Duncan Aviation is installing Archangel attitude and heading reference system (AHRS) upgrades for Pilatus PC-12s equipped with obsolete Litef LCR-92/92 AHRS. The MRO supported Archangel’s certification of the upgrade, which replaces units that Duncan said have limited support, rising repair costs, and costly upgrade paths.

The recently FAA-approved replacement AHR150A AHRS is available for installation at Duncan Aviation MRO and satellite facilities and at customer locations. The company can install the AHRS in less than a week, thanks to the Archangel adapter plates designed to fit the existing LCR-92/93 mounting locations. Archangel also developed adapter wiring harnesses that connect to the existing aircraft wiring.
