In January, Pratt & Whitney achieved a major milestone in its campaign to become a certified supplier of spares for CFM International’s CFM56-3 turbofans when it ran the first engine test containing parts it had re-engineered and manufactured. The event marked one of the final steps toward certification and delivery of the first P&W-manufactured CFM56-3 parts to the ground-breaking service’s launch customer, United Airlines.

CFM International, the engine manufacturing joint venture between General Electric and Snecma of France, is forging ahead with a range of advanced engine studies as part of its leading edge aviation propulsion (LEAP56) program.
Snecma is progressing with its plans to develop a turbofan in the 10,000-pound-thrust class. Last October, the French manufacturer revealed plans to enter the business jet engine market. Design of the Silvercrest powerplant is well under way and the core should run later this year.

The simultaneous dual flameout of a Garuda Indonesia Airlines 737 and its subsequent ditching on Jan. 16, 2002, has led the NTSB to issue two recommendations targeting FAA turbofan rain and hail ingestion engine certification standards. The CFM56-3-B1 engines failed when the aircraft flew through a thunderstorm and encountered “extremely heavy” precipitation and hail on the approach.
CFM International has announced that New Delhi, India, will be the location for the company’s fourth aircraft engine maintenance training school. It is slated to open in 2010.
Engine manufacturers are showing renewed interest in the 10,000-pound-thrust segment. They see the aging of the General Electric (GE) CF34-3B, the only engine in production in the class, and at least two companies–Snecma and Pratt & Whitney Canada–are eyeing future large business jets, the size of the Bombardier Challenger 600 series, as potential applications. Meanwhile, GE is modernizing the CF34-1 for the Challenger 601.
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.
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.
Malaysian discount-fare airline AirAsia finally chose an engine type for the 60 Airbus A320s it ordered in two batches last December and in March. CFM International will supply its CFM56-5B as specified under a firm order signed here yesterday for 120 engines and nine spares valued at some $750 million at list price.
