Mission Profile
About the Beech 18 (Turbo)
The Beechcraft Model 18, also known as the Twin Beech, was modified into a turboprop version called the Volpar Turbo 18. This conversion involved fitting the aircraft with Garrett AiResearch TPE-331 engines, which increased its maximum takeoff weight (MTOW) to 10,286 lb (4,666 kg). Additionally, some Volpar conversions included a fuselage extension and the installation of a tricycle landing gear system. The Volpar Turbo 18 is a unique and rare aircraft, with a sleeker, modern look due to the extended nose to accommodate the front nose gear. It was used extensively by Air America during the Vietnam War and was also employed by various freight operators in the 1980s. The H18 Super Twin Beech, a variant of the Beech 18, has a fuel capacity of 198 gallons
