Tokyo - ANA, largest airline in Japan on the basis of fleet size, might cancel 113 domestic flights between the 6th and the 12th of July because of the Trent 1000 engine inspections of its Dreamliners.

All Nippon Airways (ANA) is currently investigating whether it has to delete flights because of a regulation issued by the JTSB, Japan Transport Safety Board, on June 14. The board has ordered further inspections for the Rolls-Royce Trent 1000 engines.

Problems with Trent 1000 engines of the British manufacturer have forced airlines worldwide to lease replacement aircraft or cancel flights. Last month, the European Aviation Safety Authority (EASA) had also announced that it would issue a new order for these engines.

ANA, the world’s largest fleet owner of Boeing 787, has to bring 136 units to the workshop including spare engines and has to ground Jets. The Japanese carrier has 64 Dreamliners (36 787-8 and 28 -9) in its fleet.

On April 17, The FAA had issued an Airworthiness Directive requiring Airlines to conduct inspections on Trent 1000 Package B engines because of the cracks that were found in the roots of the blades of the Intermediate-Pressure Compressor (IPC).

Almost half of the ANA's Dreamliner fleet is equipped with engines from Package B.
