I was thinking that Richard Kaplan did that in his P210, but I haven't
seen any posts on usenet from him in quite a while....yes, here it is (or
google for "kaplan 135")...

Yes, I did it and it is still permissible.


See FAR 135.163 redundant alternator/gyro requirements. There is also
an FAR requiring a 3-axis autopilot if the operations will be single-pilot
and requiring an approved engine trend-monitoring program for single-engine
aircraft. I did all this and had single-pilot, single-engine piston, IFR
night/day known-icing approval.
