The FAA is adopting an airworthiness directive (AD) that establishes a new life limit based on a prorated formula for some Sikorsky S-70, S-70A and S-70C components that were previously installed on military helicopters. Some of the parts, including the main rotor hub, main rotor shaft, main rotor spindle nut, rotating swashplate and main rotor gearbox, have been interchanged with military helicopter models with life limits different from those of the civilian version.

Bond Air Services has grounded its EC135 helicopter fleet in the wake of a November 29 accident in which one of the aircraft it operates for local police crashed into a pub in Glasgow, Scotland, killing nine people and injuring 32 others.

The Eurocopter EC135 light twin that crashed into a busy pub on November 29 in Glasgow, Scotland, was intact when it hit the roof, but neither the main rotor nor the fenestron tail rotor were rotating at that time, the UK Air Accidents Investigation Branch preliminary report reveals. The helicopter had been flying for one hour and 33 minutes when the pilot requested clearance to return to Glasgow City Heliport. No further radio transmission was received.

Eurocopter X4

A new artist rendering of the in-development Eurocopter X4 medium-twin helicopter appeared today during a presentation made at the EASA Rotorcraft Symposium in Cologne, showing design changes made since 2011. A horizontal empennage with a two-level lifting surface is visible on the tailboom, forward of the shrouded tail rotor. The fuselage, aft of the cabin, includes a “skirt,” the role of which is still unknown.

As part of its investigation into helicopter crashworthiness and accident survivability, NASA swung a Navy CH-46E like a pendulum before releasing it and allowing it to drop 30 feet to the ground. Onboard sensors and cameras recorded the deformation of the aircraft and the seat structures. Data from the experiment will be used to establish a baseline to test energy-absorbing floor structures to improve passengers’ chances of surviving a similar crash.

If you fly in a helicopter, NASA is interested in saving your posterior.

Contract negotiations between the U.S. Army Aviation Applied Technology Directorate and AVX Helicopter, Bell Helicopter and the Sikorsky/Boeing team–the potential Phase I vendors for the joint multi-role technology demonstrator (JMR-TD)–are nearing completion. Announcement of the awards for a new U.S. Army medium helicopter are planned for September, according to an Army spokesman.

MD Helicopters says it has resolved a reported flexbeam shortage that temporarily grounded a Yorkshire Air Ambulance MD902 in February during an annual inspection. A company spokesman told AIN last month that the supplier of the part, Kaman, had adjusted its production schedule to compensate for an increase in demand for the part over forecast levels and that new flexbeams are now available. MD has had 27 used but serviceable flexbeams available for customers since early this year. MD provided one to Yorkshire in May and that helicopter has been returned to service.

Kamov KA-62

Making its Paris Air Show debut is the Russian Helicopters/Kamov Ka-62, a 6,500-kg mtow, 15-passenger helicopter in the same class as the AgustaWestland AW139, Eurocopter EC155 and Sikorsky S-76 series. The mockup made it first appearance on the international show circuit at last year’s Farnborough Air Show.

Innovation at AgustaWestland, according to Robert Farnese, company market positioning and promotion manager, comprises two elements. “First, you need to have an idea that works,” he told a Paris Air Show audience on Tuesday. “Second, you have to execute that idea.” He then added a caveat: “You must also master the present and have a vision for the future.”
