Rolls Royce announced on June 11, 2018, that the durability issue already detected on its Trent 1000 Package C engines also affected “a small number of high life Package B engines”. The British manufacturer reached out to authorities and Boeing in order to conduct more thorough investigation.

The Trent 1000 engine was designed to power Boeing 787 Dreamliner, along with the General Electric GEnx engine. The launch customer of the B787, All Nippon Airways (ANA), detected unusual corrosion on the compressor blades, resulting in early wear and cracking on its Trent 1000 engines in early 2016.

In April 2018, Rolls Royce determined that the Package C was the one affected. But after conducting inspections on the Package B engines, Rolls Royce discovered similar defects. The manufacturer announced it would now proceed to an in depth inspection of the fleet B.

Rolls Royce has been struggling with the repairs of the Package C engines that are equipping about 25% of all Dreamliners currently in service, according to Boeing. It will take an estimated three years to replace all  blades, for an estimated cost of $454 million.

This new problem comes at a time when Rolls Royce is suspected by the Sunday Times to cut 4,000 jobs in its main plant of Derby, United Kingdom. The company refused to comment “on current media speculation” according to BBC.

Along with its 2017 results, the British manufacturer announced on March 7, 2018, it would undergo a restructuring of its operations, aiming to “move to a considerably simplified staff structure, with fewer layers and greater spans of control across the group”. The restructuring plan is to be presented on June 15, 2018.
