Islip Avionics, Inc. was formed in October 1986 and received initial FAA Repair station Certification a few months later while operating out of a small office in the Mid Island maintenance hangar with a staff of three. Over the next few years the company increased capabilities and dealerships, and moved to its current facility then just built by Mid Island.

In December 1989, Fred Kattermann bought into IAI as President and General Manager. Fred, who started off with a background and degree in electrical engineering, is now also an A&P Mechanic, FAA Certified Repairman, and a Commercial Pilot with Multi & Instrument ratings.

In early 1994 Islip Avionics, Inc. purchased Precisionaire Instruments and leased an additional adjacent hangar bay, adding more capabilities to the growing station. Islip Avionics continued adding dealerships to stay current with evolving trends in the industry. When Garmin was formed, IAI was one of their first dealers (#20).
