Diamond Aircraft Da40
Single Piston
The Diamond DA40 Star represents a significant evolution in general aviation training aircraft, distinguished by its Austro AE300 turbocharged diesel engine that runs on Jet-A fuel rather than avgas. Built by Diamond Aircraft Industries in Austria, the DA40 family entered service in 2000 and quickly became a favorite among flight schools worldwide for its modern composite construction, excellent visibility through its bubble canopy, and forgiving handling characteristics. The diesel variant, certificated in 2010, offers substantially lower fuel costs and improved range compared to gasoline-powered trainers, making it particularly attractive for high-utilization training environments. The aircraft's low-wing configuration, T-tail, and tricycle landing gear provide stable flight characteristics ideal for ab-initio training, while its Garmin G1000 glass cockpit prepares students for modern airline operations. With a maximum cruise speed around 147 knots and a service ceiling of 16,400 feet, the DA40 Star delivers respectable performance alongside exceptional fuel economy of roughly 5 gallons per hour. The type's composite airframe construction provides superior crashworthiness compared to traditional aluminum designs, and its 39-foot wingspan gives it excellent glide characteristics with a ratio exceeding 11:1. SkyMeter has tracked 91 flights across 11 airframes and 8 operators, with DELAWARE STATE UNIVERSITY AVIATION PROGRAM the largest observed operator.
Safety in context
The incident rate counts flights with ANY safety event detected by SkyMeter — go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
