Incident Overview
On 23 May 2023, a Cessna 208B with registration PK-BVU, operated by PT Asi Pudjiastuti Aviation (Susi Air), was conducting scheduled passenger flights in the Sumatera area. The aircraft was operated under dual pilot control. The planned flight sequence was Padang–Rokot–Padang–Mukomuko–Bengkulu–Enggano–Bengkulu–Muko-Muko–Padang.
Pre-flight and Departure
At approximately 0600 local time, the pilots were transported from their accommodation to Padang airport. En route, they reviewed the applicable Notice to Airmen (NOTAM) and Notice to Crew (NOTOC) for the planned schedule. No notices relevant to the occurrence were found. The flight departed Padang at 0717 LT under visual flight rules, with five passengers on board. The Pilot in Command (PIC) acted as Pilot Flying and the Second in Command (SIC) as Pilot Monitoring. Padang Tower instructed the flight to contact Padang Radar, which cleared the aircraft to climb to 10,000 feet and proceed direct to Rokot.
Approach and Landing
At 0735 LT, approximately 32 nautical miles from Padang, ATC instructed the flight to contact Rokot ACO on frequency 122.4 MHz. The PM attempted to contact the ACO but received no response. The PF then advised making a position broadcast, considering that no flight information service was available. The PF noticed a new runway with designation 14-32 near the existing Runway 17-35 at Rokot Airport. The pilots overflew the airport at 1,000 feet to assess runway conditions. Weather was clear with good visibility. Neither pilot observed cross markings on either runway or any obstructions. The PF noted that Runway 14-32 appeared longer and had clearer markings (threshold, designation, touchdown zone) than Runway 17-35. The PF decided to land on Runway 17.
However, at 0759 LT, the aircraft touched down on Runway 14. During the landing roll, the pilots observed several construction materials on the runway strip and no ground personnel at the apron. They realized they had landed on an undesignated runway. No injuries were reported, and the aircraft was undamaged.
Investigation Status
The Komite Nasional Keselamatan Transportasi (KNKT) is continuing the investigation. No analysis or conclusions have been published in this preliminary report. Safety actions and recommendations have been issued to the airport operator, ATS provider, aircraft operator, and the Directorate General of Civil Aviation.
