Just 40 seconds in the air — that’s all Air India Flight 171 managed before crashing into a crowded neighbourhood in Ahmedabad, in one of India’s most puzzling aviation disasters in recent memory.
Now, investigators have the daunting task of piecing together exactly what went wrong in those terrifying seconds after takeoff. The Boeing 787 Dreamliner, carrying 242 people and nearly 100 tonnes of fuel, lifted off at 13:39 local time but quickly sent out a mayday call — its final message before plunging down in flames.
What Could Have Gone Wrong?
Captain Kishore Chinta, a veteran crash investigator, calls this “the rarest of the rare” — a controlled flight crashing into terrain almost immediately after takeoff. Experts are scratching their heads:
- Did both engines fail simultaneously? Maybe bird strikes or contaminated fuel?
- Were the flaps improperly set, making it hard for the heavy plane to lift off in the heat?
- Was there a maintenance slip-up?
- Or did something happen inside the cockpit, like a crew mistake cutting fuel to the engines?
The investigation will explore all these questions and more.
Cracking the Black Box
Investigators rely heavily on the plane’s black boxes — the cockpit voice recorder and flight data recorder. These devices capture everything from radio calls and cockpit sounds to engine performance and flap positions, providing a second-by-second account of the flight.
One of the first clues might come from the engines themselves. If they were spinning at full power when the plane hit the ground, that suggests one story; if not, it’s a very different one.
The High-Tech Puzzle
Today’s flight data recorders are a far cry from those used decades ago. Instead of tracking just a few parameters, they log hundreds — even thousands — of details every second. This high-tech data helps investigators build a detailed timeline and understand exactly what the plane was doing in those critical moments.
A Global Effort
The investigation is led by India’s Aircraft Accident Investigation Bureau (AAIB), with experts from Boeing, engine maker GE, Air India, and regulators from the US and UK all pitching in. Early results from checks on other Air India 787 planes showed no major safety issues.
What Happens Next?
Wreckage is carefully collected and examined — every bolt, wire, and blade is scrutinized. The team will also review maintenance logs, pilot training records, and even recent flight history to find any clues.
While the preliminary report is expected within 30 days, understanding the full “why” behind the crash may take up to a year or more.
Even though the mystery remains, modern technology and global teamwork give hope that answers will soon emerge — helping make flying safer for everyone.
