If one FSDO accepts this addendum...would others have
too? One of the frustrations of the current process
for us...is differnet interpretations of the memo from
different offices.

Is anyone aware of someone who has tried this route
yet?


The whole reason to do an stc is to gain the
stamp of approval that is recognised by all fsdo's.
An stc is accepted across fsdo boundarys.
A 337 attempt on the other hand is a local
approval and has no national standards for
acceptability. The local area sets it's own rules up and
thats that. The differences between a moderately complex
337 and an stc is timing. The mido guys have a backlog and
schedule to work with while the fsdo office is a bit more
flexible .
