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.
GE has so far found no further evidence of improper installation of low-pressure turbine stage-one nozzles in GEnx engines following its issuance last week of a service bulletin that called for a fleet-wide borescope inspection.
GE has finished the first round of checks on all in-service and spare GEnx turbofans ahead of the September 21 publication of a U.S. Federal Aviation Administration airworthiness directive (AD) that calls for ultrasonic inspection of early-build engines’ fan midshafts every 90 days. GE has developed a field ultrasonic method to inspect the suspect area of the engines while they remain on the airplanes.

Rolls-Royce has completed testing of the latest build of a research two-shaft engine core, known as “Core 3/2d,” as part of the E3E (efficiency, environment, economy) program. The core evaluation campaign ends without a previously planned endurance test, however. E3E technology forms the basis of Rolls-Royce’s Advance2 future two-shaft engine program, which targets entry into service in 2018.
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. With this guarantee, customers who purchase a qualified CFM56 are entitled to a 50-percent credit on replacement parts if, at the first shop visit after transfer of ownership, any parts or repairs found in the engine are not original CFM parts or CFM-authorized repairs.
The European Aviation Safety Agency (EASA) issued an emergency airworthiness directive (AD) for the Rolls-Royce Trent 1000 engine on July 25, several days after All Nippon Airways was forced to ground five of its Boeing 787 Dreamliners when the engine maker flagged up problems during product development testing. The Trent 1000 powers all of the
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.
StandardAero Business Aviation has announced its Fastlane program for operators of Honeywell TFE731-powered aircraft. Under the program, business jet operators can have guaranteed completion of a core-zone inspection in 14 days or less. Industry averages currently range from 30 to 40 days, according to StandardAero (Stand 671).
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.
