A Flight Options Beechjet 400A (N691TA) yesterday afternoon experienced a dual-engine flameout en route from Indianapolis International Airport to Marco Island Airport, Fla., while on a positioning leg. The crew declared an emergency and landed safely at Jacksonville International Airport. This marks the second such Beechjet incident at the Cleveland-based fractional provider.
Investigations into two accidents involving Eurocopter AS 350A and AS 350B2 helicopters led the NTSB to determine that the hydraulic pump drive belt (P/N 704A33690004) prematurely failed in flight. Additionally, an inquiry into the FAA’s Service Difficulty Report database found that 43 failures and/or replacements of hydraulic pump drive belts with that part number occurred from February 1995 to the present.
French engine manufacturer Snecma has revealed plans to develop a turbofan engine to power business and regional jets. It has started developing a core engine demonstrator called the SM-X that, if a full development program is launched, would yield a powerplant producing between 8,500 and 10,000 pounds of thrust. Ground testing of the core is set for the second half of next year.
Four reported incidents of in-flight loss of hydraulic fluid led to an emergency AD being issued Friday for the 139 in-service Premier Is. None of the incidents led to any mishaps, according to Raytheon Aircraft. The problem has been traced to the failure of a hydraulic tube assembly in the left engine. The directive requires a visual inspection of the affected part before further flight and thereafter at intervals of 50 hours.
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.
The National Air Transportation Association (NATA) warned its members of a new requirement imposed by the Alabama Department of Agriculture and Industries Heavy Weights and Measures Division. According to NATA, the state has decided to apply legal standards for self-serve auto fuel pumps to aviation facilities.
Diversified industrial manufacturer Eaton Corp. is showing its range of expertise in the aerospace field here in Paris, highlighting its recent developments in the civil realm, such as a 5,000-psi hydraulic power generation and fluid conveyance system used in the Airbus A380.
European engine manufacturers are joining forces on Vital, a research program co-funded by the European Commission that aims to reduce carbon dioxide (CO2) and noise emissions by commercial aircraft.
Winglets increase efficiency by reducing lift-induced drag. They do this by relocating and diminishing the vortex at the wing’s tip, resulting in lower fuel burn, higher cruise speed and longer range.
The General Electric/Pratt & Whitney Engine Alliance partnership was last month awarded certification of the GP7200 by the U.S. Federal Aviation Administration (FAA) and is now preparing for its first flight powering the giant Airbus A380 airliner.
