Embraer on February 20 obtained FAA certification and JAA recommendation for its 70- to 78-passenger Model 170 regional twinjet, some 18 months later than originally planned. The delay has been particularly irksome for Embraer 170 launch customers US Airways and Alitalia. The certification includes a Honeywell fly-by-wire system, to which Embraer earlier attributed to program delays.

Few sounds are louder than a jet aircraft at takeoff.
The decibel level of a climbing jet engine at full power can be higher (140 dB) than that of a chain saw (110 dB) or ambulance siren (120 dB), according to the National Institute for Occupational Safety and Health.
But relief may be a toggle away, if recent university research finds its way into aircraft cockpits.
Raytheon Airline Aviation Services and Pratt & Whitney Canada have announced the availability of a 9,000-hour overhaul interval for the PT6A-67D engines installed on the Beechcraft 1900D. Most 1900s must undergo overhauls at between 6,000 and 8,000 hours.
Pratt & Whitney Canada recently reached the rated takeoff thrust of 1,350 pounds in sustained ground runs of its new PW615 turbofan engine, which will power the Cessna Citation Mustang. Cessna expects to receive the first engine shipsets early this year. Certification of the engine is planned by the end of 2005, and Cessna expects to certify the Mustang in the third quarter of 2006.
Rolls-Royce is now exploring future engine technologies that, although challenging, are key to the ambitious Advisory Council for Aerospace Research in Europe (ACARE) goals for 2020 in terms of nitrous oxides (NOx) and carbon dioxide (CO2) emission cutting and noise reduction. These technologies range from heat exchangers to shape memory alloys and magnetic bearings.
General Electric Aircraft Engine Services’ facility at Nantgarw in south Wales is preparing to overhaul and repair the Engine Alliance’s GP7200 powerplant for the Airbus A380 super-large airliner. The program is part of a $10 million budget that will support infrastructure for the new engine over the next three to five years.
CFM International has launched a new technology development program, LEAP56, that aims to ensure successors to its market-leading CFM56 engines can meet future airline demands for improved fuel consumption and reliability along with tougher environmental regulations.
Pratt & Whitney Canada plans to build a brand-new engine for Bomardier C Series line of single-aisle commercial airliners. The Canadian airframer confirmed the powerplant selection at the Paris Air Show yesterday during an unveiling of partial cabin mockup on display at Le Bourget.
Europrop International (EPI) performed the first TP400-D6 engine control and monitoring system (CMS) test in Villaroche late in May, the consortium announced just before the show. The TP400 is the turboprop engine designed for the Airbus A400M military transport aircraft.
GKN Aerospace has won approval from Snecma Services to repair and overhaul CFM56-5B fan blades. The authorization covers the restoration of the blades’ overall length and midspan shrouds. Critical to the engine’s efficient operation, the blade length and midspan shroud dimensions erode over time.
