• A minor modification to a UK registered CAA regulated non-EASA aircraft is one that has no appreciable effect on airworthiness, but still requires CAA approval.

    CAP 1419 'Guidance to applicants when preparing applications for the approval of minor modifications to non-EASA aircraft' outlines how to achieve a minor modification approval.

    It also covers an alternative process to enable the use of CS-STAN for 'standard' changes (modifications) and repairs, and includes CAA Form 123 as the Standard Change/Standard Repair (SC/SR) embodiment record for an aircraft.

    EASA is responsible for providing equivalent guidance (CS-STAN) for the approval of standard changes and standard repairs to EASA aircraft.
