The FAA is revising an earlier proposed airworthiness directive for the Eurocopter BO105A/C/LS/LS A-3 and 105S. The earlier AD proposed inspecting for debonding of the erosion protective shell (abrasion strip) on the leading edge of each main rotor blade. This SNPRM proposes to revise those inspection requirements by identifying specific dates of replacement of the applicable parts and identifying a specific inspection method to discover debonding of an abrasion strip.
The first flight of the Quest Helicopters AVQ light twin has slipped by half a year, to “August or September” this year. A prototype aircraft is said to be almost ready to fly, even as the company shifts its focus from the four-seater to a larger 10- to 15-passenger version.
American Eurocopter is doing more than just showing off its offerings at its booth during the NBAA Convention. The company will also offer flying demonstrations of its EC135 and EC155 helicopters during the show.
Three contenders for the U.S. Army’s as-yet-undefined armed aerial scout (AAS) requirement–Bell Helicopter, Boeing and EADS North America–have just completed a series of flight demonstrations for Army evaluators who are studying alternatives to the aging OH-58D Kiowa Warrior for manned reconnaissance. They reported the results at the Association of the U.S.
The FAA has issued an airworthiness directive for the Eurocopter EC155B, EC155B1, SA365N1, AS365N2 and AS365N3 requiring visual inspection of the tail-rotor hub for a crack and removal if one is found. The AD is prompted by reports of cracks on two tail-rotor hubs. These actions are intended to prevent the tail rotor from jamming, which could lead to reduced control or loss of control of the helicopter.
Russian Helicopters has received an order for 18 Ka-226TG light twins from NefteGazAeroCosmos, a “research and production center” linked to Russian oil and gas giant Gazprom. Six helicopters are scheduled for delivery next year and the remaining dozen in 2014.
Russian Helicopters, the company that parents Russia’s two helicopter design bureaus and five helicopter-manufacturing plants, is moving forward with a new-generation helicopter that is intended to replace the hugely successful Mil Mi-8/17 series. The new project, dubbed Rachel (Russian advanced commercial helicopter), clearly has many military applications.
American Eurocopter’s blade shop in Grand Prairie, Texas, is a busy place. The 20 craftsmen repair and refurbish 1,000 helicopter main and tail rotor blades every year. That translates into 95 percent of all Eurocopter blade work in the U.S.
Much of the work is done by hand. “It is a slow process,” acknowledges shop manager Jim Tully. “It would be nice if we could find a way to go faster, but it has to be done the same way. With fiberglass, it wouldn’t take long to scrap out a blade completely” if a mistake were made.
A test aircraft assigned to Bell Helicopter’s XworX research-and-development division crashed Tuesday morning 10 miles from Avalon, Texas. The two-pilot crew was uninjured.
Wreckage video taken by a Dallas television station shows that the twin-engine Bell 214ST was flying a main-rotor system that had five blades when pilots made an emergency landing in a field and then gently rolled onto its right side. The video does not show any remains of the tail rotor.
A global team of research organizations is quietly working on an active rotor blade in which distributed piezo-electric actuators can change blade twist almost continuously over the course of one blade revolution. Partners can be found in the U.S., Europe and Asia. A full test campaign is scheduled for next year.
