The Banyan maintenance team has partnered with Texas Turbine Conversions from Celina, Texas to perform an exciting engine upgrade utilizing an STC (supplemental type certificate) developed by Texas Turbine Conversions called the “SUPERVAN 900”. The existing Pratt and Whitney PT-6A engine was removed and a factory-fresh Honeywell TPE-331-12JR is being installed. This complex engine upgrade includes replacement of not only the engine, propeller, and all associated wiring and batteries, but also includes a complete redesign of the cowlings and exhaust system.
This engine conversion will provide the operator with increased horsepower going from 675 shaft-horsepower with the original engine to a whopping 900 shaft-horsepower. Additional benefits include reduced fuel burn and longer maintenance intervals, which results in lower overall operating cost.
While performing the extensive engine modification, the Banyan avionics team is also upgrading the avionics suite. The existing Garmin stack and electromechanical instruments will be replaced with a dual Garmin G600 panel, dual Garmin GTN 750s, GDL-69A unit, and L3’s trilogy ESI-2000 for a complete glass makeover.
