Rolls-Royce has begun informing Boeing 787 operators of an accelerated inspection regime for Trent 1000 TEN engines after checks revealed that a “small population” of the powerplants suffered from earlier than anticipated high-pressure turbine (HPT) blade deterioration, the British engine manufacturer said Wednesday. The company established the accelerated inspection regime in cooperation with the European Aviation Safety Agency (EASA), Rolls-Royce noted, adding that the Cologne, Germany-based body will issue an airworthiness directive in addition to its own service bulletin.
