On May 29, 2012, the new Bell 429 was introduced to the Belgian public scene at the heliport of Heliplus Spiere in Spiere Helkijn, near Kortrijk. 

The Bell 429 is a light-twin helicopter featuring a state-of-the-art fully integrated glass-cockpit based on single-pilot instrument flight rules and designed to be JAR-OPS 3 compliant including a Bell BasiX avionics package, a flight director, a dual digital three-axis autopilot and fully adjustable pedals and seating.

Developed by Bell Helicopters and Korea Aerospace Industries, based on the Bell 427. Although the 429 has the all-modular airframe concept and advanced rotorblade design from the MAPL (Modular Affordable Product Line) it maintains a derivative engine and rotor drive system from the 427. The first flight of the 429 prototype was on February 27, 2007 with type certification on July 01, 2009. It features a 4-blade rotorsystem with soft-in-plane flex beams and composite rotorblades with swept tips for reduced noise. The tail rotor is a two two-blade rotor set at uneven intervals (like an "X") also to reduce the noise signature of the helicopter.

Side or rear loading capability, large cabin windows, a spacious cabin with easely removable seating to convert quickly from passenger to cargo service, energy-attenuating passenger seats, collective mounted throttles, damage tolerant hub and rotor system… you can have it all and this at a cruising speed of 150 Kts. Twin Pratt & Whitney PW207D1 turboshaft engines with digital fuel controls provide a 'Category A' performance in all conditions.

Optional clamshell doors and rear-sliding/forward-hinged doors allow unobstructed acces from the rear or through either side.
During our visit the opportunity was given to have a flight in the 429 and the smoothness and quietness of the ride was striking. Ample of cabin space, easy access, a large luggage area,… a dream.
