AD 91-5/2, SB 306-29 issued in 8/91. This should have been completed 17
years ago, I can't believe the FAA is that slow.

Does anyone know where a copy of the service bulletin from grob might
be
found online? I googled this quite a bit, but so far no luck coming
up
with the actual document. Even the Grob website doesn't list the
SB...

Right, there is a master list, but on the left side SB 306-29 is NOT
shown unfortunately.


Unless I'm missing something - the link at the top does NOT appear to
provide any details of what exactly is involved with the AD. I'm
looking for the Service Bulletin which describes (hopefully with some
pictures or sketches) the repair.

You aren't missing anything. The SB does not really describe the
repair. Your mechanic has to get the parts and instructions from Grob
in Germany. Bob K. did describe the process though, which is the same
as for a G 103.

Forgive me if I am wrong but are you saying that Grob issued as a mandatory
replacement 17 years ago was not embodied in the USA? If that is the case I
am amazed. I am not surprised that the SB is not readily available, one
assumes that Grob, having issued a mandatory SD would expect that it was
completed long ago.

You are correct in saying that the mod was brought about by the failure of
a spigot on a Grob 103 wing, this was on the rig a Slingsbys during testing
for the RAF. Several other wing spigots on aircraft in service were found
to be cracked. The reason for the cracking was the wrong spec steel used
to manuafacture the spigots and this only applied to the 100 Grob 103s
built for the RAF and a few others which had been privately sold. Only
gliders showing cracks were grounded, others were subject to regular
inspection until Grob issued the mandatory mod requiring new replaceable
spigots. You are also right, it is a major job and may only be carried out
by organisations approved by Grob. If the FAA follow that line you will
need this:

Grob Aerospace Inc. has appointed Composite Aircraft Repair of Moriarty,
New Mexico as the new authorized service center for the 300+ Grob
Aerospace light aircraft and gliders in the United States.
