Diamond Aircraft's ambitious plan for lightweight business jet faces indefinite delay

In December 2016, Wanfeng Aviation acquired a majority share of Diamond Aircraft Canada. This acquisition led to further suspension and reassessment of the D-JET program. Although there were suggestions that the program might resume, it remains shelved.

Diamond Aircraft Industries has roots tracing back to the early 1980s. The D-JET's design included features such as low drag characteristics and enhanced passenger comfort with reduced noise and vibration levels. It also offered ample storage space with externally accessible baggage compartments.

The aircraft could achieve high stability during flight maneuvers due to its engine placement near the center of gravity. It was powered by a Williams FJ33 turbofan engine generating up to 1,900 lbf (8.5 kN) thrust.

According to Diamond Aircraft: “The D-JET is designed specifically for the owner pilot... makes the D-JET the ideal Personal Light Jet.”

Key specifications included a maximum speed of 583 km/h (362 mph), cruise speed of 444 km/h (276 mph), range of 2,500 km (1,600 mi), service ceiling of 7,600 m (24,900 ft), and rate of climb at 8.467 m/s (1,666.7 ft/min).

The Full Authority Digital Engine Control system provided precise electronic controls for safety and efficiency. The system's dual-channel philosophy ensured redundancy for critical components.

Overall design considerations contributed to stable takeoff roles and efficient flight operations through features like large slotted wing flaps and a Garmin G1000 glass cockpit enhancing situational awareness.
