Narrative:

I am employed with an air charter company as PIC operating under far 135. The company manages an aircraft that can be operated under far 91 when utilized by the aircraft owner. I was assigned a series of flights with a pilot to fly as sic operated part 91 that was working for various company's part time as a sic on the same type of aircraft. On departure on this flight shortly after takeoff I made a turn too soon that is in violation of the SID that was caused by an error programmed in the FMS. The error was recognized by ATC; myself; and the sic at the same time. ATC gave us vectors. As PIC I am ultimately responsible however I believe that if our company operating procedures were utilized and understood better through training to the same level as required by far 135 standard operating procedures would better prevent this type of error.
