Today, AEVEX Aerospace, a full-service provider of innovative aircraft and cutting-edge technological solutions to a broad range of government and commercial clients, announced an amendment to our current FAA STC that will now cover the DHC-6-400 Series Twin Otter series of aircraft as well as the DHC-6-300 Series Twin Otter series.

When outfitted with a Garmin G950 NXi/G1000 NXi avionics suite, this new product enables the DHC-6-400 series to operate in the Standard Commuter Category with an enhanced maximum take-off weight of 14,000lbs (6350 kg). According to Mr. John Zublin, VP of Advanced Solutions at AEVEX, “Our DHC-6-400HGTM STC will transform the DHC-6-400 series by combining a significant increase in payload capabilities with the most recent Garmin G950NXi/G1000NXi integrated avionics systems.” “The total package enables operators to increase revenue, optimise payload and range, and broaden the scope of their mission. By adding the most recent Garmin features into their GFCTM 700 three axis autopilot, we are working with Aerocorp Avionics to upgrade the capabilities of the DHC-6-400 series.” The company’s Director of Maintenance, Mr. Joshua Fox, continues, “The Garmin GFC 700 is an AHRS-based automatic flight control system that offers yaw damper, automatic and manual electric trim, and flight director capabilities for crisp autopilot control. For DHC-6-400 operators worldwide, the availability of a Garmin G950NXi/G1000NXi cockpit is a welcome option to enhance functionality and supports a smooth transition for pilots moving up from trainers into the regional airlines.”
The DHC-6-300HGTM STC enhances the original DHC-6-300 Twin Otter Series aircraft’s payload capability from 12,500 lbs. MTOW (5670 kg) to 14,000 lbs. (6350 kg). This represents an increase of 1500 lbs. (680 kg) or 12% overall and a 31% increase in payload based on an average empty weight of 7700 lbs. The PT6A-34 engines’ maximum 750 shaft horsepower as well as the four-blade Hartzell “Scimitar” propellers’ greater efficiency and noise reduction are permitted during operation. The changes are finished with additional structural and aerodynamic improvements. The DHC-6-300 and DHC-6-400 operators can run a revenue service without any special purpose limitations because they fall under the Standard Commuter Category STC.
