The Microturbo e-APU60, a new concept in auxiliary power units (APUs), recently completed a 150-hour block test and is progressing toward certification, Microturbo, a Safran Group company, announced at the NBAA Convention. “These tests gave us the opportunity to validate the reliability and the endurance of this new concept, meeting our expectations and those of our first customer, AgustaWestland,” said Pierre-Yves Morvan, CEO of Microturbo. “This milestone represents a significant step forward for the program.”

The FAA has issued an airworthiness directive for the Cessna 750’s auxiliary power unit DC generator prompted by overvoltage events. The AD requires replacing the APU generator control unit to prevent DC generator overvoltage events, which could result in smoke in the cockpit and loss of avionics and electrical systems. On June 25 a notice of proposed rulemaking was issued proposing the APU generator control unit be replaced and the public was given the opportunity to comment.
Efforts to reduce the thousands of gallons of jet fuel now being burned each year just to move aircraft to and from runways are very much in evidence at the 2012 Farnborough International airshow. No fewer than four new products vying for the attention of airline and airport managements, including efforts by Israel Aircraft Industries (IAI), L-3, Safran/Honeywell and WheelTug, and they each have taken a different approach.
Hamilton Sundstrand has signed an agreement with Fokker Services to provide spare parts in support of Fokker repair work at its Amsterdam facility. The purchase contract, which runs through 2016, is valued at $33.2 million. It covers “integrated drive generators and other equipment” for aircraft built mainly by Airbus, Boeing, Bombardier and Fokker.
The U.S. company has also announced three maintenance and support deals with airlines here at the show:
Turbomeca subsidiary Microturbo (Stand 1543) has completed the first flight tests of its new auxiliary power unit (APU) for the AgustaWestland AW189 helicopter. In-flight start has been demonstrated already, and the test unit has also successfully restarted one of the main engines in flight. “The e-APU60 is performing accordingly with our ambitious goals,” said Pierre-Yves Morvan, Microturbo’s CEO.

Dallas Airmotive’s regional turbine center at Singapore’s Seletar Aerospace Park celebrated its official opening with a ceremony on Monday led by general manager Francis Lee. The center will offer authorized Honeywell services for auxiliary power units (APUs) and business aviation engines, and respond to aircraft-on-ground (AOG) situations.
Push-back tugs and taxiing aircraft with engines powered up may well, in a few years, be seen as remnants of the past. Two exhibitors here at the Singapore Airshow are studying electric motors that would drive the aircraft’s wheels on the ground.
The AgustaWestland AW189 medium twin helicopter will be the first civil application for Microturbo’s e-APU, an auxiliary power unit that delivers essentially electric power.
Aircraft auxiliary power units (APUs) can now remain on while radiation checks are conducted on aircraft entering the country, as long as the exhaust vents for those units are eight feet above the ground or higher. NBAA said the shutdown requirement emerged when Customs agents began screening all aircraft arriving in the U.S. using radiation isotope identifier devices, causing “significant ground delays.”
