Sherwin-Williams Aerospace Coatings (Booth No. 4547), located in Andover, Kan., introduced several new products during NBAA’12. Its new urethane primer and sanding surfacer (CM0481827) can double as either a traditional sanding surfacer or as a primer. MROs and paint shops can now use one product for two purposes. And the product dries twice as fast as traditional epoxy surfacer technologies. The corrosion-inhibitive urethane primer is also chromate hazard-free and is intended for use on all aircraft.
Duncan Aviation of Lincoln, Neb. (Booth No. 5580), a provider of airframe inspections, engine maintenance, cabin and cockpit systems retrofits, painting and interior work, as well as pre-owned aircraft sales and acquisitions, has acquired several examples of a dry-ice blasting machine to accomplish a specific service bulletin for its Bombardier Challenger customers.
Skyscapes, a new basecoat/clearcoat exterior paint developed by Sherwin-Williams Aerospace, now has two complete coatings, including pretreatment, corrosion protective primer, topcoat and clearcoat. Both are certified with SAE International’s Aerospace Material Specification 3095 (AMS 3095). One system includes Alodine, 483987 primer and Skyscapes basecoat/clearcoat. The second system is Alodine, 483787 chrome hazard-free primer and Skyscapes basecoat/clearcoat.
The U.S. Air Force will gradually lift flight restrictions placed on its Lockheed Martin F-22 Raptor fleet in response to unexplained incidents of hypoxia, or oxygen deprivation, experienced by pilots dating as far back as 2008.
The FAA has issued an airworthiness directive for certain Bombardier Challenger 300s as a result of reports of deformation found at the neck of the pressure regulator body on the oxygen cylinder and regulator assembly (CRA). It requires an inspection to determine if a specified oxygen CRA is installed and to replace affected oxygen CRAs.
Russia’s VSMPO-AVISMA Corp., specialist manufacturer of products made of titanium and aluminum alloys, steel and nickel, and Shanghai Aircraft Manufacturing Co. (SAMC), have signed a long-term purchase contract for titanium forging products for the Comac C919 aircraft program.
Aluminum product developer Constellium wants to increase the percentage of recycled metal it produces for aerospace in a bid to realize both economic and environmental goals. The value of such alloys has grown with the addition of elements such as copper, silver and—critically—lithium. One kilogram (2.2 pounds) of aluminum costs about $2, while one kilogram of lithium—the lightest metal in nature—costs $100.
A seven-month investigation by the U.S. Air Force Scientific Advisory Board into unexplained hypoxia, or oxygen deprivation, incidents experienced by F-22 pilots has not determined the root cause of the problem, the service said March 29. The investigation did produce a number of safety recommendations, and the Air Force continues to study the problem.
Environmental group Friends of the Earth filed a lawsuit against the Environmental Protection Agency (EPA), charging the agency with failure to respond to its 2006 petition requesting the regulation of lead emissions from GA aircraft under the Clean Air Act. In the petition, the group asked the EPA to rule that emissions from aircraft that burn leaded fuel may pose a threat to public health. According to the group, nearly six years later, there has been no final action from the agency.
Aero Sekur (Booth No. 8043), which specializes in safety systems and advanced flexible structures for the aerospace and defense markets, is displaying a range of helicopter safety products at Heli-Expo’12.
