Duncan Aviation earns multiple ADS-B STC approvals

Duncan Aviation’s Engineering & Certification Department has announced that it has received approvals from three civil aviation authorities for its supplemental type certificates (STCs)–ST01810WI  and ST01811WI–that upgrade the Honeywell Primus II system for Automatic Dependent Surveillance Broadcast-Out  (ADS-B) in Cessna 560/560XL and Hawker 800/800XP aircraft, respectively. Approved by the Federal Aviation Administration (FAA) in December 2015, the STCs have also been accepted by Transport Canada Civil Aviation (TCCA), Mexico’s Dirección General de Aeronáutica Civil (DGAC), and the 27-member nations of the European Aviation Safety Agency (EASA).

These approvals mean that aircraft in the countries that abide by those three civil aviation authorities can now access these two Duncan Aviation STCs and comply with the FAA’s Jan. 1, 2020, ADS-B mandate. Without upgrading to ADS-B by the mandate deadline, aircraft will face limitations or be denied the ability to fly in U.S. airspace.

“We’re proud to secure these authorizations because they let our customers from Mexico and Canada, and throughout Europe, know that we are committed to and respectful of their processes and procedures,” said Duncan Aviation’s engineering and certification business development manager Shawn Carraher. “It’s important to Duncan Aviation to be able to provide service to all of its customers, regardless of their global location, and these approvals provide more options for those needing ADS-B STCs around the world.”


Additionally, the Duncan Aviation Engineering & Certification Department has been developing STCs for various equipment and aircraft to give aircraft owner/operators as much choice regarding ADS-B equipment as possible. The company now holds or has access to 42 STCs for FAA-approved ADS-B equipment, which allows the company to perform upgrades on more than 100 aircraft models.

In the final 11 months before the FAA’s Jan. 1, 2020, deadline for its ADS-B mandate, roughly 45 per cent of the business jets in the United States have not complied. In addition to its Satellite Avionics Shops located at the busiest general aviation airports in the country, Duncan Aviation has three main facilities in Battle Creek, Mich; Lincoln, Neb; and Provo, Utah.
