The Freedom of Information Act 2000 (FOIA) provides a right of access to all types of recorded information held by public authorities. It doesn’t provide access to information about the environment, or about you as an individual, which are covered by the Environmental Information Regulations 2004 and the General Data Protection regulation (GDPR) respectively.

In compliance with the rights of public access to information under the Freedom of Information Act 2000 (FOIA), and as a subsidiary of the Civil Aviation Authority, Air Safety Support International (ASSI) has adopted the Model Publication Scheme set down by the Information Commissioner’s Office.

Identifying the information you require

Before making a request under the Freedom of Information Act or the Environmental Information Regulations (EIR) please check if the information you require is already available by searching the other pages on this website using the Search facility.

Please make your request as specific as possible.  If we do not fully understand your request, we will contact you and confirm what it is you require. We will acknowledge receipt of your Request.

Please note that air accident investigation is the responsibility of the Department for Transport.


ASSI will endeavour to provide the information requested within 20 working days of the Request being received. If the information requires a substantial amount of collation, or is very large, or requires additional research we will contact you, usually by telephone, and let you know that we will require more than 20 working days to assemble the results. This will not exceed 40 working days. The revised date will be confirmed to you in writing or by email.

In some circumstances, another public body may hold the information. If we think another public body may hold some, or all, of the information, we will advise you to request it from them.

Providing the Information

If it is substantial, we will suggest you visit the offices of ASSI in Crawley, where there are facilities for viewing and copying.

Data Protection

If you are making a request for access to personal information about you, this will be treated as a subject access request under the GDPR.  If you are making a request for access to personal information about another person (third party data) there are a number of exemptions to disclosure. We will contact you if necessary, discuss your request and determine if it can be lawfully met.


Certain classes of information are exempt from disclosure. Should any or all of the information you have requested be considered exempt, we will tell you which exemption(s) have been applied.  You have the right to challenge the exemption(s) and, should you remain dissatisfied, you can appeal to the Information Commissioner.


There is no charge made for providing information.  However, if the total work involved in finding, sorting, editing and redacting material exceeds 18 hours then ASSI is not obliged to provide the information.
