EgyptAir flight MS804 crashed into the Mediterranean Sea in May 2016, killing all 66 people on board.
The plane was travelling from Paris to Cairo when the devastating crash occurred.
French authorities have ordered an investigation as to whether a mobile device might have contributed to the plane’s demise.
Investigators have suggested the theory that a pilot charging his iPad in the cockpit could have caused a fire if it overheated.
The probe will focus on an Apple iPhone 6S and iPad Mini 4, both belonging to the first officer.
One source close to the investigation said: “Cockpit plugs are not made for toasters or coffee pots. They’re for professional use.
“At this stage, the combustion or self-combustion of a tablet in the cockpit is the working hypothesis.”
According to Apple, authorities had not contacted the company about the investigation.
The technology giant said there was no evidence to link the EgyptAir crash with any of its devices.
In a statement, Apple explained: “We haven’t been contacted by [Air Transport Gendarmerie] or any authority investigating this tragic event.
“We rigorously test our products to ensure they meet or exceed international safety standards.”
There were 40 Egyptians, 15 French and at least three children on board the doomed flight.
One of the victims was British citizen Richard Osman, a 40-year-old father from Jersey.
