Air India replaced the Throttle Control Module (TCM) of the crashed Boeing 787-8 plane twice in the last six years following a directive from Boeing in 2019, sources said on Sunday. The replacement of the TCM twice -- in 2019 and 2023 -- was mentioned in the Aircraft Accident Investigation Bureau's (AAIB) preliminary probe report into the crash that was released on Saturday.

Air India replaced the Throttle Control Module (TCM) twice in its crashed Boeing 787 Dreamliner before the fatal crash, following a Boeing directive. AAIB investigation details.

The two engines on the Air India flight shut down within one second of each other before the Boeing 787 Dreamliner crashed last month in Ahmedabad, India, killing at least 260 people, according to a preliminary report released Friday.
