July 31, 2013 - South Carolina-based Air 1st and MT-Propeller Entwicklung GmbH received an FAA STC for the Mitsubishi MU-2B series of turboprops Wednesday at EAA AirVenture Oshkosh 2013.
Both companies announced the FAA approval after just eight months of extensive flight testing performed for low- and high-rpm versions of the fast and popular turboprop, powered by Garrett, now Honeywell, TPE331 engines.
With this certification the newest generation composite propeller is available to help give the MU-2B shorter takeoff numbers, improved climb rate, and faster cruise. The prop design simultaneously reduces the aircraft empty weight while reducing vibration and shrinking the noise footprint.
MT-Propeller, the leading manufacturer in composite propellers for 32 years, last week celebrated shipping the 50,000th blade manufactured for a Cirrus SR22.
MT props certificated for both Part 23 and Part 25 and are common on both private piston through turboprop regional airliners - including the BAe Jetstream 41 and Eurocopter's high-speed X3, which flies at a record-setting 255 knots.
The company's composite props have accumulated more than 110 million flight hours without an in-flight failure or airworthiness directives (ADs), one of the best propeller safety records in the aviation industry.
More than 120 STCs are available from MT-Propeller for various applications.
