Recently there have been a small number of incidents of phones and tablets catching fire on board aircraft worldwide. Causes included crushing in the aircraft seat mechanism.
Operators of aircraft with seats featuring electrical or mechanical means of adjusting position should consider briefing passengers to take care of their personal electronic devices.
Passengers should also be told that, if this happens, they should not move the seat and inform the cabin crew, who can assist. Cabin crew procedures should be amended accordingly, including an explanation that assistance from engineering may be needed on the ground.
