Power
Essential to the performance of any aircraft is its power plant. The BT-67 is superbly equipped in this respect with the PT6A-67R Turboprop engines from Pratt & Whitney Canada and 5-blade metal propellers from Hartzell.
The PT6 engine type has been the engine of choice for commuter airlines for over 20 years. It has established itself in terms of the highest reliability and durability in conjunction with the lowest operating cost. It powers over 12,000 aircraft (100 types) in 160 countries around the world and has accumulated over 162 million hours of service.
