India's Aircraft Accident Investigation Bureau (AAIB) has refused to disclose cockpit voice recordings and other critical data from Air India Flight AI-171 [1].

The decision to withhold these records prevents families of victims and parallel investigators from accessing primary evidence regarding the cause of the crash. This lack of transparency has created a tension between the need for legal confidentiality and the public demand for accountability.

The AAIB said it will not release cockpit voice recordings, air traffic control audio, transcripts, or witness statements [1]. These materials are protected by law and specific confidentiality rules, according to the bureau [1]. Because of these legal constraints, the agency said the data cannot be shared with a parallel probe or the families of those affected [1].

The crash occurred in Ahmedabad in May 2022 [1]. While some updates were reported in 2023, the full details of the event remain under wraps. The AAIB said the final report is expected to be issued in October 2026 [1].

This refusal comes as investigators continue to analyze the sequence of events leading to the accident. The bureau said the integrity of the investigation depends on the restricted nature of the black box data and related testimonies [1]. By keeping these records private, the AAIB aims to ensure that the final conclusions are based on a controlled review process rather than fragmented public disclosures.

Despite the pressure for immediate answers, the agency has maintained its timeline. The investigation has spanned several years, and the bureau said it will adhere to its current schedule for the final report [1].

The AAIB said the final report is expected to be issued in October 2026.

The AAIB's refusal to share data highlights the strict legal framework surrounding aviation investigations, where confidentiality is prioritized to prevent premature conclusions. However, the extended timeline—stretching from a 2022 crash to a late 2026 report—may increase scrutiny over the efficiency of India's aviation safety audits and the transparency of its investigative processes.
