Key Takeaways:

Valdor Aircraft received Supplemental Type Certificate (STC) approval to extensively upgrade de Havilland DHC-2 Beavers.
The "BX Turbo Beaver" modification replaces the original radial engine with a modern Pratt & Whitney Canada PT-6A-34 turbine, coupled with new wings, fuel/electrical systems, and carbon-fiber cowlings.
This comprehensive modernization aims to boost performance and efficiency, meet current aviation regulations, and ensure the continued service life of the aging Beaver fleet which often has outlived its original engines.

Valdor Aircraft, a Quebec company that provides a range of aircraft services, received supplemental type certificate (STC) approval to install Pratt & Whitney Canada PT-6A-34 engines in de Havilland DHC-2 Beavers.

The recently approved upgrade goes beyond replacing the Beaver’s original Pratt & Whitney R985 radial engine with a modern turbine to increase performance and efficiency. The re-engined Beavers receive new wings, fuel, oil, and electrical systems, engine monitoring, carbon-fiber cowlings, and more. Valdor calls the almost-all-new aircraft the BX Turbo Beaver.
