The list runs through AD/BEECH 90/1 to AD/BEECH 90/102 and includes entries marked as amendments and some entries noted as CANCELLED.\n\n**Who is affected**\n\n- Owners, operators and maintainers of Beechcraft 90 and 65‑90 (King Air) series aeroplanes: they remain bound to comply with the substantive requirements of each AD (inspections, modifications, placard installations, replacements, etc.).\n- Maintenance organisations, parts suppliers and certificated engineers who carry out AD work or supply parts required by the ADs.\n- CASA and its delegates/administration for publication, record‑keeping and enforcement of the separate AD instruments.\n\n**Why it matters (official purpose and practical effect)**\n\n- Officially this is an administrative re‑organisation: the listed ADs are revoked as a set and each is re‑issued as a separate legal instrument in the same substantive form as the latest published editions. The stated purpose is to have each AD exist as an individual instrument rather than as part of the previous consolidated form.\n\n**How behaviour, costs and decisions change**\n\n- Who decides: a delegate of CASA exercises the formal power under subregulation 39.001(1) to revoke and re‑issue these ADs.\n- Who pays: the cost of complying with each AD (inspections, parts, labour, downtime) continues to fall on aircraft owners/operators and maintenance providers; this instrument does not remove or add substantive compliance obligations.\n- Behaviour changes required: operators must continue to follow each AD’s directions. Because each AD is now a separate instrument, record‑keeping, compliance tracking and retrieval by operators or maintenance organisations may change (likely easier to cite and manage single AD numbers rather than a consolidated instrument).\n- Effects on private enterprise and markets: manufacturers, maintenance shops and parts suppliers continue to supply the work demanded by the ADs. Separating ADs into discrete instruments can reduce administrative friction for businesses that bill, schedule and document AD compliance, but it does not alter market obligations or competition in substance.\n\n**Trade‑offs, implementation risks and compliance burden**\n\n- Trade‑offs: the change is administrative rather than substantive. It trades a single consolidated legal instrument for many discrete instruments, which can improve clarity but increases the number of legal documents to manage.\n- Implementation risks: CASA must publish and maintain each separate AD correctly; failure to do so could cause confusion about the current authoritative text. Operators must ensure they consult the correct, re‑made AD text (the instrument specifies the re‑made ADs match the latest published edition).\n- Compliance burden: unchanged in substance. Some administrative burden may increase slightly because there are more individual instruments to monitor, but that can be offset by easier citation and retrieval of individual ADs.\n\n**Other observable features**\n\n- Several entries in the Schedule are annotated as “CANCELLED” (those cancelled ADs no longer impose obligations). Several entries are shown with amendment numbers (Amdt 1, 2, 3, etc.), indicating iterations of the substantive ADs are preserved in the re‑making process.\n- The instrument is narrow in subject matter: it concerns only ADs applying to Beechcraft 90 and 65‑90 (King Air) series aircraft as listed in the Schedule.\n\n(References: operative revocation/remaking clause; Schedule 1; subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998.)"},"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
