EASA Adds Trent 1000-TEN IP Turbine to Previous ADs
EASA has added Trent 1000-TEN intermediate-pressure turbine to previous ADs of the Rolls-Royce engine.
The Rolls-Royce Trent 1000 TEN offers a 10:1 bypass ratio, the highest of any Trent engine. It first flew on a Boeing 787 in 2016. Boeing also offers the General Electric GEnx on the 787.

A new European Union Aviation Safety Agency (EASA) Airworthiness Directive (AD) covering Rolls-Royce Trent 1000 (T1000) engines expands previous maintenance requirements and, for the first time, draws the T1000-TEN variant into the powerplant's continuing saga of compressor and turbine in-service issues. Taking effect on June 25, EASA AD 2019-0135 covers intermediate-pressure turbine (IPT) blade replacement in more than 30 variants among T1000-series engines (except those modified in production or since entering service).
