Delays associated with the Pratt & Whitney PW1217G-powered Mitsubishi Regional Jet (MRJ) haven’t deterred the U.S. engine maker from proceeding with its test program as planned.
The FAA has issued an airworthiness directive for all Honeywell ALF502L-2C; ALF502R-3; ALF502R-3A; ALF502R-5; LF507-1F; and LF507-1H turbofans. The AD was prompted by two reports of engines experiencing uncontained release of low-pressure (LP) turbine blades. The AD requires operational checks of the engine overspeed trip system to prevent LP turbine overspeed, which could lead to uncontained release of the LP turbine blades and damage to the airplane.
Pratt & Whitney Canada expects to assemble and ground test the first PW800 demonstrator “some time this year,” P&WC president John Saabas told AIN during Pratt & Whitney’s “Media Day” event, held last month in Hartford, Conn. The PW800, which had won a place on the now defunct Cessna Citation Columbus in 2008, lost its only application when the program was suspended in 2009.
A looming pilot shortage, stubbornly high fuel prices, industry consolidation and new regulations that will require, among other items, first officers to carry an Air Transport Pilots certificate by August 2013 all made their mark on the 37th annual Regional Airline Association convention, held May 21 to 24 in Minneapolis.
Snecma has finally found an aircraft for its Silvercrest engine to power after Cessna announced its selection here yesterday for its Longitude super-midsize jet, which is scheduled to enter service in 2017. It has been almost five years since the French manufacturer announced that it was to develop its first business-jet engine program, but finding its first application has proved to be a frustratingly long road.
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.
Pratt & Whitney Canada claims to have improved turnaround times for customers by 20 percent through a number of advances and innovations. For example, its online diagnostic tool enables customers using its PW300 turbofan, PW100 turboprop and PW200 turboshaft engine families to diagnose their engine issues quickly.
Here at the EBACE show, the engine maker is introducing a new product called flight acquisition storage transmission (FAST). This automatically acquires, stores and transmits engine and aircraft flight data for analysis for planned maintenance.
Development is well under way for GE Aviation’s 16,500-pound-thrust GE Passport 20 engine, which is set to power the Bombardier Global 7000 and 8000 business jets. The first engine is to begin ground testing in the second quarter of next year.
GE Aviation (Stand 1143) is here promoting its 800-hp H80 turboprop engine, which was certificated by the U.S. Federal Aviation Adminstration in March and already has several applications. Meanwhile, the HF120 turbofan program–for the HondaJet–has progressed slowly.
The Kuznetsov design bureau, part of the United Engine Corporation (ODK), unveiled a new geared turbofan design at the Engines 2000 exhibition in Moscow last month. The PD30 is proposed for an upgrade to the Antonov An-124 Ruslan heavy airlifter, which is currently powered by the Ukrainian Ivchenko Progress D18T. The PD30 could also power Russia’s proposed widebody airliner, known as Airplane 2020.
