Crash analyst notices detail in new Air India footage that ‘changes everything’

He said the detail was not noticeable in other clips


After analysing footage of Air India’s flight 171, which tragically crashed just moments after takeoff, a crash analyst noticed how the Ram Air Turbine (RAT) had been deployed.

Last week, Flight AI171 from Ahmedabad to London Gatwick crashed with 242 people on board, killing 241 passengers and a further 38 people on the ground. Only one survivor, Ramesh Viswashkuma, was saved from the tragic accident, with experts suggesting it was because he sat in seat 11A. Investigations into the crash are still underway.

In a YouTube video uploaded on June 15, commercial pilot and crash analyst Captain Steeeve detailed a few of the things he spotted in the footage.

Why is Air India’s RAT deployment important?

Numerous videos have circulated online, showing the Air India flight leaving the runway just moments before the crash. Captain Steeeve managed to get hold of another angle, analysing it in a YouTube video that has since recieved over nine million views and counting.

In the clip, the crash analyst highlighted the Ram Air Turbine (RAT) on Air India’s flight 171, which is used in dire circumstances to provide pressure for the aircraft. While RAT deployment can assist a plane in the event of engine failure, it is not designed to operate at such low altitudes.

“Many airplanes have it. It is just behind the wing on the right side of the airplane, there is a little door that holds it in,” he explained.

“It looks like a little Evinrude motor, it’s a little two-bladed prop. Its function is to provide electrical and hydraulic pressure for the aircraft in an extreme emergency.”

Specifically, on aircraft such as Air India’s Boeing 787 Dreamliner, the RAT is deployed under one of three circumstances: A massive electrical failure, a huge hydraulic failure, or a dual engine failure. The official cause of the crash is yet to be announced.

“A RAT makes a unique sound, it sounds like a propeller airplane going by, or a real high-pitched squeal. It is essentially spinning at the speed of sound to generate the energy, electrical and hydraulic that it needs to,” he added. “If you weren’t looking at it, it sounded like a single-engine prop airplane just flew by.”
