What happened
A Saudi Aerospace SA2DO27 had landed and was proceeding northbound on the taxiway toward the gate. During this taxi phase, the aircraft's taxi, landing, recognition, and strobe lights were turned off.
As the aircraft moved toward its destination, an eastbound fuel tanker truck approached the intersection of the taxiway and the vehicle service road. The driver of the tanker truck failed to stop at a posted 'STOP FOR ACFT' sign. This failure resulted in the tanker truck colliding with the aircraft, which partially severed the left wing.
Findings
The driver of the fuel tanker truck stated that the aircraft was not visible until it was directly in front of the vehicle, at which point stopping was no longer possible. An examination of the driver's visibility revealed that the view between the 1:30 and 2:00 positions was partially obstructed by the structure of the truck. Furthermore, the view between the 2:00 and 3:00 positions was considerably restricted by the truck's cage structure and the equipment stored within it.
Airport regulations specify that 'low silhouette' aircraft are required to taxi with landing lights illuminated until they have cleared all taxiways and intersecting vehicle access roads.
