On 25 October 2022 a Cessna C208B aircraft, registration PK-RVA was being operated by PT. Reven Global Airtranspor (RGA) for an unscheduled cargo flight.

During flight preparation in Timika, the engineer informed the pilot to perform brake burned in after replacement right brake lining backplate without detail instruction or guidance on how to perform. The pilot applied light breaking several times while taxing then continued the flight Timika – Ilaga – Timika.

After landed in Timika, the pilot reported to the engineer that right brake pedal was spongy compare to the left side. The engineer suggested this condition commonly occurs after replacement of brake lining and the brake pedal pressure will be equal after several burned-in or brake usage. No maintenance action taken by the engineer.

The aircraft departed from Timika at 2348 UTC (0848 LT) and cruised at altitude of 13,000 feet. On board on this flight were 2 pilots and cargo consisted of six motorcycles and some groceries. The Pilot in Command (PIC) acted as Pilot Flying (PF) and the Second in Command (SIC) acted as Pilot Monitoring (PM).

During the descent passing about 8,700 feet, the pilot contacted the airport personnel to report the position. The airport personnel informed the pilot that the weather at Ilaga was clear.

About 0913 LT, the aircraft landed within the touchdown zone of Runway 25. The pilot applied brake and the pilot felt the aircraft tend to veered to the left. The pilot recovered by released pedal brake and apply right rudder to turn the aircraft to the apron.

The aircraft continued to roll to the end of the runway and impact to the runway barrier and stopped about 75 meters from the end of Runway 25. The pilot shut down the engine then evacuated the aircraft. No person was injured in this occurrence.
