Thai Airways is intending to claim financial compensation from British manufacturer Rolls-Royce, after the airline had to ground its Dreamliners fleet due to Trent-1000 engine problems, according to Bangkok Post.

The issues with blade coating in Rolls-Royce Trent-1000 engines were found in early 2017. The engines power the global fleet of Boeing 787 Dreamliners, amounting to around 160 aircraft in total. The company has estimated that it will take roughly three years to replace the blades in all the affected engines.

Thai Airways, whose four of six Dreamliners remain grounded due to engine issues, are expecting the situation to improve next month and return to normal operations in September 2017. However,  Bangkok Post quotes THAI acting president Usanee Sangsingkeo stating that the airline expects compensation for the damage arising from the issues.
