Circumstances:
On 15 September 2021, a DHC-6-300 (Twin Otter) aircraft registered PK-OTW was being operated for an unscheduled cargo flight from Douw Aturure Airport (WABI), Nabire, Papua to Bilorai Airport (WAYB), Intan Jaya, Papua. The aircraft was operated by two pilots accompanied by one engineer on board. The filed flight plan for the flight indicated that the aircraft would be operated under Visual Flight Rule (VFR) with fuel endurance of 2 hours 30 minutes. The estimate time departure for the flight was at 0640 LT. At 0610 LT, the pilot received weather observation report from the Bilorai aeronautical communication officer (ACO) that the visibility was 5 up to 7 kilometers, several clouds over the airport and all final areas were clear. About 7 minutes later, the ACO updated the observation report which indicated that the visibility changed to 7 up to 8 kilometers (km). After the cargo loading process and the flight preparation had completed, the aircraft taxied to Runway 16. At 0644 LT, the aircraft departed and climbed to the cruising altitude of 9,500 feet. Prior to the departure, there was no record or report of aircraft system malfunction. The Pilot in Command (PIC) acted as Pilot Monitoring (PM) while the Second in Command (SIC) acted as Pilot Flying (PF). At 0658 LT, the PK-OTW pilot reported to the Nabire air traffic control that the aircraft was at 25 Nm with altitude of 9,500 feet. At 0702 LT, the SIC asked the PIC to have the aircraft control as PF. During flight, the PK-OTW pilots monitored weather information provided by the pilots of two other aircraft that flew ahead of the PK-OTW to Bilorai. Both pilots monitored that the first aircraft (Cessna 208B EX) landed using Runway 27 while the second aircraft (Cessna 208B) would use Runway 09. At 0715 LT, the PIC advised the SIC to use the Runway 27 for landing. At 0719 LT, the SIC made initial contact with the ACO and advised that the aircraft was approaching Bilai at altitude of 9,500 feet and the estimate time arrival at Bilorai was 0726 LT. The ACO acknowledged the pilot report and provided current weather observation as follows “…wind westerly 3 until 5 knots, final 09 open with broken fog and final 27 open, visibility 5 until 7 km, blue sky overhead”. The SIC acknowledged the weather information and advised the ACO would report when the aircraft position was on left downwind Runway 27. At 0721 LT, the SIC read the descent checklist included the item of Landing Data/Approach Briefing and was replied by completed. The Cockpit Voice Recorder (CVR) did not record any pilot’s discussion regarding to the airport minimum safe altitude since the beginning of the recording. At 0723 LT, a pilot of DHC-6-400 aircraft registered PK-OTJ, asked the PK-OTW pilot of the weather condition in Bilorai. The PK-OTJ flew behind the PK-OTW with from Nabire to Bilorai. The SIC then responded that the PK-OTW was on descend and would fly through clouds about 5 Nm to Bilorai. Thereafter, the ACO provided traffic information to PK-OTW pilot that there was an aircraft (Cessna 208B aircraft) on final Runway 09. The PIC who acted as PF acknowledged the traffic information and advised to the ACO that the PK-OTW would join left downwind Runway 27 for the landing approach. At 0725 LT, the SIC advised to the ACO that the aircraft was on left downwind Runway 27. The ACO then advised the PK-OTW pilot to report when on final Runway 27. At 07:26:12 LT, a stall warning recorded in the Cockpit Voice Recorder (CVR) then the PIC asked to the SIC to check the aircraft speed. The SIC responded the aircraft speed was 65 knots. At 07:26:16 LT, the PIC asked to the SIC to advise the ACO that they were making a go around. The SIC then advised the ACO that the PK-OTW was making a go around and was responded to report when on final. The CVR did not record pilot’s discussion about the plan maneuver of the go around. At 07:26:45 LT, the PIC informed that they were making a go around to the PK-OTJ pilot. The PK-OTJ pilot responded that the aircraft was approaching Homeyo and would reduce the speed to make enough separation with the PK-OTW. The PIC then advised the PK-OTJ that the PK-OTW would attempt to land using Runway 09. Based on the data transmitted from the flight following system, at 07:27:57 LT, the aircraft was about 3 Nm outbound from Bilorai on direction of 238°. At 07:28:22 LT, the PK-OTJ pilot advised to the ACO that the aircraft was about 6 nm to Bilai and the pilot intended to make holding maneuver over Bilai to make enough separation with the PK-OTW. At 07:28:33 LT, the SIC advised the PIC that the aircraft was at 8,200 feet and was responded that the PIC initiated turning the aircraft. A few second later, the SIC advised to the PIC that the aircraft was turning, and the aircraft was at 3.2 Nm outbound from Bilorai. At 07:28:38 LT, the last data of the flight following system recorded that the aircraft was on direction of 110°. At 07:29:25 LT, the SIC advised the PIC to fly left. Thereafter, the SIC advised the PIC that the aircraft was passing 8,000 feet. At 07:29:35 LTC, the PIC asked to the SIC about the distance to Bilorai and was responded 2.5 Nm. The SIC, reminded the PIC to fly left as the aircraft flew too close to the terrain. At 07:29:49 LT, the CVR recorded the first impact sound and the CVR recording stopped at 07:29:55 LT. At 0730 LT, the ACO asked the PK-OTW pilot intention as the aircraft was not visible from the ACO working position, and the pilot did not respond the ACO. At about the same time, the ACO heard impact sound that was predicted coming from terrain area on west of Bilorai. The ACO then called the PK-OTW pilot several times without response. Several pilots also attempted to contact the PK-OTW with the same result. The PK-OTW was found on a ridge at elevation of 8,100 feet, about 2 Nm on bearing 260° from Bilorai.

The pilot was the only person on board for this flight and the aircraft carried 694 kgs of cargo goods. At 0622 LT (2122 UTC), the pilot of PK-MEC aircraft requested clearance to the Sentani Tower controller to start aircraft engine and flying to Mamit at radial 241° with intended cruising altitude 10,000 feet. The Sentani Tower controller approved the request. At 0627 LT, on daylight condition, the aircraft took off from runway 12 of Sentani Airport, thereafter, the Sentani Tower controller advised to the pilot of PK-MEC to contact Jayapura Radar controller. At 0628LT, the pilot of PK-MEC declared “MAYDAY” on Jayapura Radar radio frequency. The Jayapura Radar controller tried to contact pilot of PK-MEC four times but no answer. At 0630 LT, the Jayapura Radar Controller requested the pilot of PK-RCE that was just took off from Sentani to visually observe the position of PK-MEC aircraft. Few minutes later, the pilot of PK-RCE reported to Jayapura Radar controller that some debris were seen on Sentani Lake and some boats were moving toward the debris location. The pilot of PK-RCE assumed that PK-MEC aircraft had crashed to the lake. The pilot fatally injured. The wreckages have been recovered including the Global Positioning System (GPS) data card.

Circumstances:
On 11 August 2018, a PAC 750XL aircraft registered PK-HVQ was being operated by PT. Marta Buana Abadi (Dimonim Air) on unscheduled passenger flight from Tanah Merah to Oksibil. At the day of the occurrence the meteorological condition at Oksibil was below the requirement of Visual Flight Rule (VFR) weather minima and did not improve. Being aware that some flights had performed flight to Tanah Merah to Oksibil and returned, the pilot decided to fly to Oksibil. At 1342 LT, on daylight condition the PK-HVQ aircraft departed from Tanah Merah to Oksibil, on board the aircraft were one pilot, one observer pilot and 7 passengers. According to the passenger and cargo manifest, the total weight of passenger and the baggage were 473 kg. Prior to the departure, there was no record or report of aircraft system malfunction. At 1411 LT, the PK-HVQ pilot made initial contact to Oksibil Tower controller and reported that the aircraft was maintaining altitude of 7,000 feet over and the estimate time arrival at Oksibil would be 0520 UTC (1420 LT). The Oksibil Tower controller advised the pilot of the latest meteorological condition that the visibility was 1 up to 2 km and most of the area were covered by cloud. At 1416 LT, the pilot reported that the aircraft position was over Oksibil Aiport and the Oksibil Tower controller instructed the pilot to continue the flight to the final runway 11 and to report when the runway had in sight. The Oksibil Tower controller and pilots of other aircraft called the pilot but no reply. On the following day, the aircraft was found on a ridge of mountain about 3.8 Nm north west of Oksibil on bearing 331° with elevation about 6,800 feet. Eight occupants were fatally injured and one occupant was seriously injured.
Probable cause:
The KNKT concluded the contributing factors as follows:
- The VFR weather minimum requirement that was not implemented properly most likely had made the pilot did not have a clear visual to the surrounding area.
- Considering that the Pilot in Command (PIC) had lack knowledge of the terrain surrounding the Oksibil area, and the absence of voice alert from the TAWS when the aircraft flying close to terrain, resulted in the PIC did not have adequate awareness to the surrounding terrain while flying into clouds and continued to fly below the terrain height until the aircraft impacted the terrain.

Circumstances:
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. The following figure showed the illustration of the aircraft track plotted on the Google earth refer to the known coordinates of Tanah Merah, Oksibil and the crash site.
Probable cause:
The possibility of the pilot being fatigue, physical and environment condition increased pilot sleepiness which might have made the pilot inadvertently falling asleep indicated by no pilot activity. The absence of GA-EGPWS aural alert and warning was unable to wake up the pilot.

Circumstances:
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.
Probable cause:
Refer to the previous aircraft that was landed safely, the pilot confidence that a safe landing could be made and disregarding several conditions required for go around.
Final Report:
