Subject to paragraphs (5) and (6), the CAA may provisionally suspend or vary any certificate, licence, approval, permission, exemption, authorisation or other document issued, granted or having effect under this Order, pending inquiry into or consideration of the case.

The CAA may, on sufficient ground being shown to its satisfaction after due inquiry, revoke, suspend or vary any such certificate, licence, approval, permission, exemption, authorisation or other document.

The holder or any person having the possession or custody of any certificate, licence, approval, permission, exemption or other document which has been revoked, suspended or varied under this Order must surrender it to the CAA within a reasonable time after being required to do so by the CAA.

The breach of any condition subject to which any certificate, licence, approval, permission, exemption or other document, other than an aerodrome licence, has been granted or issued or which has effect under this Order, in the absence of provision to the contrary in the document, renders the document invalid during the continuance of the breach.

The provisions of this article do not apply in relation to permits to which article 230 applies.

A flight manual, performance schedule or other document incorporated by reference in a certificate of airworthiness may be varied on sufficient ground being shown to the satisfaction of the CAA, whether or not after due inquiry.
