at any rate, although isn't all that common, at least in my region, it has been successfully done. it's best to have a close relationship with your local fsdo, as you can be sure they're going to be keeping a close eye on such operations for signs that it could be beginning to hold out to the public. you'll need an atco certificate for that. a decade ago, i helped a man assemble an ops manual, specs, etc. for a single-pilot part 135 atco certificate. his manual was approved and he was given a checkride after my ground/flight training by his assigned fsdo inspector. he operated a piper seneca. eventually, after about 4 years, he dropped the certificate and continued to only do work for 2-3 clients. you could no longer call him up for a charter flight.
