A Trigana Air Service Boeing 737-300 freighter, registration PK-YSY performing flight IL-7321 from Jayapura to Wamena (Indonesia) with 3 crew and 15.3 tons of cargo (fuel, rice, sugar), landed on Wamena's runway 15 at 07:35L (22:35Z Sep 12th) but touched down very hard in a nose high attitude, left the left main gear behind, the right main gear collapsed, and the aircraft slid on nose gear, belly and both engines to a halt at and partly beyond the right hand edge of the runway. There were no injuries, the aircraft sustained substantial damage.

A ground observer reported, the cloud base was about 150-200 feet, the aerodrome features no instrument approaches and thus is strictly visual approach only. A Trigana Boeing 737-300 landed successfully a few minutes earlier, then PK-YSY was seen breaking out of cloud, correcting to the right and pitching down to descend towards the runway. The aircraft subsequently touched down very hard in a nose high attitude, the left main gear separated from the airframe, the right main gear collapsed, and the aircraft skidded on nose gear, both engines and the belly to a halt right of the right hand edge of the runway past the new apron. The airport is currently closed.

Indonesia's Ministry of Transport reported flight TGN-7321/IL-7321, carrying 15,353 kg of freight consisting of drums of Diesel as well as sugar, rice and other goods, was involved in an accident at Wamena at 07:35L, when the aircraft slid to a halt at the right hand side of the runway. There were no injuries. The condition of the runway surface is being assessed, the accident is being investigated by Indonesia's NTSC/KNKT.
