The Japan Transport Safety Board has concluded its investigation into the overheating of the lithium-ion main ship battery aboard a Boeing 787 last year without reaching a definitive conclusion on the cause. However, the report, issued on Thursday, said that “inappropriate” testing might have contributed to the Jan. 16, 2013 incident, which led to a worldwide grounding of the Dreamliner fleet until Ethiopian Airlines resumed service on April 27 that year. It also pointed to low temperatures as a possible culprit due to lithium metal’s tendency to form deposits on a battery’s electrodes in such conditions.
Aireon, a joint venture involving Iridium Communications and Nav Canada, the country’s private-sector civil air navigation service provider, has announced a plan to provide free real-time global emergency flight tracking for any ADS-B equipped aircraft. The Aireon Aircraft Locating and Emergency Response Tracking service will be available to authorized search-and-rescue operations, soon after the completion of the Iridium Next satellite constellation in 2017.
Metallized Carbon (Metcar), a manufacturer of oil-free, self-lubricating, carbon-graphite materials for severe-service lubrication applications, has announced its carbon-graphite bushings are available for use in gear pumps that pump aviation fuel for aircraft engines. The carbon-graphite bushings, which are used to support both the drive gear shaft and the idler gear shaft, are preferred for that application because they can use aviation fuel as the bushing lubricant.
The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration issued safety regulations July 31 for transporting lithium batteries by air, a move intended to harmonize existing U.S. rules with international standards. The Air Line Pilots Association praised the action as recognition of the serious risk unregulated shipments of lithium batteries pose to all who depend on air transportation.
Pratt & Whitney and Alcoa recently have revealed that the fan blades of the PW1000G family of geared turbofans will consist mainly of aluminum alloy–an industry first.
Parker Aerospace is here at FIA 2014 (Hall 4 Stand A18) highlighting a variety of technology developments and improvements in its customer support provisions.
Kubick Aviation has purchased its larger competitor, Superior Aviation, at Ford Airport in Northern Michigan, to become the sole aviation services provider on the field, which sees approximately 20 operations a day. Kubick moved from its 4,700-sq-ft facility (which was since sold to an aeromedical provider) to the former Superior location, which has a 3,000-sq-ft terminal and 22,000 sq ft of hangar space capable of sheltering aircraft up to the size of a Citation Sovereign.
An international field research campaign led by Airbus and NASA has gathered a wealth of data on icing conditions in convective weather, especially on ice crystals that cause engine icing. The eight-week effort ended in March in Darwin, Australia, and the researchers expect to publish their report early next year. The partners in the project hope to gain a better understanding of icing conditions that will allow them to devise mathematical models for equipment manufacturers to use when designing detection systems.
GAMA praised the U.S. House Appropriations Committee’s “continued strong support” for reform of the Part 23 aircraft certification process and the transition away from leaded avgas. “We are especially pleased by the committee’s emphasis on improving the certification process at the FAA,” said GAMA president and CEO Pete Bunce.
Vision Systems Aeronautics (Booth 2809) of Lyon, France is unveiling here at EBACE 2014 two new products: Energia, a self-powered dimmable window; and VisiStream, a solution for Wi-Fi inflight entertainment (IFE) and connectivity.
