Butler National subsidiary Avcon Industries is offering two special-mission modifications for Bombardier Challenger 604, 605, and 650 twinjets under new supplemental type certificates (STCs) issued by the FAA. The modifications are for fuselage underside rail mounting provisions for sensors and mission equipment and a fuselage underside-mounted radome.

The Challenger rail system STC is similar to a previously approved Avcon STC for Beechcraft King Airs and Cessna Caravans. The rails can accommodate mission sensors such as large radar systems and electro-optical/infrared equipment.
