Two new and more efficient versions of the venerable Pratt & Whitney Canada PT6A engine are coming to market.

The launch of the PT6A-140A and PT6A-140AG adds to 70 versions of the engine already in use on 125 different aircraft.

But the two latest models will deliver 15% more thrust and 5% better specific fuel consumption than any other version of the engine, P&WC says.

The announcement “raises the bar with the PT6A family”, says Denis Parisien, vice-president of general aviation for P&WC.

The PT6A-140 will be delivered with power ratings of 1,075shp (thermal) and 867shp (mechanical), allowing full-load take-offs at 44˚C (111˚F).

The PT6A-140A is aimed at general aviation uses, while the PT6A-140AG is reserved for agricultural missions, such as cropdusting.

Meanwhile, P&WC also has unveiled an exclusive service plan (ESP) for the PW800 turbofan engine.
