Pratt & Whitney Canada's (P&WC's) new PT6A-140AG turboprop engine has been selected to power Air Tractor's new AT502XP crop duster aircraft.
The new PT6A-140AG engine sets the benchmark for performance and fuel efficiency for the agricultural segment, delivering 15 per cent more power and five per cent better specific fuel consumption (SFC) than other engines in its class.
Optimized for extreme "hot and high" environments, the PT6A-140AG enables full-load takeoffs with maximum power available up to 111ºF (44ºC), effectively helping operators to increase their productivity and grow their profit margins.
The PT6A-140AG engine has 867 mechanical shaft horsepower (SHP) and 1,075 thermal SHP. Its modular design and externally mounted fuel nozzles make it the easiest engine in the agricultural segment to access and maintain.
The Time Between Overhaul (TBO) can also be extended up to 8,000 hours or 12 years depending on the operation and it is independent of engine cycles. Designed and built to outlast others in the same class, the PT6A-140AG has a minimum component life limit which is 50 per cent higher than competing engines, and will continue to be a productive asset for any operator long after similar engines have been sent in for overhaul.
Simple routine engine inspections can be done while still on-wing, in the field or in the hangar, eliminating surprises, reducing costs and providing peace of mind.
P&WC has also received Transport Canada authorization for field testing of PT6A-34AG engines in Brazil this spray season with S10 and S500 Type B biodiesel comprised of up to 10 per cent bio content. Additionally, P&WC was granted full approval for S500 and S10 Type-A regular diesel fuel.
Field testing will commence immediately and P&WC anticipates full approval of the biodiesel for the start of the 2016/17 season.
Based in Longueuil, Quebec (Canada), P&WC is a wholly owned subsidiary of United Technologies Corp. (UTC).
