Global Aviation Technologies will update 19 C-21A jets, which are military versions of the Learjet 35A, for the U.S. Air Force. The contract is valued at $32.2 million.

The company received the first of the 19 jets, which will receive new avionics, automatic dependent surveillance-broadcast, or ADS-B; Future Air Navigation Systems, or FANS 1/A; and electronic flight information systems.

The aircraft, produced in Wichita, were delivered to the Air Force from April 1984 to October 1985 to carry passengers and cargo for aeromedical evacuation.

Woody Cottner, GAT’s vice president of business development said, “We are proud to contribute to the further utilization of these Wichita-built airplanes. We’ll be updating the avionics to take full advantage of the advances in electronic flight management. We’re also very familiar with the Learjet airframe and its performance and durability, so this effort is both economical and practical on the part of the Air Force.”

The company plans to hire additional technicians before year-end to accommodate the work.
