The aviation safety authority cancelled the underlying regulation (ANO 101.22) that authorised them, so this specific directive is now unnecessary. This removes compliance costs and maintenance burdens for affected aircraft owners."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-90-39-pre-certification-requirements-mods-cancelled","history":"/api/acts/ad-beech-90-39-pre-certification-requirements-mods-cancelled/history","analysis":"/api/acts/ad-beech-90-39-pre-certification-requirements-mods-cancelled/analysis","conflicts":"/api/acts/ad-beech-90-39-pre-certification-requirements-mods-cancelled/conflicts","importantCases":"/api/acts/ad-beech-90-39-pre-certification-requirements-mods-cancelled/important-cases","documents":"/api/acts/ad-beech-90-39-pre-certification-requirements-mods-cancelled/documents"}}
