(Source lines: header and AD title.)\n\n- The short operative statement in the text is: \"This AD contents has been removed from the listing because the aircraft model is not currently on the register.\" That means the AD is no longer shown in the listing because there are no BAe 125 series aeroplanes recorded on the Australian register at the time the entry was updated. (Source line: removal statement.)\n\nWho it affects and who decides\n\n- The AD was directed at operators or owners of British Aerospace BAe 125 series aeroplanes (the subject named in the entry). The decision to include or remove the AD from the Schedule is recorded by the Civil Aviation Safety Authority under the Commonwealth Civil Aviation Regulations framework. (Source lines: AD title and header.)\n\nWhat changed mechanically and why that matters\n\n- Mechanically, the requirement that had been recorded under AD/HS 125/31 (an inspection requirement for passenger seats, by the AD title) has been removed from the public listing because the specified aircraft model is not on the Australian register. That removal means the listing no longer imposes any active, listed inspection obligation on operators in Australia for that AD while no BAe 125s are registered. (Source line: removal statement.)\n\nCosts, incentives, trade-offs and implementation points to note\n\n- Who pays: when an AD is active, inspection costs and any corrective work are normally borne by the aircraft owner/operator named by the AD. Because this entry has been removed from the listing for the stated administrative reason, there is no active listed inspection obligation under this AD for currently-registered Australian operators, so those particular compliance costs are not currently imposed by this listing. (Inferred from the fact that the AD applied to the BAe 125 series named in the entry and the removal statement.)\n\n- Who decides and discretion: the Civil Aviation Safety Authority administers the Schedule of Airworthiness Directives and has discretion to list or remove ADs from the published Schedule; the document records that removal decision in this instance. (Source: header and removal statement.)\n\n- Incentives and trade-offs: removing the AD from the listing reduces immediate regulatory compliance obligations for Australian-registered operators if no affected aircraft are on the register, and reduces the regulator's active oversight load for that entry. The trade-off implicit in that administrative change is that no listed inspection action remains for that AD in Australia while the model is unregistered. (Inferred from the removal statement.)\n\n- Compliance burden and implementation risk: the text does not set out any transitional rules or exceptions; it simply records removal from the listing because of register status. That creates low complexity for administrators and operators while the model is unregistered, but could require administrative action to relist or reissue an AD should the model return to the register. (Source: removal statement; administrative implication noted.)\n\n- Effects on private choice and markets: the immediate effect is limited and narrowly targeted: operators of BAe 125s on the Australian register would have carried the inspection cost when the AD was active; because no such registered aircraft exist (per the statement), the active burden is removed. The entry does not change broader competition, ownership rules, or aircraft operation rules beyond the specific AD listing. (Source: AD title and removal statement.)\n\nBottom line\n\n- The entry documents that AD/HS 125/31 (Passenger Seats - Inspection for BAe 125 series aeroplanes) has been removed from the Schedule because the aircraft model is not on the Australian register. That removal means the Schedule no longer lists an active inspection requirement under that AD for Australian-registered aircraft while the model remains unregistered.
