Families of those who perished in the June 12 Air India crash have called for the immediate public release of the aircraft’s two flight recorders, warning that prolonged delays are undermining their confidence in the official investigation.

The tragedy claimed the lives of all 241 passengers and crew aboard the London bound Boeing 787 Dreamliner, which went down shortly after take-off from Ahmedabad, western India. An additional 19 people on the ground were killed when the aircraft crashed into a densely populated area, causing widespread destruction.

On Friday, representatives of the victims’ families issued a joint statement urging the Aircraft Accident Investigation Bureau (AAIB) to make both the cockpit voice recorder (CVR) and flight data recorder (FDR) data public. They argued that transparency was vital to prevent speculation, misinformation, and what they described as “a slow erosion of public trust.”

“Our loved ones deserve justice, and justice begins with the truth,” the statement read. “We cannot remain in the dark while crucial evidence is withheld.”

A preliminary AAIB report, released earlier this month, revealed that fuel supply to the aircraft’s engines was cut off moments before the crash.

The report stopped short of assigning blame, but cited CVR transcripts indicating a puzzling exchange in the cockpit: one pilot reportedly asked the other why fuel had been cut, to which the second pilot denied doing so.

The AAIB has said the investigation remains ongoing, with international aviation safety experts assisting in the probe. However, family members say the wait for answers has been “agonising” and insist that the recorders hold the key to understanding the disaster.

A memorial service for the victims is planned in Ahmedabad later this month, where relatives say they will renew calls for full disclosure and accountability.
