The FIA will launch an investigation into how Kevin Magnussen's headrest became detached following his crash during the Belgian Grand Prix.
The Renault driver lost the rear of his car as he exited Eau Rouge, spinning, before coming to rest in the Raidillon tyre barrier.
The high-speed crash registered at 42G as his car decelerated heavily, with his cockpit headrest flying off in the process.
Although Magnussen walked away from the accident with minor bruising and a cut to his ankle, the governing body is keen to investigate how and why the headrest, which is supposed to provide additional padding for their helmet to reduce the risk of injury, became detached.
The U-shaped piece is secured with two horizontal pegs behind the driver's head and two quick release fixings, which can be easily removed without the need for tools, as the headrest needs to be removed for a quick driver extraction.
The FIA recently installed high-speed cameras in all 22 cars which face the driver, that recording could prove pivotal in determining how it became loose and how to avoid it happening in future.
