(See subregulation 39.001(1).)\n\nWhich ADs are affected\n\n- The Schedule lists four ADs for the FN-333 series: AD/FN-333/1 (Fuel Solenoid Valve Relocation - Flexible Hose Installation) [cancelled], AD/FN-333/2 (Inlet Manifold Rear Drain - Modification), AD/FN-333/3 (Front Seat Restraint Installations - Modification) and AD/FN-333/4 (Electric Fuel Pump Operation - Placard). (See Schedule 1.)\n\nWhat changes for owners, operators and maintainers\n\n- Mechanically, the instrument revokes the listed ADs and re-makes each of them as separate instruments. The instrument includes a note saying each re-made AD is in exactly the same form as the latest published edition of that Directive. That implies no substantive change to the technical requirements or compliance obligations in those ADs. (See the Note following the instrument.)\n\nWho decides and who pays\n\n- The decision to revoke and re-make the ADs is taken by the CASA delegate under subregulation 39.001(1). (See the opening paragraph.)\n- The affected parties who carry the compliance burden are owners, operators and maintainers of the SIAI Marchetti FN-333 (Riviera) series aeroplanes: they remain subject to the same AD requirements after re-issuance if the note is followed. Any direct costs of compliance therefore remain with those parties; the instrument itself does not introduce new compliance duties. (See Schedule 1 and the Note.)\n\nIncentives, costs and administrative effects\n\n- Because the ADs are re-made in the same form as the latest published editions (the instrument states this explicitly), the operational incentives for aircraft operators — what they must do to comply — are not changed by this instrument. (See the Note.)\n- The main effects are administrative: CASA revokes the old instruments and issues new standalone instruments. That imposes an administrative cost on CASA to perform the revocation/re-issuance and may impose minor administrative tasks on operators (for example, replacing instrument references in records), but the technical compliance burden remains the same. (See the opening paragraph and Schedule 1.)\n\nDiscretion and implementation risk\n\n- The power to revoke and re-make is exercised by the delegate under subregulation 39.001(1), so the instrument reflects an exercise of delegated regulatory power. (See subregulation 39.001(1).)\n- Because the instrument states the content of each re-made AD matches the latest published edition, the risk of substantive regulatory change or new technical requirements from this action is low; the main implementation risk is limited to administrative updating and publication accuracy.
