Rolls-Royce has completed testing of the latest build of a research two-shaft engine core, known as “Core 3/2d,” as part of the E3E (efficiency, environment, economy) program. The core evaluation campaign ends without a previously planned endurance test, however. E3E technology forms the basis of Rolls-Royce’s Advance2 future two-shaft engine program, which targets entry into service in 2018.

An airworthiness directive has been issued for all Honeywell TFE731-20R, -20AR, -20BR, -40, -40AR, -40R, -50R and -60 turbofan engines. It was prompted by a report of a quality escape of about 8,000 second-stage low-pressure turbine (LPT2) rotor blades manufactured by Honeywell’s Chihuahua, Mexico, manufacturing operation since 2009. This AD requires removing and inspecting certain LPT2 rotor blades. Cost of the fix is $3,480.
