IHI said the extra cost of inspection would shave 160 billion yen ($1.07 billion) at the operating level for the year ending March 31, 2024. As a result, it now expects an annual net loss of 90 billion yen instead of the previous forecast of 50 billion yen, it said.

RTX last month took a $3 billion charge and told airlines that hundreds of their Airbus jets would be grounded at any one time in coming years to check for a rare manufacturing flaw.

IHI controls about 15% of the GTF programme.
