Ilyushin II-18

Following an uneventful cargo flight from Dubai, the crew started the descent to Colombo-Bandaranaike Airport by night and good weather conditions, using a GPS and DME systems. After being cleared to descend to FL150, the crew received the QNH and QFE values for Colombo: 1009 mb (hectopascals) and 756 mm Hg. The copilot mistakenly input 765 mm Hg instead of 756 mm Hg in the altimeters. At a distance of 14 km from the airport, the aircraft was 60 metres above the sea. It continued to descend until the undercarriage struck the water surface at a distance of 10,7 km from the runway 04 threshold. The captain decided to initiate a go-around procedure but shortly later, at a height of about 60-90 metres, he continued the approach. Assuming the undercarriage may have been damaged, he decided to carry out a belly landing. The aircraft landed 50 metres to the right of the main runway and 450 metres past its threshold. The aircraft then slid for a distance of 2,230 before coming to rest. All seven occupants escaped uninjured and the aircraft was damaged beyond repair.
