This application is only to be used by organisations approved by the CAA and to submit ARC validity information for UK-registered aircraft. Any other use is prohibited.

This online facility can be used to submit ARC data to the CAA. It does not allow the retrieval or correction of previously entered data.

If previously submitted information is incorrect or you are having difficulties with this system, please contact a member of the customer service team as soon as possible on +44 (0) 1293 768374 between the hours of 08:30 and 16:00 Monday to Friday.


As a consequence of EASA Regulation changes the ARC Online system has been updated to reflect changes to the ARC 15A and 15B formats. The new format requires that the total aircraft hours flown at the issue, or extension, of the ARC are shown on the ARC. Consequently, entering data in the hours flown field in ARC Online will be mandatory for all aircraft, with the exception of balloons and airships.
