​As the iSTARS Secure Portal contains classified accident and audit data, access is currently limited to representatives of:


      • State Civil Aviation Authorities,
      • ICAO Regional Offices,
      • Intergovernmental organisations,
      • Regional State Safety Oversight Organisations, and
      • Accident Investigation Boards.

If you are not part of any of these organisations, your request will be rejected. If you are not eligible, please contact your local civil aviation authority for further information or data requests.


iSTARS is a group on the ICAO Secure Portal (https://portal.icao.int). If you are already member of another group on the ICAO Secure Portal, this means that you already have an account. According to the terms of use of the ICAO Secure Portal, only one account is allowed per user, with all the groups this user needs to access combined at the same account.

In this case, in order to request access to iSTARS, you need to login to the ICAO Secure Portal by using your account and use then the Group Membership link to subscribe to the iSTARS group. Follow the lost username/password link to revocer your credentials if you have lost them. For any other assistance, please contact the ICAO Secure Portal administrator (ICAOPortalAdmin@icao.int).
