I am involved in a lawsuit right now where that was the exact relationship. The aircraft was owned by an LLC. The LLC dry leased it to the 135 certificate holder. Then the pilot owner of the LLC was the pilot that flew the aircraft. The FAA mandates that if you do lease the aircraft to a 135, it must be a DRY LEASE, which means among other things, that it not include the pilot, and that the 135 operator at all times has the right to select the pilot. Otherwise, the owner must have a 135 certificate itself. Expect that you will have to pay a substantial conformity inspection fee to put the aircraft under their 135 certificate, management fees, costs for the pilot (and if required, a co-pilot), and to pay all expenses. In short, don't expect to make much, if any money doing so.
