Premier Aircraft of East Alton, Ill., has entered an agreement with Honeywell Aerospace to upgrade the existing TFE731-3-1C and TFE731-3D-1C engines installed on Falcon 50s to a TFE731-4-1C configuration. Premier will market, develop, engineer and certify the “50Dash4” upgrade, which includes engine installation, related hardware and cockpit instrumentation.
According to the company, the three-engine upgrade will provide several performance enhancements and operating-cost benefits, including greater range, better time to climb, increased hot-and-high performance, higher cruise thrust and longer maintenance intervals. The upgrade will include a three-year/1,800-hour warranty on the engines and will lower the current MSP rate. It also includes the installation of N1 DEECs as well as the latest technological advancements from the OEM. The STC approval date, and the first customer input slots, is set for the fourth quarter of next year.
