Sikorsky S-76A, Santa Maria, Calif., June 27, 2008–The pilot’s misjudgment of clearance from an object during a hovering turn for landing was the probable cause of the crash of an S-76A operated under Part 135 by Arctic Air Service, the NTSB has determined. Contributing to the accident was an inadequately marked heliport surface and the close proximity of an obstruction to the landing area.

Eurocopter is working on a compound helicopter with a single main rotor, a fixed wing with two propellers in puller configuration and no tail rotor, probably in response to Sikorsky’s X2 and Bell/Agusta Aerospace’s BA609 Tiltrotor, which are attempts to create a faster rotorcraft. The Marignane, France-based helicopter manufacturer in May last year filed a patent application at the U.S. Patent and Trademark Office.

The Eurocopter EC 145 is carving a growing niche among EMS helicopter operators for one main reason: cabin space. The EC 145 features 213 cu ft of cabin space and 50.8 sq ft of tracked flat floor space with enough room, in a pinch, for two patient litters and three medical attendants.

Van Horn Associates (Booth No, 2012) said it completed flight testing of a new composite carbon fiber spar and skin tail rotor blade for the Bell 206B earlier this month. The company reports that the new blade increases high-altitude hover performance and decreases required pedal pressure compared to the original equipment blades. Van Horn estimates that fatigue and acoustic testing on the new blade will be completed by early summer.
