History of the Flight
On 21 January 2020, a Cessna 208B EX aircraft registered PK-SNP, operated by PT. Smart Cakrawala Aviation, was conducting an unscheduled passenger and cargo flight from Mozes Kilangin International Airport (WABP), Timika, Papua, to Kenyam Airstrip (WAYC), Kenyam, Papua. The aircraft carried two pilots and 12 passengers. The Pilot in Command (PIC) acted as Pilot Monitoring (PM), while the Second in Command (SIC) acted as Pilot Flying (PF).
At 0248 UTC (1148 local time), under daylight conditions, the aircraft departed from Timika. No aircraft system malfunctions were recorded or reported prior to departure. The planned cruising altitude was 9,000 feet, but due to traffic, the pilots changed to 7,000 feet.
At 12:25:02 local time, the Cockpit Voice and Data Recorder (CVDR) recorded the PM broadcasting on the Traffic Information Broadcast by Aircraft (TIBA) frequency that the aircraft was joining left downwind for runway 22. The airspace over Kenyam was Class G with no air traffic services.
At 12:25:58 local time, the CVDR recorded that while on final approach for runway 22, the PM instructed the PF to set the aircraft speed between 70 and 84 knots and to pitch down. Approximately one second later, the stall warning activated for two seconds, followed by an Enhanced Ground Proximity Warning System (EGPWS) callout of "MINIMUM MINIMUM."
At 12:26:19 local time, the PM reminded the PF to pitch down and reduce engine power to idle. At 12:26:23, the PM advised the PF not to hesitate to idle the engine power. One second later, the stall warning activated again for one second. The PM then pitched the aircraft up, and at 12:26:25, the CVDR recorded the sound of touchdown. The aircraft touched down approximately 150 meters before the beginning of runway 22. The PM felt the tail section impact the ground, followed by the main landing gears.
The aircraft bounced to the right and touched down outside the runway pavement, with the right landing gear contacting first. The PM recovered the aircraft to the runway centerline. After returning to the centerline, the PM stated "I have control" and continued taxiing to the apron. No injuries occurred.

- Left and right main landing gear struts bent
