Pratt & Whitney Canada is here with the recently certified PT6A-140, the latest version of a turboprop engine that will celebrate next year the 50th anniversary of its first delivery. The -140 is will power Cessna’s new Grand Caravan EX turboprop single, with 867 shp at takeoff. That represents a 28-percent increase over the -114A used in the Grand Caravan. Transport Canada certified the -140 last July. The FAA’s equivalent approval is expected “in the next few months,” according to Denis Parisien, P&WC vice president for general aviation.

CFM International has expanded its TruEngine program coverage to include content assurance guarantee (CAG) for subsequent buyers of qualified CFM56 engines. The engine maker launched the CAG in response to customer requests for more assurance of asset value upon the sale of a qualified CFM56.

UK-based Reaction Engines has carried out a series of tests on a key component for its new engine, the Sabre, which is capable of operating as both a jet and a rocket engine by employing a translating intake. The novel feature will enable the aircraft–such as the Skylon reusable spaceplane–that the Sabre will power to fly anywhere on earth in less than four hours or directly into space and back to deliver satellites or cargo.

Honeywell has shipped the first two new TFE731-40BR engines to Bombardier for the airframer’s new Learjet 70/75 program. The new engine adds 10 percent more takeoff thrust by replacing the -20AR or -20BR engines in the Learjet 40/45 with the -40BR. “We’re turning up the wick, and putting more power to it,” said Michael Bevans, Honeywell director of technical sales, Business and General Aviation.
