This is not an accident investigation report.

About forty minutes after take-off, the aircraft entered a zone of strong turbulence and lightning. After flying for twenty minutes in this weather at FL210 lightning struck the aircraft, causing fire on the right wing which separated, along with part of the left wing. The aircraft crashed in flames into mountainous terrain. Structural failure occurred because of the loads imposed on the aircraft flying through a severe thunderstorm, but also because of stresses resulting from the manoeuvre to level out the aircraft.
