Narrative:
The Ilyushin 76 was part of an air relief operation following an earthquake in Armenia on Dec. 7, 1988. The aircraft flew into the side of a mountain while on approach to Leninakan.
The crew had used an incorrect altimeter setting (734 mm Hg instead of 634 mm Hg). This resulted in an erroneous altitude indication that was 1100 metres above the actual altitude.
The crew were tired, since they did not have sufficient rest. They made several relief flights the day before.


Classification:
Insufficient rest / fatigue
Controlled Flight Into Terrain (CFIT) - Mountain
