New turboprop sales continue their slow, steady climb out of the cellar. For the first six months of this year, the General Aviation Manufacturers Association (GAMA) reports sales of the segment are up 10.5 percent compared with the same period one year ago, with 243 delivered. Hawker Beechcraft King Airs, Pilatus PC-12s and Cessna Caravans lead the pack, as usual.
GE Aviation (Booth No. 3900) is planning on testing the first full Passport 20 engine, slated to power the Bombardier Global 7000 and 8000, in the second quarter of next year. The design of the 16,500-pound-thrust turbofan was frozen in April this year. A series of thorough safety trials is well under way.
Safran USA (Booth No. 2579) is flexing some considerable muscle here at the convention, showing a diverse role in the business aircraft market that stretches from nose to tail and wingtip to wingtip. Among the aviation products available from this global conglomerate are turbofan engines, nacelles, thrust reversers, landing gear, wheels and brakes, auxiliary power units, avionics, navigation systems, flight controls and wiring.
Covington Aircraft, a Pratt & Whitney Canada distributor and designated overhaul facility since 2009, recently expanded its approved capabilities to include maintenance, repair and overhaul on most PT6A engines. The company sells new P&WC PT6As and says it maintains an ample supply of rental engines to keep customers flying. Founded in 1972, Covington Aircraft still overhauls Pratt & Whitney R-985 and R-1340 radial piston engines at its Okmulgee, Okla. facility.
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.
