The FAA has granted Pro Star Aviation approval for an amendment to a supplemental type certificate (STC) that allows it to install a universal antenna mount (UAM) and lower fuselage radome on several Textron Aviation aircraft, including the Beechcraft King Air 350 and 350C.

Through the amendment, operational configurations were expanded to allow up to four antennas on the UAM without a radome. Also, visual inspection intervals on the UAM were increased to 800 hours (Phase 4 inspection). An optional design for aircraft pressure feed-through panels was added, meaning that the panels could be removed from the aircraft interior without removing the UAM and radome. Last, the amendment incorporates deviations found in follow-on installations in radome mounting points caused by variations in aircraft production.

New Hampshire-based Pro Star Aviation offers services such as maintenance, modifications, STC development and installations. With its main facility at the Manchester-Boston Regional Airport, the company offers on-site and on-location support throughout the Northeast U.S.
