Investigators successfully retrieved critical black box data 11 days after the crash of Air India Flight 171 in Ahmedabad, using a specialised kit provided by the U.S. National Transportation Safety Board (NTSB) to unlock the damaged memory modules.

NTSB Kit Helps Unlock Black Box Data Post-Crash
In the aftermath of the June 12 crash of Air India Flight 171, which tragically took 260 lives in Ahmedabad, investigators faced challenges extracting data from the heat-damaged black box recorders. Although both the cockpit voice recorder and flight data recorder were recovered promptly, the intense heat prevented initial access to stored data, leaving key moments of the flight unclear.
Toolkit Arrival from the U.S. and Data Recovery
Eleven days after the crash, a specialised data extraction kit arrived from the U.S. National Transportation Safety Board (NTSB). The kit was instrumental in accessing the memory units within the recorders despite sustained damage. Once in India’s Aircraft Accident Investigation Bureau (AAIB) lab, the kit enabled analysts to retrieve vital flight and cockpit audio information, including the pilots’ final “Mayday” transmission.
Why This Matters
-
Reconstruction of final moments: The data provides clarity on engine thrust, switch positions, and cockpit exchange.
-
Investigation depth: Recovery enables a forensic review of whether switch activations, engine failures, or pilot actions led to the crash.
-
Aviation safety improvements: Findings will inform future safety orders, including inspections of Boeing 787 Dreamliners.
