This paper presents the results of investigations of the thermal action on sheet specimens of the skin of an aircraft from aluminum alloy AMn with a wall thickness from 2 to 6 mm of the pulse A-component (with a normalized amplitude of 212 kA and an action integral of 2.07 x 106 A2 . sec) and of the long C-component (with a normalized amplitude of 846 A and duration of 1000 msec) of the electric current of the artificially-initiated lightning. It has been shown that the thermal stability of the above sheet specimens is determined by the long C-component of the lightning current causing in them active electrical erosion. The experiments performed and the calculations of the thermal state of the sheet specimens indicate that to provide a thermal lightning resistance of the skin and electromagnetic safety of flights of aircrafts under the conditions of direct action on them of lightning electric discharges, the wall thickness of their skin from aluminum alloy AMn or from another material with similar thermophysical characteristics should be no less than 4 mm.
