NEW DELHI: (Jul 14) 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, according to sources.

TCM includes fuel control switches, which have come to focus in the ongoing probe into the fatal crash as these switches were cut off immediately after takeoff of the ill-fated London-bound Dreamliner VT-ANB that crashed in Ahmedabad on June 12.

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. It also said the TCM replacement was not linked to the fuel control switches.
