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.
GE Aviation won the Game-Changing Technology Implementation award last week at the 2013 Manufacturing Leadership Summit for its Integrated Vehicle Health Management (IVHM) technology. Designed to reduce delays, cancellations and unscheduled maintenance as initially implemented on the G650 business jet, IVHM continuously manages and analyzes data throughout the flight, creating a set of health information for the engines, avionics, power, cabin and other aircraft systems.
GE Honda Aero Engines has announced that its 2,095-pound-thrust HF120 turbofan intended initially for the HondaJet is nearing completion of certification tests and is on track for delivery of the first entry into service engines before the end of 2013. “We now have a line-of-sight for certification and we are gaining experience on the fleet,” said Terry Sharp, GE Honda Aero president. “We are gearing up for the production environment, which should come by the end of the year.”
GE Aviation is no stranger to the business aviation world. Its CF34 engines have powered Challengers for 30 years, while its larger engines are used by Airbus Corporate Jets and Boeing Business Jets (through its CFM joint venture with France’s Snecma). It is currently bringing the HF120 turbofan (in the GE Honda Aero joint venture with Honda Aircraft) and Passport 20 (for Bombardier’s Global 7000/8000) to the marketplace.
GE Aviation began running its third and final eCore demonstrator last month in preparation for application on the Passport business jet engine and the new CFM Leap family, as well as a potential basis for the still orphaned NG34 turbofan development.
