Reporting procedures

LVNL is required by law to report serious incidents to the Dutch Safety Board (DSB).

The DSB conducts independent investigations into the causes and consequences of disasters, serious accidents and other major incidents, not just in the aviation sector but also in other fields. These exercises highlight lessons to be learnt and result in recommendations to improve safety. Their aim is to learn from such events, not to place blame. When required to do so, it is the LVNL supervisor who notifies the DSB of an incident. The following events must be reported.

Emergency situations (“Mayday” calls).

Collisions and near-collisions (loss of separation) between aircraft.

Collisions and near-collisions between aircraft and obstacles on the ground.

Take-offs or attempted take-offs from an out-of-use or occupied runway, or from one not authorised for take-off by air traffic control.

Landings or attempted landings on an out-of-use or occupied runway, or from one not authorised for landing by air traffic control.

Runway excursions during take-off or landing.

Runway incursions with actual or potential risk of collision.

The DSB decides whether or not to begin an investigation within five days of receiving notification from LVNL.

Under the statutory Civil Aviation Incident Notification Order (Besluit melding voorvallen in de burgerluchtvaart), both LVNL as an organisation and its air traffic controllers as individuals are also required to report incidents related to the provision of air traffic control services to the Aviation Incidents Analysis Bureau (Analysebureau Luchtvaartvoorvallen) at the Human Environment and Transport Inspectorate (Inspectie voor Leefomgeving en Transport, ILT). Again, the aim is to draw lessons from these events.
