Srilankan Airlines flight UL707, an Airbus A320-214, drifted to right side of the runway during landing at Seychelles International Airport.
Probable cause:
Before touchdown, a commanded right roll angle maintained for ~21s led to a deviation of the aircraft toward the right of the runway centerline.
The pitch-up order applied by the flight crew at ~110ft RA led the aircraft to float above the runway at ~50ft RA and thus exposed the aircraft to the lateral wind. The left crosswind component contributed to increase the deviation of the aircraft to the right of the runway centerline.
On ground, in spite of a leftward rudder pedal application, the aircraft skidded toward the right of the runway. This tendency to skid was a consequence of the aircraft dynamics (right roll + crosswind) and the reported weather conditions that led to a wet runway.
Additional contributors which may have perturbed approach and landing were:
- After a go-around, second approach was performed during the night with gusty wind conditions.
- Runway was most probably wet, as “rainy conditions” was reported in incident statement of the PIC and confirmed by METAR (heavy rain showers).
