The SaidLe Parisien newspaper quoted an investigation by the Air Transport military police as saying there was a shield above the dashboard.
However, an aviation expert questioned the theory, saying that the cause of the tragedy was still the fault in the avionics cabin under the cockpit, or caused by a short circuit, or

"As a result, investigators note that there is a disturbing parallel relationship between placing these items powered by lithium batteries and triggering alerts during flight," it added.
The stability of lithium batteries has always been the focus of controversy.
Some aircraft are banned and some models in mobile devices are known to overheat and catch fire.
On December 2010, a fire broke out on Air France's flight from Atlanta to Paris, with a lithium battery stuck under its seat. ignited.
On May 2013, another Air France plane from Paris to Sao Paulo, Brazil, also had a small fire on a charging device.

It stated that the Egyptian authorities had failed to provide sufficient detailed information on the conditions under which samples and measures were taken to detect the marks of the explosion.
French investigators did not respond on Friday.
