Aviation thrives on innovation, and Aerospace Technologies Group of Boca Raton, Fla., and Aviation Glass & Technology in the Netherlands are doing exactly that.

ATG is a leader in the design and manufacture of aircraft window treatments and shades, and Aviation Glass recently introduced a 1.7-mm clear glass that is up to 25-percent lighter than the typical 3-mm polycarbonate currently in use. The two companies formed a partnership and expect to “conquer new frontiers with its revolutionary glass solution.”

Eurocopter says it has made significant progress in solving the main gearbox issue that has blighted the EC225 medium twin since last May, reporting that a third test campaign at its headquarters in Marignane, France “is establishing” the cause of crack initiation.

Eurocopter attributes the issue to “a combination of factors” leading to a degradation of the vertical shaft’s fatigue resistance. The helicopter manufacturer has excluded any “abnormal dynamic overload.” Failure of the bevel gear shaft causes a loss of lubrication.

Bombardier relies heavily on a new factory in Belfast, Northern Ireland, run by its Short Brothers subsidiary for CSeries wing production. Built with the help of £60 million ($90 million) from the UK government, the 600,000-sq-ft plant on the northwest side of Belfast City Airport’s runway specializes in new resin transfer infusion (RTI) fabrication techniques refined at other Bombardier plants in the region, in Dunmurry and Newtownabbey.

Duncan Aviation Lincoln’s nondestructive testing (NDT) team has added weekend shift coverage to help meet shorter turn-time demands while enhancing customer service. “We needed to add a weekend shift to serve our internal and external customers better and meet the shorter turn times they were requesting,” said Marty Lincoln, Duncan Aviation’s accessories manager. The addition calls for both new hires and the repositioning of existing team members.

The FAA is proposing to supersede an existing airworthiness directive for the Agusta A109E that requires reducing the tail rotor (T/R) blade life limit, modifying a T/R hub and grip assembly, re-identifying two T/R assemblies, clarifying the never-exceed speed (Vne) limitation and reducing the inspection interval. The OEM has since redesigned a T/R grip bushing that reduces the loads, which caused cracking on the T/R blades.

Bowman Plating, a chemical processing company located in Compton, Calif., was sentenced in U.S. District Court, Los Angeles, for providing false statements related to the chemical processing of aircraft parts sold to commercial aviation companies and to the Department of Defense. Bowman was ordered to pay a fine of $500,000, a special assessment of $1,200, and to serve three years of probation.

The ever-increasing use of composites in aerospace has given rise to technological advances not only in aerodynamics but in so-called green disciplines. Engineers have studied different processes for decades, and recycled composites from Boeing 787s have already found their way onto recreational products such as kayak paddles.

Hawker 4000 on Viper

Reaction to the collapse of negotiations between Hawker Beechcraft and Superior Aviation Beijing seems to be less that of surprise and more about the inevitability of the dead end the two companies reached.

The FAA is adopting a new airworthiness directive for all Agusta A109S and AW109SP helicopters. A fatigue crack found in the left elevator assembly along the riveting of the upper skin to the fourth rib on an Agusta A109S prompted the AD. The airworthiness directive requirements are designed to detect a crack that could lead to a failure of the elevator, reduced maneuverability of the helicopter, and subsequent loss of control of the helicopter.
