Western (Fly)

The airplane was on a VFR charter flight from Kiunga Airport, Western Province to Tekin Airstrip, Sandaun Province, Papua New Guinea. During the landing roll aircraft sustained a left main landing gear assembly collapse and subsequent runway excursion. There were seven persons onboard: one pilot and six passengers. At 09:06, P2-BWC departed Kiunga Airport and arrived at Tekin circuit area at 09:40. The pilot established the aircraft on the final approach profile, he configured the aircraft for landing by fully extending the flaps and maintained an airspeed of about 80 knots (kts). The pilot also stated that he experienced a downdraft prior to touch down. The aircraft landed at 09:43 with an airspeed of 75 knots as recalled by the pilot. The aircraft touched down about 3m short of the airstrip edge boundary. The investigation determined that due to reduced damping effect of the oleo and/or the tyre of the left main landing gear, the landing gear attachment bolts sustained significant impact stress from the landing impact force and snapped, causing the gear assembly to collapse and separate from the aircraft. Subsequently, the left wing abruptly dropped, and the aircraft began veering to the left, towards the eastern edge of the airstrip. The aircraft continued veering to the left and subsequently the left wingtip struck the outer edge of the extended right-hand flap of P2-BWE, a wreckage of the same aircraft type owned and operated by NASL that was involved in a similar accident on 18 January 2022, causing P2-BWC to abruptly veer further left and skid across the airstrip boundary as the nose-wheel and right main wheel bogged into the ground. The pilot immediately shut down the engine and evacuated the passengers with the assistance of one of the Operator’s personnel who was also a passenger on board. There were no reported injuries and the aircraft sustained significant damage.

The airplane was conducting a single pilot VFR charter flight from Kiunga Airport, Western Province to Tekin Airstrip, Sandaun Province, Papua New Guinea when during the landing roll, the aircraft sustained a left Main Landing Gear (MLG) assembly collapse and subsequent runway excursion. There were eight persons onboard: one pilot and seven passengers. At 08:43, P2-BWE departed Kiunga Airport and arrived at Tekin Airstrip circuit at 09:18. The pilot then tracked towards the Northwest of the airstrip and made a left base turn for approach. The pilot stated that he established the aircraft on final approach with an airspeed of 120 kts. He subsequently configured the aircraft for landing; propeller pitch set to full fine, power set to maintain nominated approach speed, and full flap. The pilot indicated that he reduced airspeed while on approach and maintained an airspeed between 85 and 90 kts. As he flared the aircraft to land, the airspeed was between 75 to 80 kts. The touchdown speed, as he recalled, was 75 kts. The aircraft touched down two metres short of the designated landing threshold of runway18, which had an elevation of 15cm. Reviewing the flight records of the pilot, and from his interview, the AIC deduced that the pilot was not adequately familiar with Tekin Airstrip. The aircraft sustained substantial damaged. All the passengers and pilot evacuated the aircraft without injuries.

On the afternoon of 13 April 2016, a Pilatus Britten Norman Turbine Islander (BN-2T) aircraft, registered P2-SBC, operated by Sunbird Aviation Ltd, departed from Tekin, West Sepik Province for Kiunga, Western Province, as a charter flight under the visual flight rules. On board were the pilot-in-command (PIC) and 11 passengers (eight adults and three children). The aircraft was also carrying vegetables. The pilot reported departing Oksapmin at 13:56. The pilot had flight planned, Kiunga to Oksapmin to Kiunga. However, the evidence revealed that without advising Air Traffic Services, the pilot flew from Oksapmin to Tekin. On departure from Tekin the pilot transmitted departure details to ATS, stating departure from Oksapmin. The recorded High Frequency radio transmissions were significantly affected by static and hash. The weather at Kiunga was reported to be fine. As the aircraft entered the Kiunga circuit area, the pilot cancelled SARWATCH with Air Traffic Services (ATS). The pilot did not report an emergency to indicate a safety concern. Witnesses reported that during its final approach, the aircraft suddenly pitched up almost to the vertical, the right wing dropped, and the aircraft rolled inverted and rapidly “fell to the ground”. It impacted the terrain about 1,200 metres west of the threshold of runway 07. The impact was vertical, with almost no forward motion. The aircraft was destroyed, and all occupants were fatally injured.

A Pacific Aerospace PAC P-750 XTOL single engine aircraft was chartered to transport store goods and six passengers from Kiunga to Golgubip. Although Golgubip is in mountainous terrain and the weather in the area is often poor, the pilot was tasked to fly there without ever having been to Golgubip before. The terrain to the north north east of Golgubip rises gradually behind the airstrip. Visual illusions which may affect the pilot’s perception of height and distance can be associated with airstrips situated in terrain of this kind. On arrival at Golgubip, the pilot orbited and positioned the aircraft for landing. During the final approach he decided to discontinue the approach and to initiate a go-around procedure. The aircraft impacted terrain approximately 500 metres northwest of the airstrip and was substantially damaged. The six passengers were unhurt while the pilot sustained serious injuries. The pilot was treated in Golgubip following the accident, and was airlifted the next day to Tabubil, where he was admitted to hospital. It was later reported that the GPWS alarm sounded on approach until the final impact.

During the takeoff roll from a grassy runway (780 metres long), the pilot noted standing water on the ground. He attempted to take off prematurely to avoid these puddles but the aircraft stalled and crash landed. All three occupants escaped uninjured while the aircraft was damaged beyond repair.

While descending to Tabubil Airport on a cargo flight from Port Moresby, the crew encountered poor weather conditions and decided to divert to Kiunga. While approaching Kiunga, the right engine failed, followed shortly later by the left engine. The aircraft lost height, struck trees and crashed 5 km from the airport. One pilot survived while both other occupants were killed. The aircraft was leased to the Vanimo Trading Company.

The twin engine aircraft departed Tabubil and a regular schedule flight to Selbang, carrying 26 passengers and two pilots. After passing over Olsobip, the crew encountered poor visibility due to clouds. While flying at an altitude of 6,400 feet in clouds, the aircraft struck the slope of a mountain located about 9 km south of Selbang. The aircraft was destroyed and all 28 occupants were killed. At the time of the accident, the cloud layer was reported from 4,000 to 10,000 feet.

While cruising in poor weather conditions, the twin engine aircraft struck the slope of a mountain located 54 km southeast of Tabubil. The wreckage was found few hours later and all seven occupants were killed.

On short final to Golgubip Airstrip, the twin engine airplane banked left, causing the left wing to struck the ground and the aircraft crashed 100 metres short of runway threshold. The pilot and a passenger were seriously injured while nine other occupants were killed.

The crew departed Kiunga on a cargo flight to a remote area of the Western Province. En route, weather conditions deteriorated when the aircraft crashed in unknown circumstances in the region of the Fly River. Both pilots were killed.
