3. An STEC A/P which runs on the TC, rather than the vacuum
instruments, is the way to go.

I agree, the STEC even has a separate altimeter (actually a
differential pressure transducer) with its on dual air inlet
placed midsection.

One question: was the A/P engaged during the AI fail ? Do you
think that would have made a big difference in keeping the
aircraft under control ?

If it wasn't engaged, did you engage it immediately ? Did you
wait to get the aircraft under control with the T&B before
engaging it ?

Thank you, and congatulations on your sucessful handling of
the situation.
