The affected Rolls Royce Trent 1000 engines are used on ANA's Boeing Co 787 Dreamliner jets, the Japanese airline told reporters on Wednesday.

A compressor problem in the Trent 1000 package C engine has already led to planes being grounded by airlines such as British Airways, Virgin Atlantic [VA.UL] and Air New Zealand. In June, Rolls Royce said it had found the same issue on a "small number of high life Package B engines".

ANA has been conducting inspections on Trent 1000 package C engines under instruction from Japan's transport ministry, with an expansion of inspections to include package B engines leading to the flight cancellations, the airline said.

In total 136 engines are affected, said ANA, the world's biggest 787 operator by fleet size.

Progress on a fix for the affected engines has been hampered by a global shortage of replacement parts, the airline said.
