Airbus flew its new A320neo on its first test mission on Thursday, marking the start of a 3,000-hour flight-test program scheduled to lead to certification and entry into service in next year’s fourth quarter. Powered by a pair of Pratt & Whitney PW1100G geared turbofans, MSN6101 took off from Toulouse-Blagnac Airport in France at noon local time.

The engineering team for GE Aviation’s new GE9X turbofan has completed development of the new carbon fiber composite material that will allow the powerplant for Boeing’s new 777X airliner to use fewer, thinner fan blades. Combined with the use of new composite case technology developed for the GEnx program, the engine will be around 1,000 pounds lighter than its predecessor.

Rolls-Royce here announced the first run of the Trent XWB-97 turbofan on Tuesday. Selected as the sole engine for the higher-thrust version for the Airbus A350-1000, The 97,000-lb-thrust Trent XWB-97 will begin test flights in 2016. Entry into service is pegged for 2017. The turbofan’s increased thrust is obtained by a combination of new high-temperature turbine technology, a larger core and advanced fan aerodynamics, Rolls-Royce (here at Hall 4 Stand H3) said.

The FAA is superseding emergency AD 2014-12-52 for all Honeywell TFE731-4, -4R, -5AR, -5BR, -5R, -20R, -20AR, -20BR, -40, -40AR, -40R, -40BR, -50R and -60 turbofans. It required a review of the engine logbook maintenance records to determine if any affected engines are installed and also prohibited operation of an airplane with two or more affected engines that have second-stage low-pressure turbine (LPT2) blades with fewer than 250 operating hours since new.
