Notification

A so-called runway incursion took place at Maastricht Aachen Airport on Monday 26 June 2017. This situation arose because a vehicle entered the runway without permission. LVNL is investigating this incident and has reported the occurrence to the Dutch Safety Board.

Runway incursion

The term 'runway incursion' refers to any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle or person on the protected area of a surface designated for the landing and take-off of aircraft.

Occurrence investigation

LVNL’s primary safety task is to maintain the separation of aircraft in the air, and between vehicles and other obstacles when on the ground. Air traffic controllers internally report any safety related occurrence, with the objective to learn lessons from those occurrences,  thereby reducing the chance that similar occurrences will take place again in the future. All reported occurrences are investigated by LVNL, as part of LVNL’s ongoing commitment to improve safety.

Description of the situation

In the morning of Monday 26 June, the airport requested permission to allow a vehicle to cross the runway. This was refused by the air traffic controller because of a planned take-off of an aircraft, type Diamond Star DA40, a light twin-engine aircraft.

Shortly afterwards, the airport requested permission to allow persons to cross the taxiway. The air traffic controller gave permission for this. The air traffic controller then gave take-off clearance to the Diamond Star.

The air traffic controller saw that the vehicle to which no permission had been granted started to drive in the direction of the runway and immediately withdrew the Diamond Star’s take-off clearance. The aircraft crew then aborted the take-off.

The vehicle soon left the runway and the Diamond Star was given new take-off clearance.
