India’s deadliest plane crash in more than decade is set to send shock waves through the aviation insurance industry and trigger one of the country’s costliest claims, estimated at around $475 million.

An Air India Boeing 787 Dreamliner crashed just seconds after takeoff from Ahmedabad Airport on June 12 with 242 people onboard, out of which, 241 people died.

The Air India Flight 171 crash in Ahmedabad, which claimed 241 lives, may lead to one of the largest aviation insurance payouts in history—estimated at $475 million. Experts warn the disaster could drive up aviation insurance premiums and impact global reinsurers.
