G102 spigot AD??? What's the status...

I heard an AD was being considered for the wing spigots on the Grob 102s
(US version AD). Any definite info on where this is headed and when?

Thanks,

Gary

Gary,

It is still stuck in the bureaucracy, I anticipate it being issued
when the FAA has the time to get to the low-priority items. I went
ahead and had the work done by XU aviation in Ontario.

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.

If you go to this page your question will be answered

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.

It is interesting to note that there have been no SDRs or incidents related
to problems with the spar spigots on G-102s in the US despite the fact that
the AD did not include the G-102 when it was issued for the G-103. This
would seem to indicate that whatever the issue was that prompted the SB to
be issued originally is likely not a problem in the G-102.

I was also surprised at the relative lack of response to the NPRM when it
was first issued last year. I would have thought that just about every
G-102 owner in the US would have responded suggesting that a more sensible
approach to the AD would be an annual inspection of the part with
replacement required if any defect was found, as opposed to the proposed AD
which will require outright replacement regardless of the condition of the
existing part. This is a major and expensive repair that is probably worse
than the problem it proposes to address considering how remote the
possibility of having a problem appears to be based on history.

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.

Is this alarming?
In 1971 the Design Authority issued an Airworthiness Directive mandating
the replacement of wing spigots on the Grob 102, following a failure on
the Grob 103. Aircraft manufacturers/Design Authorities do not issue
directives, which by their name are mandatory, for the fun of it, in fact
doing so indicates that have screwed up. The work mandated is essential.
Unless I have this completely wrong the FAA decided they knew better and
did not pass this on.
My concern is, how many other AD issued by Design Authorities have been
ignored by the FAA and is it really safe to fly in a glider, or any other
aircraft on the USA register? Can we be assured that essential safety
maintenance has been done?
Looking at the evidence of the Grob 102 the answer has to be no.
Have the FAA ignored other ADs issued by European manufacturers, Airbus
Industrie perhaps?
Scary!!!!!!!
