Description
This Turbo Commander has everything you could want. A Grand Renaissance airframe with the Supreme Commander mod, winglets installed, and the wing spar lower cap replacement (CK144 kit) complete. Upgraded Honeywell TPE331-10T engines that carry matched times, and Hartzell three-blade props fresh out of overhaul in February 2026.
The panel stands up to anything in class: dual Garmin G600 TXi EFIS, GTN-750 and GTN-650 navigators, GTX-345R with ADS-B In/Out, GWX-75 color radar, GDL-69A datalink weather and SiriusXM, GI-275 standby, and Flight Stream 510. Pair that with the S-TEC 3100 autopilot with preselect and Keith Freon air conditioning, and this airplane is ready to go to work.
The plane is cosmetically excellent. Matterhorn white paint laid over a full strip and prime in 2020, and an executive seven passenger interior refurbished in 2021 in Moore and Giles leather, sheepskin, and wool carpet.
Consistently maintained by the top Commander providers. Complete logs throughout. Located in Conroe, TX (KCXO). Contact High Performance Aviation for full specifications or to arrange a viewing.
