Business jet manufacturers are quietly progressing toward more-electric architectures, where electricity replaces hydraulic and pneumatic power in systems such as brakes, landing gear or even control-surface actuation. This avoids the use of environmentally unfriendly hydraulic fluids and ultimately should help reduce fuel burn.

Cessna has chosen Smiths Aerospace to provide the hydraulic actuation and display systems for the new Citation CJ3 jet announced here at NBAA on Monday. Initial deliveries of the equipment will begin in 2004 with full production to start two years later. Smiths (Booth No. 4357) expects the deal to result in $20 million in sales through the life of the program.

Canada’s National Research Council has won a patent on “an active and adaptive rotor-blade control system called Smart Spring,” which is designed to reduce the noise and vibration when rotor blades interact with the vortices shed by the tip of the preceding blades. Previous engineering approaches, according to NRC, have attempted to alter the varying aerodynamic load on the blades to reduce the onset of this vibration.

Hawker Beechcraft Beech 99, Billings, Mont., May 19, 2007–The NTSB determined the probable cause of this landing accident to be the failure of the nosegear actuator and the nosegear collapse.

At 4 a.m., the Alpine Aviation aircraft was substantially damaged in night VMC when the gear collapsed during the landing roll. The ATP-rated pilot, the sole occupant, was not injured.

The FAA issued a special airworthiness bulletin on October 7 alerting operators of the Raytheon Beech Premier I that the agency has determined that the jet’s flap actuators are “nonconforming” parts, fabricated from material that might be subject to “brittle failures at cold temperatures.”

A malfunction of the flight-control system played a role in the 2005 fatal crash of a Sikorsky S-76 in Estonia, according to an interim report issued by Estonian investigators. The final report is scheduled to be released next spring.

The ongoing investigation into the August 10 fatal crash of an S-76C+ in the Baltic Sea has led the NTSB to ask the FAA to take “urgent” action on several recommendations directed at the twin-turbine helicopter’s hydraulic systems. The aircraft’s flight data recorder showed that the helicopter “pitched up and rolled to the left, followed by a series of rotations to the right before striking the water,” killing all 14 people aboard.

Bell/Agusta’s BA609 looks nothing like the finished article in the VMSIL. In place of a fuselage and wings, the tiltrotor’s systems, interfaced with an aircraft flight-simulation host computer, are spread across three separate areas in the lab.
