The Bell 429 IGW (Increased Gross Weight) is a high-performance light twin-engine helicopter designed for multi-mission capability, including executive transport, medical evacuation, and utility roles. Introduced as an upgraded variant of the original Bell 429, the IGW version builds on the aircraft's proven platform with enhanced payload and performance features.
Certified in 2009 and still in active production, the Bell 429 IGW benefits from a maximum gross weight increase to 7,500 pounds (compared to the original 7,000 pounds), allowing for greater range, endurance, and useful load flexibility. It retains the same modular airframe and four-blade rotor system, known for delivering low vibration levels and smooth ride quality.
The aircraft is powered by twin Pratt & Whitney Canada PW207D1 engines, each providing 719 shp, and supports a maximum cruise speed of 155 knots. With auxiliary fuel, the 429 IGW offers a maximum range of approximately 411 nautical miles. Its maximum takeoff weight is 7,500 pounds.
Inside, the Bell 429 IGW features a flat-floor cabin and clamshell rear doors, allowing for easy loading and configuration. In executive layouts, it typically seats up to 7 passengers, excluding crew. The total cabin volume measures approximately 134 cubic feet, offering ample space for VIP or mission-specific interior configurations.
Operators choose the Bell 429 IGW for its balance of speed, capacity, and modern avionics, particularly in demanding environments where both performance and safety are critical.
