Who can I contact with questions about safety?

You have a question about safety of aircraft or you experience something in which an aircraft in the air or on the ground is involved, and you wonder if this is actually safe. You can then send an email to the Human Environment and Transport Inspectorate (ILT) of the Ministry of Infrastructure and the Environment via the  ILT contact form. The ILT employees will answer your question or report, and/or will arrange for an investigation to be conducted.
