The Sterling Air Services SAS 12 was the first fully functional and mass produced commericial propliner from the company, having this aircraft enter production in June of 1983. They have been known to produce many extraordinary aircraft electrical and navigational systems for other known brands like Boeing or Airbus, but this is their first full aircraft using their manufactured parts and technologies. This aircraft being the SAS-12-100 variant, is the first edition of the plane, being very adaptable to new or experienced pilots, as well as being very modular as much of the extra space on the plane can be used to accommodate newer technologies or parts as the years go by.
