Both aircraft are fitted with Pen Yan conversions. This upgrades them to a Superhawk, by the fitting of a 180 hp engine and a fixed pitch Sensenich propeller. Consequently both benefit from an increase in performance, including a 250lb increase in maximum gross weight.
They each have long range tanks, GPS, four place intercom, nav comm, ADF, transponder, and sheepskin seat covers. Regular refurbishment of the interiors has kept the aircraft looking very tidy.
