The FAA issued an emergency airworthiness directive–2013-10-52–for GE90-110B1 and GE90-115B engines on May 16 after two reports of transfer gearbox assembly (TGB) failures prompted in-flight engine shutdowns. Investigations revealed the cause as TGB radial gear cracking and separation. The AD prohibits the operation of any aircraft with either engine installed five days after receipt of the directive.
In response to the powerful tornado that ravaged areas of Oklahoma City on Monday, business aviation charity Sky Hope Network has organized a community relief fund to aid several aviation professionals who lost their homes and also the family of an FAA title examiner who was killed in the tornado. In its first day, the campaign raised nearly $10,000, all of which will be distributed directly to the victims. Donations can be made through June 1 via Sky Hope’s website.
UK-based low-cost carrier EasyJet, Airbus and Nicarnica Aviation plan a final test in August of the Nicarnica-developed airborne-volcanic-object imaging detector in a bid to prevent major air traffic disruption like the one the eruption of Iceland’s Eyjafjallajökull caused in 2010.
Integration of remotely piloted air systems (RPAS, or unmanned air systems) into non-segregated airspace in Europe has moved a step closer with the latest test flight in the Desire project (Demonstration of Satellites enabling the Insertion of RPAS in Europe). The project is funded by the European Space Agency (ESA) and the European Defence Agency (EDA) and led by Indra of Spain.
The massive, gangly Solar Impulse landed at 12:30 a.m. in Phoenix on Saturday, having completed the first leg of the solar-powered airplane’s Across America mission. The flight departed Moffett Airfield in Mountain View, Calif. on Friday at 6:12 a.m. PDT and landed at Phoenix Sky Harbor International Airport on Saturday at 12:30 a.m. MST.
The flight took 18 hours and 18 minutes, all powered by 12,000 solar cells mounted in the wings, driving four 10-hp electric motors and propellers. To fly at night, energy is stored in 881 pounds of lithium-ion batteries.
Terrafugia, the developer of the Transition roadable airplane, says it is designing a hybrid electric/fossil-fuel-powered flying car in the form of a tiltrotor. The TF-X would use electric drive on the ground and for power assist on takeoff. After reaching cruise, the twin tiltrotor pods would fold their propellers flat while a rear-mounted engine-driven shrouded fan would provide propulsion.
When the Transportation Department inspector general conducted a self-initiated audit of the FAA Wildlife Hazard Mitigation Program last year, the office concluded that the agency’s oversight and enforcement activities were not sufficient to ensure that airports fully adhere to p
Despite a number of recent fatal accidents involving post-crash fires blamed on the Robinson R44’s vulnerable aluminum fuel tanks, and despite the Australian Civil Aviation Safety Authority’s (CASA) publishing an airworthiness directive demanding replacement with improved flexible bladder versions, many operators have failed to comply.
A federal judge has allowed buffalo herding by helicopter, in response to a lawsuit filed by an environmentalist group that had obtained a restraining order against such operations in Yellowstone National Park last year, alleging the practice adversely affects grizzly bears. Helicopters have been used for more than a decade to steer wandering bison back into Yellowstone each spring.
Eurocopter Japan has delivered a Eurocopter AS365N3 Dauphin retrofitted with a high-speed, real-time satellite transmission system to the country’s Fire and Disaster Management Agency. The helicopter satellite communication system enables direct transmission to relay satellites, without being interrupted by the helicopter’s moving rotor blades. Mitsubishi Electric developed the system, intended for use when ground-based networks are unavailable.
