Recently Maule has renewed their website.
On their old web site they had
a news link about the certification of the Maule M9.
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.
On
their new website this information has been removed and there is no information about future development of diesel engines in Maule aircraft.
Q: Has Maule discontinued the certification process of the diesel engine?
Recently the
SMA SR305 engine received EASA certification
