Single Plane/Single Pilot 135 with 2-pilot aircraft

[Ted]

No, I'm not thinking about starting a 135. I'm too smart for that now.

But while chatting with my wife about airplane stuff, I had the musing about "What about a single plane/single pilot 135, but if you want to use a 2-pilot aircraft?" My assumption is that you can't, that would drive you to a standard 135 certificate.

One of the people who knows the regs better than me I'm sure has the answer to this one.

My assumption is that you can't, that would drive you to a standard 135 certificate.

You would use 135 Single Pilot in Command which allows 1 PIC and 3 SICs. Beyond that would be a 135 Basic before you get to the standard level. However both have limitations like 9 pax.

I'm with Bell206. The single pilot/9 pax limit is a consideration. Another (improbable) route would be to have a part time on call co-pilot and you're limited to 19 pax. Likely be restricted to VFR single pilot.
Think back to the Kobe Bryant event. Aircraft was a Sikorsky S-76. The Flight Manual says that can be flown by a single pilot. The operator removed seats so that it was limited to 8 pax. Also removed the CVR and WX radar. Operated full time as single pilot.

My reading of Ted's question is that he is talking about an aircraft where 2 pilots are required by certification, not one where single pilot is an option as in the early Citations. In that case it would be no, even for Part 91.
