s 90 Effect of statutory lien
90.—(1) Sections 89 to 94 have effect in relation to an aircraft while a statutory lien on the aircraft continues in effect. (2) Those provisions apply —(a) despite any encumbrance in respect of the aircraft, and any sale or disposition of, or dealing in, the aircraft or an interest in the aircraft; and (b) whether or not the Authority has possession of the aircraft at any time. (3) For the purposes of priorities among creditors and the purposes of the distribution of the proceeds of a sale made under section 93, the statutory lien has effect as a security interest in respect of the aircraft ranking in priority —(a) after any security interest (other than a floating charge) in respect of the aircraft created before the time of registration of the statutory lien, to the extent that the security interest covers a debt incurred before that time; and (b) before any security interest that is not covered by paragraph (a), or to the extent that it is not covered by paragraph (a). (4) A statutory lien ceases to have effect in the following cases, and not otherwise:(a) when there is no longer any outstanding amount covered by the statutory lien; (b) when the aircraft is sold or disposed of under section 93; (c) when an authorised employee directs in writing that the statutory lien ceases to have effect. (5) When a statutory lien ceases to have effect, the authorised employee must make an entry in the Register of Statutory Liens as prescribed by the regulations. (6) A statutory lien is not to be taken by implication to have any effect otherwise than as provided by this Act.
