Cessna 208B Runway Overrun at Sela Airstrip, Papua (PK-SNR)

Incident Overview and Flight History On 26 December 2020, a Cessna 208B aircraft registered PK-SNR, operated by PT. Smart Cakrawala Aviation, was conducting an unscheduled passenger and cargo flight from Nop Goliat Dekai Airport (WAVD) to Sela Airstrip in Papua, Indonesia. The aircraft departed Dekai at 0347 UTC (1247 local time) in daylight conditions, carrying two pilots and ten passengers. The Pilot in Command (PIC) served as the Pilot Flying, while the Second in Command (SIC) acted as the Pilot Monitoring. The flight proceeded uneventfully, climbing and cruising at an altitude of 7,000 feet until the approach to Sela began. ## Approach and Landing Sequence The approach to Runway 21 at Sela was conducted via the left downwind. The pilot selected 20 degrees of flaps before joining the final approach, at which point the flaps were extended to the full-down position. At 13:03:15 local time, the Cockpit Voice and Data Recorder (CVDR) recorded the sound of the aircraft touching down when it was 160 meters from the beginning of the runway. The pilots recalled that the main landing gear made contact with the runway first, followed by the nose wheel. ## Post-Touchdown Events and Outcome Following touchdown, the PIC applied maximum brakes and set the power lever to the BETA range position. The pilots observed that the aircraft did not decelerate as intended. Approximately 30 meters from the end of the runway, the PIC set the power lever to the maximum REVERSE position. Despite these actions, the aircraft stopped and impacted higher ground at the end of the runway. The PIC subsequently shut down the engine, and the SIC assisted with the evacuation of the passengers. No injuries were reported in this occurrence. ## Investigation and Safety Actions The preliminary report was published by the Komite Nasional Keselamatan Transportasi (KNKT) on 24 February 2021. The report is based on initial investigations conducted in accordance with Annex 13 to the Convention on International Civil Aviation Organization, the Indonesian Aviation Act (UU No. 1/2009), and Government Regulation (PP No. 62/2013). Following the incident, Smart Aviation implemented safety actions, which the KNKT acknowledged as relevant to improving safety. However, the KNKT noted that additional safety issues remained to be addressed and issued safety recommendations to the Directorate General of Civil Aviation. The investigation was ongoing at the time of the preliminary report's publication.
