Pratt & Whitney Canada's PT6A-140AG engine in service on AT-502XP



Marking a successful entry into service (EIS), roughly 25 PT6A-140AG-powered AT-502XP aircraft have been delivered to customers around the world since certification, the company said.

The EIS of Pratt & Whitney Canada´s latest engine for aerial application aircraft is progressing and as the application season in the Northern Hemisphere winds down, the engine has been performing very well. Pratt & Whitney Canada (P&WC) is a subsidiary of United Technologies Corp. (NYSE:UTX).

Located in Iowa, Louisiana, O´Brien Flying Service bought two AT-502XP aircraft for the 2017 spraying season. The two aircraft flew about 1,400 hours during the season.

Optimized for “hot and high” environments, the PT6A-140AG engine provides its full 867 shp capability up to temperatures of 111º F (44º C), effectively helping operators increase their productivity by maintaining full loads all day long. With higher cycle limits on all rotating components than competing engines, the PT6A-140AG will continue to be a productive asset for any operator after other engines have been sent for overhaul.

Air Tractor´s AT-502XP has been validated by aviation authorities for use in the United States, Canada, Brazil, Argentina, South Africa and Australia – all jurisdictions where the aircraft is now flying.

The PT6A-140 engine was originally certified in 2012 to power the Cessna Grand Caravan EX. Subsequent to the introduction of the PT6A-140AG engine variant created specifically for the aerial application segment, both aircraft manufacturers in the agricultural industry, Air Tractor and Thrush, have selected the engine for their 500-gallon aircraft.
