Guidance for what an approved scheme should address is referenced in Airworthiness Advisory Circular No. 62 dated March 1972 (Note).\n- Compliance depends on timely approval of schemes and availability of installers (Requirement; Compliance).\n\nWho pays, who decides, and what behaviour changes\n\n- Who pays: owners/operators are responsible for arranging and funding the modification (Requirement).\n- Who decides: the Secretary approves the modification schemes that installations must follow (Requirement).\n- Behaviour change required: owners/operators must have front seat restraints altered to safety-harness installations that conform to an approved scheme and complete the work before the specified deadline (Requirement; Compliance).\n\nPractical trade-offs, compliance burden and observable effects (source-grounded)\n\n- Compliance burden: the instrument creates a one-time retrofit obligation for every affected front seat restraint, which will require coordination with installers and purchase of harness assemblies as specified by an approved scheme (Requirement; Note).\n- Administrative discretion: technical approval and acceptance of particular installation schemes are exercised by the Secretary rather than being fully specified in the directive text (Requirement; Note).\n- Timing constraint: the instrument sets a fixed compliance date, so completion depends on schemes being approved and installations being performed ahead of that date (Compliance).\n\nSource citations\n\n- Requirement: \"Modify each front seat restraint installation by fitting a safety harness in accordance with a scheme approved by the Secretary.\"\n- Note: \"Guidelines for installation schemes are outlined in airworthiness Advisory Circular No. 62 dated March 1972.\"\n- Compliance: \"Before 1 January 1974.\""},"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This is a discrete, single-issue safety directive from 1972.
