Bombardier Aerospace recently completed a non-temperature-restricted bleedless auxiliary power unit starting test, following a 10-hour cold soak at -40 degrees F and using a starter/generation system and lithium-ion battery system. The Safran Microturbo e-APU system included a starter generator and power electronics from Thales and a Saft Li-ion battery system. The prototype equipment was designed for business jets, Bombardier said. The tests were conducted at the Safran Turbomeca cold-chamber facility in Pau, France.
The UK Air Accidents Investigation Branch (AAIB) investigation into the fire on board a Boeing 787 operated by Ethiopian Airlines at London Heathrow Airport on July 12, 2013, discovered improper wiring of the lithium metal battery that powered the aircraft’s Honeywell 406AFN fixed emergency locator transmitter (ELT). According to an AAIB special bulletin published last week, the investigation concluded that the battery had been incorrectly wired to the ELT during the manufacturing process.
The corporate and business aviation sectors have posted strong safety numbers, recording few accidents, but that is no reason for operators to become complacent. That was the message from NTSB member Robert Sumwalt at the Flight Safety Foundation/NBAA annual Business Aviation Safety Summit (Bass), held in late April in San Diego.
The National Transportation Safety Board on May 22 issued five safety recommendations to the FAA related to the evaluation and certification of lithium-ion batteries, as well as the certification of new technology. The recommendations evolved through the ongoing investigation of a Jan. 7, 2013, lithium-ion battery fire aboard a Boeing 787 parked at Boston Logan Airport.
Mid-Continent Instrument (Booth No. 3636) has received FAA and EASA approval for its new True Blue Power TB17 advanced lithium-ion engine start and main ship battery. The TB17 is the first lithium-ion battery to receive certification for general aviation applications. The 16-pound battery is designed for light turbine and piston aircraft and weighs up to 45 percent less than lead-acid or nicad batteries. The company says the TB17 is designed for less maintenance, lower cost and longer life than traditional batteries.
The Rechargeable Battery Association (PRBA) urged the U.S. Department of Transportation (DOT) in a January 12 letter to promptly complete its review of pending rules designed to bring the U.S. into compliance with ICAO on methods of transporting lithium batteries aboard civil aircraft. Citing the prohibition of lithium batteries aboard passenger aircraft, the PRBA said it sees no reason why the government should delay rule harmonization any longer.
The Japan Civil Aviation Bureau is investigating what caused smoke to pour from a main battery vent aboard a Japan Airlines Boeing 787 on January 14. The manufacturer developed a fix for its lithium batteries after last year’s fleet grounding, so the work now is focused on whether the fix actually worked and prevented a larger fire, or whether the smoke and the associated battery alarms were indicative of some other issue.
On September 26, Aircare Solutions Group (Booth No. N1736) held a grand opening for its new emergency procedures training facility in Long Beach, Calif. The new facility is equipped with Aircare’s Facts VIII full-motion cabin simulator, the company’s largest, as well as hypoxia awareness trainers, a walk-in fire trainer and BBJ slide and exits.
Mid-Continent Instrument’s True Blue Power division introduced two new lithium-ion main-ship batteries yesterday, designed for jets, turboprops, piston airplanes and helicopters. The new 28-volt batteries come in two sizes: the TB44 (44 ampere hours) and TB17 (17 ampere hours), and can be seen at Mid-Continent’s NBAA exhibit (Booth No. C10040). These new batteries, which will be certified and ready for deliveries in the fourth quarter this year, are first being offered to aircraft manufacturers and not yet to the aftermarket.
The Air Line Pilots Association (ALPA) hopes that testing the U.S. Federal Aviation Administration is conducting will identify a limit for the number of lithium batteries that can be safely transported by cargo aircraft.
