Diamond Aircraft Da40

Single Piston

The Diamond DA40 Diamond Star is an Austrian-built four-seat single-engine aircraft that has become one of the most popular training and personal touring platforms since its introduction in 1997. Built almost entirely from composite materials, the DA40 features a distinctive T-tail, low wing, and bubble canopy that provides exceptional 360-degree visibility — a design choice that has made it a favorite among flight schools and private owners who value both safety and the pure joy of flying. Its glider heritage is evident in the sleek aerodynamics and benign handling characteristics that make it forgiving for student pilots while remaining engaging for experienced aviators. Powered by either a Lycoming IO-360 or the fuel-injected Austro Engine AE300 turbodiesel (in the DA40 XLS variant), the aircraft cruises comfortably at around 140 knots with a range exceeding 700 nautical miles. The composite airframe is not only lighter and more fuel-efficient than traditional aluminum construction but also remarkably durable and corrosion-resistant, contributing to the type's reputation for low maintenance costs and long service life. The DA40's safety record stands out in general aviation: its one-piece composite safety cell and crashworthy design have earned it one of the lowest fatal accident rates in its class. The type has found widespread adoption in both Europe and North America, serving flight training organizations, air taxi operators, and private owners who appreciate its blend of efficiency, comfort, and modern avionics integration. The spacious cabin accommodates four adults with reasonable baggage capacity, while the large canopy and excellent forward visibility make it ideal for both cross-country touring and pattern work. SkyMeter has tracked 8 flights across 2 airframes and 2 operators, with TRUMBLY ROBERT ALLEN, HORTON PAMELA ANNETTE 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.
