Flight PC121 Crash in Fiji (DQ-AFN)

Accident Overview and Flight Details On the morning of the incident, a twin-engine aircraft departed Suva-Nausori Airport at 0525 local time on a scheduled service to Nadi, designated flight PC121. The aircraft was carrying 15 passengers and two pilots. The crew initiated a climb via route 28 Golf under relatively good weather conditions. At 0532 local time, the pilot reported an altitude of 5,500 feet, located 22.4 kilometers from the airport. One minute later, the pilot reported reaching 6,000 feet, after which the aircraft disappeared from radar screens eight minutes after takeoff. ## Wreckage Location and Casualties The wreckage was discovered at an altitude of 540 meters in a wooded, mountainous area within the Mataicicia Mountain Range. The site was situated 35.2 kilometers west of Nausori Airport and south of the village of Nasirotu. The aircraft was completely destroyed by impact forces, resulting in the deaths of all 17 occupants. The fatalities included nine Fijians, five Australians, one New Zealander, one Chinese national, and one Japanese national. ## Official Findings and Probable Cause The official investigation determined that weather, aside from reduced visibility in cloud, did not play a part in the accident. The combination of a dark night, cloud, and limited ground lights provided the crew with few external visual cues, requiring constant scanning of flight instruments to maintain the desired aircraft performance and flight profile. This demanding task may have led to crew disorientation and loss of control with insufficient altitude to recover. The evidence was consistent with the aircraft colliding with one or more objects before breaking up and impacting the ridge, though the exact sequence of the in-flight break-up could not be determined. ## Key Investigation Findings The investigation identified several critical factors: the wreckage was found 3 kilometers south of the intended route; the aircraft struck a tall tree with its right wing at 390 meters above ground, flew for another 1,300 meters, and then crashed; the minimum safe altitude for the area was 5,400 feet; and no technical anomalies were found on the aircraft. Investigators were unable to determine the exact cause of the crew's failure to comply with the minimum safe altitude. Additionally, the captain had insufficient rest time prior to the flight and consumed an above-therapeutic level of antihistamine, which may have affected his capabilities. The operator's published standard operating procedures for the Embraer Bandeirante aircraft were found to be inadequate. Weather conditions were considered good, with 40 kilometers of visibility, scattered clouds at 2,200 feet, and no wind. The total weight of the aircraft was just below the maximum takeoff weight.
