A Deraya British Aerospace Bae ATP, registration PK-DGB performing a cargo flight from Jayapura to Wamena (Indonesia) with 2 crew, landed on Wamena Airport's runway 33 in heavy rain at about 15:15L (06:15Z) but skidded on landing losing directional control and came to a stop with the left main and nose gear collapsed at the edge of the runway. There were no injuries, the aircraft sustained substantial damage including the fracture of the left hand wing however.

An observer on the ground reported that just prior to the arrival of the aircraft weather deteriorated rapidly when a rain shower moved over the aerodrome associated with gusts and decreasing visibility that reduced to about 1-2km in the moderate to heavy rain. The aircraft joined final to runway 33 following a left downwind, but did not appear stabilized while descending through about 400 feet AGL. The aircraft was offset to the left of the extended runway centerline. The power was cut, the aircraft banked steeply right, the group of observers on the ground already expected the aircraft to crash at that point. The aircraft was recovered, touched down "with momentum", while skidding to the right the left main gear collapsed and the left hand propeller contacted ground causing the aircraft to spin around until it stopped in its final position near taxiway D. The airport remains closed during Mar 5th until the aircraft can be removed.

On Mar 5th 2015 the aircraft was moved off the runway into a southwest corner of the new apron and the aerodrome reopened.

No Metars are available for Wamena, the local weatherstation reported at 15:00L: Temperature 22 degrees C, dew point 17 degrees C, humidity 67%, QNH 1003hPa, visibility 9km, easterly winds at 22kph/12 knots, light to moderate rain.

AIP Indonesia still publishes an aerodrome chart of 2010 as current on their website even though that chart is already outdated, runway has been lengthened at the northern end, runway 15 threshold moved north, and the runway is now about 2200 meters long. The chart as published by AIP Indonesia does not feature the taxiway labels, these were added by AVH.
