The approach to runway 27 at Arjeplog Airport was initiated with a visual descent, but unfortunately, the aircraft failed to maintain a stable and controlled glide path. The approach quality was subpar, with a significant deviation from the ideal glide slope. As a result, the aircraft touched down 14 miles south of the runway threshold, well short of the intended landing site.
The touchdown speed of 319 kt was significantly higher than the recommended threshold speed, indicating a loss of control during the final stages of the approach. The heavy touchdown rate of -31,595 fpm further exacerbated the situation, resulting in a hard and potentially damaging landing. The aircraft's inability to maintain a stable approach and control the descent ultimately led to the premature touchdown.
The rollout phase was marked by a lack of centreline alignment, with the aircraft deviating significantly from the runway centreline. The local weather conditions, with a temperature of 15 °C and a light wind of 2 kt at 262°, did not pose a significant challenge to the landing. However, the pilot's failure to execute a controlled approach and touchdown resulted in a score of 55.5%.
