Duncan Aviation has performed its first ADS-B upgrade on a Beechcraft King Air 350i, using the CMD Flight Solutions approved model list STC, at its satellite avionics shop in Cincinnati, Ohio. After doing some research on the turboprop twin, Bruce Miller, the shop’s manager, discovered that the CMD option would meet the specified requirements.

“CMD’s ADS-B OUT solutions cover almost every business jet, personal aircraft and regional jet flying today with the Rockwell Collins TDR-94/94D or the Honeywell Primus II radio suite,” said CMD vice president of sales and marketing Barbara Mahoney. She added that the company has approvals from several civil aviation authorities, including EASA, Mexico’s DGAC and Brazil’s ANAC, in addition to Transport Canada approval on the Learjet 60.

During the process, which took less than two weeks, the team upgraded the Rockwell Collins TDR-94D transponders and installed a single, centralized fail annunciator and a digital discrete adaptor for digital-to-analog output.

According to Miller, “The customer had to put down the aircraft for three weeks to remove the propellers for overhaul, and that gave us more than enough time to perform the installation.” He added that the customer was “especially pleased by how affordable this option is.”
