(source: header)\n- It applies to DH114 (Heron) series aeroplanes. The specific entry shown is AD/DH114/44 and the entry records that AD/DH114/44 has been superseded by AD/DH114/35B. (source: \"DH114 (Heron) Series Aeroplanes\" and \"AD/DH114/44 Superseded by AD/DH114/35B\")\n\nWho this affects\n\n- Aircraft owners, operators, maintainers and any person responsible for the airworthiness of DH114 (Heron) series aeroplanes listed in the Schedule. They are the parties required to observe and comply with the applicable airworthiness directive named in the Schedule. (source: header and AD entry)\n\nHow it works mechanically\n\n- The Schedule records regulatory airworthiness directives (ADs) issued under the Civil Aviation Regulations. An AD named in the Schedule imposes a compliance obligation; when one AD is marked as \"superseded by\" another AD, the earlier AD no longer represents the current directive for that aircraft type and the later AD is the operative requirement. In this entry AD/DH114/44 is replaced by AD/DH114/35B, so compliance obligations move from AD/DH114/44 to AD/DH114/35B. (source: header and AD entry)\n\nOfficial rationale and what the record does not show\n\n- The excerpt does not state the technical reason for the supersession, the specific inspection/repair/modification requirements, nor the compliance deadlines. The Schedule entry itself only records the administrative fact of supersession. Any claimed safety rationale or technical details would need to be read in the text of AD/DH114/35B. (source: the AD line as presented)\n\nCosts, incentives, and who decides\n\n- Who pays: aircraft owners/operators and maintainers bear the direct costs of meeting the operative AD (inspections, maintenance, parts, labour). (source: the nature of ADs recorded in the Schedule)\n- Who decides: the Civil Aviation Safety Authority (CASA), operating under the Civil Aviation Regulations, issues and updates ADs and records them in the Schedule. The Schedule entry here reflects CASA’s administrative action. (source: header)\n- Behavioural effect: affected parties must stop treating AD/DH114/44 as the active directive and must consult and comply with AD/DH114/35B instead; this changes what maintenance/inspection actions and records are required. (source: the AD entry)\n\nImplementation and compliance risks\n\n- Administrative risk: operators need to track supersessions and ensure maintenance and records reflect the currently operative AD. (source: the supersession notation in the Schedule)\n- Information risk: because this entry does not include the substantive requirements of AD/DH114/35B, affected parties must obtain the full text of AD/DH114/35B to determine precise actions, deadlines and costs. (source: the absence of substantive detail in the entry)\n\nTrade-offs and opportunity costs highlighted by the entry\n\n- The Schedule entry transfers compliance obligations from one named AD to another without showing the substantive content; that creates a simple administrative burden (find and follow the new AD). Any differences in required work between AD/DH114/44 and AD/DH114/35B—such as additional inspections or modifications—will create real costs or time trade-offs for operators, but those substantive effects are not visible in this excerpt.
