TOKYO, Oct 25 (Reuters) - Japan's IHI forecast on Wednesday a big swing to the red this business year due to the impact of additional inspections announced last month by Pratt & Whitney parent RTX Corp for the Geared Turbo Fan (GTF) engine system.
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 a 50 billion yen profit, 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. ($1 = 149.8400 yen) (Reporting by Kaori Kaneko Editing by Chang-Ran Kim)
