The FIA says it will analyse "every aspect" of Romain Grosjean's Bahrain GP crash and "collaborate with all parties involved" in the dramatic accident.
Grosjean's 53G impact with the barriers last Sunday led to the Haas' survivor cell piercing the Armco and to a raging inferno that were cause for concern according to F1 boss Ross Brawn.
From the Haas' trajectory and resistance and how it absorbed the formidable energy upon impact, to the efficiency of the barriers and the performance of Grosjean's personal safety equipment, the FIA's forensic investigation will leave no stone unturned as it breaks down every stage or component of the event.
The role of the track marshals and F1's medical team will also be assessed.
"As with all serious accidents, we will analyse every aspect of this crash and collaborate with all parties involved," said FIA safety director Adam Baker.
"With so much data available in F1, it allows us to accurately determine every element of what occurred and this work has already begun.
"We take this research very seriously, and will follow a rigorous process to find out exactly what happened before proposing potential improvements."
The governing body's investigators will rely on data gathered from "various video streams, including a high speed camera which faces the driver and films at 400 frames per-second to reveal in slow motion what happens to him during the accident".
"Data will also be gathered from the in-car accident data recorder, which will reveal the speed and forces on the car, and the in-ear accelerometers that are moulded to fit inside a driver's ear canal to measure the movement of his head in a crash," said the FIA.
The investigation is expected to take around 6-8 weeks to complete before findings are made public.
All information and data will be added to the FIA's world accident database while the governing body's Serious Accident Study Group [SASG] will use the relevant information across other FIA disciplines for the purpose of improving safety.
The FIA lost no time to kick off its investigation, with its technical delegate Jo Bauer and head of competitor safety Nuno Costa visiting Haas on Monday to examen the remains of Grosjean's Haas VF-20.
"They were here yesterday, if I say a whole day maybe I exaggerate, but at least six hours, Jo Bauer and Nuno Costa , they were inspecting everything," Haas team boss Guenther Steiner said on Tuesday.
"But they have done with the car, we can take the car back, they have done all their work, but there is no outcome yet. For sure when they do these investigations they can come up with things that can be developed for the future, to be even safer.
"As far as I know they have no issues with our car at all, everything was to regulations."
