Incident Overview
An aircraft en route from Balikpapan to Kuching experienced a low oil pressure warning light for the left engine. The crew shut down the engine and feathered its propeller. Due to bad weather at Kuching, the captain decided to divert to Simanggang, where the airplane landed safely on one engine.
Engine Failure and Diversion
After touchdown, as the airplane decelerated, the pilot-in-command executed a 180-degree turn and then a backtrack procedure. During this maneuver, one of the landing gear entered soft ground along the runway edge. The crew subsequently filled the left engine oil tank before taking off again for Kuching.
Subsequent Takeoff and Accident
After liftoff, during initial climb, a warning light indicated a technical problem with the feathering system on the right engine. The airplane began to roll left and right, lost height, and crashed in a jungle located 1,400 meters past the end of the runway. The aircraft was totally destroyed upon impact, and all three crew members sustained injuries.
