Eurocopter announced yesterday that it will upgrade the American Eurocopter plant in Columbus, Miss., to accommodate final assembly of the AS350, which it said is the top-selling civil helicopter in the U.S. market. AS350 production is expected to start at the plant in the fourth quarter of next year and will ramp up to 60 of the light single-engine helicopters annually by 2016.

NASA researchers recently conducted drop tests of a Boeing Vertol CH-46 Sea Knight to test improved seats and seat belts. They recorded the crash from more than 350 data channels as the helicopter, suspended by cables, was dropped into a bed of soil from 30 feet up. Just before impact, pyrotechnic devices released the suspension cables from the helicopter to allow free flight toward impact with a forward speed of approximately 30 mph.

AgustaWestland and Russian Helicopters signed an agreement last week at the MAKS airshow in Moscow for the joint design and development of a new light single-engine helicopter. The 50-50 joint program was first announced by the partners about a year ago.

The preliminary assessment of the 5,600-pound helicopter’s technical design is expected to be completed “in the next few months.” It is being designed for the worldwide market and a “wide range” of applications, the companies said.

The tiltrotor test rig (TTR) development team at NASA Ames Research Center was honored today with a 2013 NASA Group Achievement Award. Team members include personnel from NASA Ames, Bell Helicopter and Triumph Aerospace Systems. The TTR is a joint project among NASA, the U.S. Army and U.S. Air Force to develop a new large-scale system that can test prop-rotors up to 26 feet in diameter at speeds up to 300 knots, allowing for advanced research on tiltrotors and other rotorcraft concepts.

Mitsubishi has contracted with Sikorsky to acquire 11 S-76Ds for search-and-rescue operations by the Japan Coast Guard. Meanwhile, in China, Citic Offshore Helicopter has ordered two S-92s for offshore oil transportation. Sikorsky plans to deliver the new S-92s in December next year and March 2015. In another Chinese deal, Sikorsky and Zhuhai Helicopter announced a contract for four Sikorsky S-92s to be used for offshore missions.

The Eurocopter X3 technology demonstrator flew at 255 knots in level flight, an unofficial record for a helicopter, on June 7. It also reached 263 knots in a dive. “It’s no exaggeration to say that the X3 is clearly in its element at high speeds,” said Hervé Jammayrac, Eurocopter test pilot.

The Eurocopter X3 hybrid made its record-breaking speed run just 10 days before the opening of the Paris Air Show, so it was not surprising that the EADS company brought both the unique aircraft and its crew to the Le Bourget biennial event. On June 7, the X3 flew at 255 knots in level flight and 263 knots in a dive, besting the previous record set by the Sikorsky X2 in September 2010 (250 knots level and 260 knots in descent).

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.

Eurocopter EC225 operators in the North Sea will be provided with modification kits that allow return to flight.

The EASA approved the interim solution–a combination of vibration monitoring, inspections and part modification–that Eurocopter devised for the EC225 to address main gearbox (MGB) lubrication issues after the type experienced two controlled ditchings last year. The manufacturer’s fix is intended to reduce the likelihood of an undetected crack, leading to in-flight rupture and ditching, to one per billion flight hours. At issue is the bevel gear vertical shaft, a part that is critical to main gearbox lubrication.
