The aircraft sustained damage to a leading edge slat on the right-hand wing. EI-EGD was turning onto the stand across the back-of-stand road the vehicle was travelling on. Conclusion A Bulmor SideBull OMNI 135 vehicle collided with EI-EGD because the vehicle driver did not see the aircraft or did not anticipate it would turn onto stand.

The stand and road layout in the area created the potential for conflict between vehicles and aircraft to arise from any direction.
