Sriwijaya Air as a scheduled passenger flight from Hasanuddin Airport (WAHH), Makassar, South Sulawesi to Rendani Airport (WAUU), Manokwari, West Papua, with one transit stop at Domine Eduard Osok Airport (WASS) Sorong, West Papua. The flight was uneventful since the first departure from Makassar until commencing the approach at Manokwari. At 0815 LT (2315 UTC), the aircraft departed Sorong to Manokwari. On board in the flight were two pilots, four flight attendants and 146 passengers. On this flight, the Second in Command (SIC) acted as Pilot Flying (PF) and the Pilot in Command (PIC) acted as Pilot Monitoring (PM). At 2331 UTC, the pilot made first contact to Rendani Tower controller and informed that the aircraft was descending from FL 230 (altitude 23,000 feet) and requested the weather information. The Rendani Tower controller informed to the pilot that the wind was calm, ground visibility 6 km, cloud FEW CB 1,400 feet, temperature and dew point 26/25°C. At 2336 UTC, Rendani Tower controller instructed to the pilot to descend to 11,000 feet and to report when on Visual Meteorological Condition (VMC). At 2338 UTC, the pilot informed that they were on VMC condition and passed altitude 13,000 feet while position was 32 Nm from ZQ NDB (Non-Directional Beacon). Rendani Tower controller instructed to fly maintain on visual condition, fly via overhead, descend to circuit altitude, join right downwind runway 35, and to report when overhead Manokwari. At 2344 UTC, the pilot reported that the aircraft was over Manokwari and Rendani Tower controller informed to the pilot that the visibility changed to 5 km. Two minutes later Rendani Tower controller instructed to the pilot to continue approach and to report on right base runway 35. At 2349 UTC, at approximately 600 feet, the PIC as PM took over control by called “I have control” and the SIC replied “You have control”. A few seconds later the pilot reported that the aircraft was on final runway 35, and Rendani Tower controller instructed to the pilot to report when the runway 35 insight. The pilot immediately replied that the runway was in sight and acknowledged by Rendani Tower controller who then issued landing clearance with additional information that the wind was calm and the runway condition wet. At approximately 550 feet, the PIC instructed the SIC turn on the wiper and reconfirmed to SIC that the runway was in sight. Between altitude 500 feet to 200 feet, the EGPWS aural warnings “Sink Rate” and “Pull Up” sounded. At 2350 UTC, the aircraft touched down and rolled on runway 35. The spoiler deployed and the pilot activated the thrust reversers. The crew did not feel significant deceleration. The aircraft stopped at approximate 20 meters from the end of runway pavement. After the aircraft stopped, the PIC commanded “Evacuate” through the Passenger Address (PA) system. The Rendani Tower Controller saw that the aircraft was overrun and activated the crash bell then informed the Airport Rescue and Fire Fighting (ARFF) that there was an aircraft overrun after landing on runway 35. All the flight crew and passengers evacuated the aircraft and transported to the terminal building safely.

On 12 April 2017, a Cessna C208 aircraft registered PK-FSO was being operated by PT. Spirit Avia Sentosa (FlyingSAS) for unscheduled cargo flight. The flights of the day scheduled for the aircraft were Mopah Airport (WAKK) – Tanah Merah Airport (WAKT) – Oksibil Airport (WAJO) – Tanah Merah – Oksibil – Tanah Merah. The estimated time departure of first flight from Mopah Airport to Tanah Merah was 0800 LT and the flight departed at 0848 LT, on board the aircraft were two pilots and seven passengers. The aircraft arrived in Tanah Merah at about 0943 LT. At 1012 LT, the flight departed from Tanah Merah to Oksibil. About 10 Nm from Oksibil the pilot contacted the Oksibil tower controller to get air traffic services and landed at 1044 LT. The flight then departed from Oksibil to Tanah Merah at 1058 LT and arrived about 1126 LT. These flights were single pilot operation. At 1144 LT on daylight condition, the aircraft departed Tanah Merah with intended cruising altitude of 7,000 feet. Prior to departure, there was no report or record of aircraft system malfunction. On board the aircraft was one pilot, 1,225 kg of general cargo and 800 pounds of fuel which was sufficient for about 3 hours of flight time. After departure, the pilot advised Tanah Merah tower controller of the estimate time arrival at Oksibil would be 1224 LT. At 1149 LT, the pilot advised Tanah Merah tower controller that the aircraft position was about 10 Nm from Tanah Merah and passing altitude of 3,500 feet. The Tanah Merah tower controller acknowledged the message and advised the pilot to monitor radio communication on frequency 122.7 MHz for traffic monitoring. At about 29 Nm from Oksibil, the PK-FSO aircraft passed a Cessna 208B aircraft which was flying on opposite direction from Oksibil to Tanah Merah at altitude 6,000 feet. At this time, the aircraft ground speed recorded on the flight following system was about 164 knots. The Cessna 208B pilot advised to the pilot on radio frequency 122.7 MHz that the PK-FSO aircraft was in sight. The pilot responded that the aircraft was maintaining 7,000 feet on direct route to Oksibil. At 1230 LT, the Oksibil tower controller received phone call from the FlyingSAS officer at Jakarta which confirming whether the PK-FSO aircraft has landed on Oksibil. The Oksibil tower controller responded that there was no communication with the PK-FSO pilot. The Oksibil tower controller did not receive the flight plan for the second flight of the PK-FSO flight. Afterwards, the Oksibil tower controller called Tanah Merah tower controller confirming the PK-FSO flight and was informed that PK-FSO departed Tanah Merah to Oksibil at 1144 LT and the reported estimate time of arrival Oksibil was 1224 LT. At 1240 LT, the Oksibil tower controller received another phone call from the FlyingSAS officer at Jakarta which informed that the FlyingSAS flight following system received SOS signal (emergency signal) from PK-FSO aircraft and the last position recorded was on coordinate 04°48’47.7” S; 140°39’31.7” E which located approximately 6 Nm north of Oksibil. Afterwards, the Oksibil air traffic controller advised the occurrence to the Search and Rescue Agency. On 13 April 2017, at 0711 LT, the PK-FSO aircraft was found on ridge of Anem Mountain which located about 7 Nm north of Oksibil.

On 25 December 2016, an ATR 72-600 aircraft registered PK-WGW was being operated by PT. Wings Abadi Airlines (Wings Air) as a scheduled passenger flight from Husein Sastranegara International Airport (WICC), Bandung to Ahmad Yani International Airport (WAHS), Semarang with flight number WON 1896. On board the aircraft were two pilots, two flight attendants and 68 passengers. There was no report or record of aircraft system malfunction prior to the departure. The aircraft departed from Bandung at 1734 LT (1034 UTC). The Pilot in Command (PIC) acted as Pilot Flying (PF) and the Second in Command (SIC) acted as Pilot Monitoring (PM). The flight from departure until commenced for landing approach was uneventful. At 1112 UTC, at night condition, the air traffic controller of Semarang Approach unit (approach controller) informed to all traffic that the rain was falling over the airport and the pilot confirmed whether the rain was heavy and was replied that it was slight rain. At 1115 UTC, the flight held over waypoint KENDA for separation with another aircraft and maintained altitude of 4,000 feet. Two minutes later, the flight was approved to descend to altitude of 3,000 feet. At 1118 UTC, the approach controller issued clearance for RNAV approach to runway 13 and advised the pilot to report when leaving waypoint KENDA. One minute later, the pilot reported leaving waypoint KENDA and the approach controller instructed to continue approach and to contact to the air traffic controller of Semarang Tower unit (tower controller). At 1120 UTC, the pilot advised to the tower controller that the aircraft was on final and the runway was in sight. The tower controller instructed to continue the landing approach and advised that the surface wind direction was 190° with velocity of 15 knots, altimeter setting 1,008 mbs and the runway was wet. At 1121 UTC, the tower controller had visual contact to the aircraft and issued landing clearance, the pilot read back the clearance and requested to reduce the approach light intensity. The tower controller reduced the light intensity and confirmed whether the intensity was appropriate then the pilot affirmed. At 1124 UTC, the aircraft touched down and bounced. After the third bounce, the pilot attempted to go around and the aircraft touched the runway. The tower controller noticed that the red light on the right wing was lower than the green light on the left wing. The aircraft moved to the right from the runway centerline and stopped near taxiway D. The tower controller realized that the aircraft was not in normal condition and pressed the crass bell then informed the Airport Rescue and Fire Fighting (ARFF) personnel by phone that there was aircraft accident near the taxiway D. At 1126 UTC, the pilot advised the tower controller that the aircraft stopped on the runway and requested assistance. The tower controller acknowledged the message and advised the pilot to wait for the assistance. While waiting the assistance, the pilot kept the engines run to provide lighting in the cabin. At 1129 UTC, the tower controller advised the pilot to shut down the engines since the ARFF personnel had arrived near the aircraft to assist the evacuation. Passenger evacuation completed at approximately 10 minutes after the aircraft stopped.

At 2323 UTC, the pilot made initial contact with Ilaga Aerodrome Flight Information Services (AFIS) officer and reported that the aircraft position was at Ilaga Pass and informed the estimate time of arrival Ilaga would be on 2327 UTC. Ilaga Aerodrome Flight Information Services (AFIS) officer advised to continue descend to circuit altitude and to report when position on downwind. At 2330 UTC, the AFIS officer called the pilot and was not replied. The AFIS officer asked pilot of another aircraft in the vicinity to contact the pilot of the DHC-4 Caribou aircraft and did not reply. At 0020 UTC, Sentani Aeronautical Information Service (AIS) officer declared the aircraft status as ALERFA. At 0022 UTC, Timika Tower controller received information from a pilot of an aircraft that Emergency Locator Transmitter (ELT) signal was detected approximately at 40 – 45 Nm with radial 060° from TMK VOR (Very High Frequency Omni Range) or approximately at coordinate 4°7’46” S; 137°38’11” E. This position was between Ilaga Pass and Jila Pass. At 0053 UTC, the aircraft declared as DETRESFA. On 1 November 2016, the aircraft wreckage was found on a ridge of mountain between Ilaga Pass and Jila Pass at coordinate 4°5’55.10” S; 137°38’47.60” E with altitude approximately of 13,000 feet. All occupants were fatally injured and the aircraft destroyed by impact force.

The crew was performing an ambulance flight from Yogyakarta-Adisujipto Airport to Jakarta-Halim Perdanakusuma Airport on behalf of the Indonesian Red Cross (Palang Merah Indonesia), carrying one patient, two doctors, two accompanists and three crew members. The approach was completed by night and marginal weather conditions. After touchdown on runway 24, the aircraft skidded on a wet runway. After a course of 1,300 metres, it veered to the right and departed the runway surface. While contacting soft ground, the right main gear was torn off while the left main gear partially collapsed. Then the aircraft bounced and impacted the ground several times, causing the left wing to be bent. Eventually, the right engine partially detached from the pylon. All eight occupants were rescued and the aircraft was damaged beyond repair. There was no fire.

On 13 September 2016, a Boeing 737-300 Freighter, registered PK-YSY was being operated by PT. Trigana Air Service on a scheduled cargo flight from Sentani Airport, Jayapura (WAJJ) to Wamena Airport, Wamena (WAVV), Papua, Indonesia. Approximately 2130 UTC, during the flight preparation, the pilot received weather information which stated that on the right base runway 15 of Wamena Airport, on the area of Mount Pikei, low cloud was observed with the cloud base was increasing from 200 to 1000 feet and the visibility was 3 km. At 2145 UTC, the aircraft departed Sentani Airport with flight number IL 7321 and cruised at altitude 18,000 feet. On board the aircraft was two pilots and one Flight Operation Officer (FOO) acted as loadmaster. The aircraft carried 14,913 kg of cargo. The Pilot in Command (PIC) acted as Pilot Flying (PF) while the Second in Command (SIC) acted as Pilot Monitoring (PM). There was no reported or recorded aircraft system abnormality during the flight until the time of occurrence. After passing point MALIO, the aircraft started to descend. The pilot observed the weather met the criteria of Visual Meteorological Condition (VMC). The pilots able to identify another Trigana flight from Sentani to Wamena in front of them. While passing altitude 13,500 feet, approximately over PASS VALLEY, the Wamena Tower controller instructed the pilot to report position over JIWIKA. When the aircraft position was over point JIWIKA, the Wamena Tower controller informed to the pilot that the flight was on sequence number three for landing and instructed the pilot to make orbit over point X, which located at 8 Nm from runway 15. The pilot made two orbits over Point X to make adequate separation with the aircraft ahead prior to received approach clearance. About 7,000 feet (about 2,000 feet above airport elevation), the pilot could not identify visual checkpoint mount PIKEI and attempted to identify a church which was a check point of right base runway 15. The pilot felt that the aircraft position was on right side of runway centerline. About 6,200 feet (about 1,000 feet above airport elevation), the PF reduced the rate of descend and continued the approach. The PM informed to the PF that runway was not in sight and advised to go around. The PF was confident that the aircraft could be landed safely as the aircraft ahead had landed. Approximately 5,600 feet altitude (about 500 feet above airport elevation) and about 2 Nm from runway threshold the PF was able to see the runway and increased the rate of descend. The pilot noticed that the Enhanced Ground Proximity Warning System (EGPWS) aural warning “SINK RATE” active and the PF reduced the rate of descend. While the aircraft passing threshold, the pilot felt the aircraft sunk and touched down at approximately 125 meters from the beginning runway 15. The Flight Data Recorder recorded the vertical acceleration was 3.25 g on touchdown at 2230 UTC. Both of main landings gear collapsed. The left main landing gear detached and found on runway. The engine and lower fuselage contacted to the runway surface. The aircraft veer to the right and stopped approximately 1,890 meters from the beginning of the runway 15. No one was injured on this occurrence and the aircraft had substantially damage. Both pilots and the load master evacuated the aircraft via the forward left main cargo door used a rope.

The single engine airplane departed Wamena Airport at 0739LT on a cargo flight to Lolat, carrying two passengers, one pilot and a load of building materials for a total weight of 1,190 kilos. On short final to Lolat Airfield, the aircraft impacted the roof of a wooded house and crashed, bursting into flames. All three occupants of the airplane evacuated safely while three people in the house were injured. The aircraft was totally destroyed by a post crash fire.
