or a CYA move?

The G103 spigot problem was due to faulty materials
in the manufacture of the spigot. Almost all of the
aircraft which used the faulty spec steel were found
to be cracked to some extent. The fix introduced replaceable
spigots so in the event of a future problem with the
spigots they can just be unscrewed and replaced.
The was a mandatory AD from Grob and the LBA in 1992
for the wing spigots to be replaced on G102 gliders
and certainly this mod was carried out in the UK. Looks
like you are just catching up with the rest of the
world.
