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.
