Narrative:The Boeing 737-300 Freighter, registration PK-BBY, operated on a scheduled cargo flight. At 12:34 the aircraft departed from Jayapura-Sentani Airport (DJJ), bound for to Wamena Airport (WMX).
On board this flight were two pilots, and 14,610 kg of cargo. The captain was as pilot flying while the first officer who was under line training acted as pilot monitoring.
At 15:37 hours, when the aircraft approaching PASS VALLEY, the Wamena Tower controller provided information that the runway in use was runway 15 and the wind was 150/18knots, QNH 1003 and temperature 23°C. At 15:46, the pilot reported position on final for runway 15 and Wamena Tower controller provided landing clearance with additional information of wind 150/15 knots and QNH 1003.
One minute later, the aircraft touched down about 35 meters before the beginning of runway 15 with a vertical acceleration of 3.68 G and stopped at about 1500 meters from the runway threshold. The left main landing gear collapsed and the left engine scratched the runway surface.
No one was injured on this occurrence.
Probable Cause:
Contributing Factor:
The large thrust reduction during the windshear resulted in rapid descend and the aircraft touched down with 3.683 G then collapsed the landing gear that had strength degradation.
