THE M-9-230 DIESEL
On July 18, 2003, Maule Air, Inc., manufacturer of the renowned Maule STOL aircraft, became the first US aircraft OEM to fly with the SMA SR305 Jet A powered diesel engine. Maule flew the M-9-230 to EAA Oshkosh AirVenture 2003.
This aircraft, which is based on the company's M-7 spring gear tailwheel
model, was very well received, as interest in this new
technology is very high. This particular model is a 5 seat, 4
door aircraft. The middle and rear seats are easily removable, turning this aircraft into a 2 seat cargo hauler. The gross weight on this new model will be increased to 2800 lbs. MTOW, up from 2500 lbs. MTOW. This economical Jet A burning engine will be fed from 4 fuel tanks totaling 85 gals. This is expected to give the aircraft a range of approximately 1000 miles. The turbo- charged SMA SR305 engine produces 230 hp for 5 minutes, then maintains 200 continuous horsepower up through 10,000 ft. MSL. Maule
is working hard to achieve certification.
