Posted 9 December 2015 · Add Comment

Pratt & Whitney Canada (P&WC) can begin testing on its new PT6A-140AG turboprop engine, selected to power Air Tractor's new AT502XP aircraft.

P&WC received authorisation for field testing of the engines in Brazil this spray season with S10 and S500 Type B biodiesel comprised of up to 10 per cent bio content. The company also received approval for the S500 and S10 Type-A regular diesel fuel.
"The launch of the new PT6A-140AG and our advancements related to biofuels demonstrate our commitment to the agricultural segment and our ability to continuously innovate and raise the bar with the PT6A family to make the world's best engines even better," said Denis Parisien, vice president, General Aviation, P&WC.
The new engine aims at improved fuel efficiency, delivering 15% more power and 5% improved specific fuel consumption. It allows full-load takeoffs with maximum power in environments up to 111ºF (44ºC), making it appropriate for hot and high environments.
Field testing will begin immediately with full approval of the biodiesel expected at the start of 2017.
