The black box of the ill-fated plane was sent to France to the ATR company for decoding. But the transcript analysis of the contents has failed to find the real cause of the crash.

According to decoding report , both engines of the aircraft were running 100 per cent fine when the plane took off from Chitral. Also one of the engines was still working when the plane crashed.

The black box data indicates that no effort was made to land the aircraft before the crash, so investigations are trying to determine why the plane crashed despite the fact that one of its engines was properly working.

The weather conditions on the day of the crash were also normal and the pilot had extensive experience of flying in the northern areas, which led investigator to consider other possibilities.
