Transport Canada approved operation of the Bell 429 at an internal gross weight of 7,500 lb (3,402 kg) in December 2011, increasing the platform's gross weight and enabling customers to operate with greater payloads. To date, the Bell 429 increased gross weight (IGW) has been approved by more than 25 countries, including Canada, China, Brazil and Australia with pending validation in additional nations.
Operation at an internal gross weight of 7,500 lb (3,402 kg) requires installation of the following equipment:

Additional IGW equipment adds approximately 21lb / 10kg of weight to the base aircraft empty weight
