Japan's ANA Holdings says it intends to seek compensation from Rolls-Royce after its ANA - All Nippon Airways (NH, Tokyo Haneda) unit was forced to cancel more than a dozen flights last month following issues with the Trent 1000 engine.

Earlier this year, ANA said it had experienced several instances where Trent 1000 powerplants, used exclusively on its B787 fleet, had suffered performance failures mid-flight. A Rolls-Royce investigation later attributed the incidents to some of the engines' intermediate pressure turbine blades failing to meet their expected lifespans.

An exercise was launched last month to replace the affected parts resulting in ANA cancelling eighteen flights. The disruption has reportedly cost the airline JPY82 million yen (USD807,325) thus far with more expected to come given it expects the entire process to take up to three years to complete. ANA operates over fifty B787-8 and B787-9 twinjets all of which are powered by the Trent 1000.

As such, according to sources who spoke to Bloomberg, ANA may seek compensation in the form of discounts on future purchases or free parts, rather than cash.

The value of the potential claims was not disclosed.
