It removes a maintenance requirement that previously applied to owners of **Piper PA-25 Pawnee** aircraft (agricultural planes often used for crop-dusting).\n\n**What the old rule required**\nThe original directive (from 1975) required owners to install a safety cable connecting the main landing gear (undercarriage) to the fuselage frame within 100 hours of flight time. This was a uniquely Australian requirement, not based on manufacturer guidelines.\n\n**What changed**\nAs of **20 November 2008**, this requirement is officially cancelled. Owners of these aircraft no longer need to install this specific cable to comply with this rule.\n\n**Who is affected**\nOwners and operators of Piper PA-25 Pawnee series aircraft.\n\n**Why this matters**\nIf you own one of these planes, you no longer need to comply with this specific maintenance directive. However, other general aviation safety regulations still apply."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-25-7-main-undercarriage-safety-cable-installation-cancelled","history":"/api/acts/ad-pa-25-7-main-undercarriage-safety-cable-installation-cancelled/history","analysis":"/api/acts/ad-pa-25-7-main-undercarriage-safety-cable-installation-cancelled/analysis","conflicts":"/api/acts/ad-pa-25-7-main-undercarriage-safety-cable-installation-cancelled/conflicts","importantCases":"/api/acts/ad-pa-25-7-main-undercarriage-safety-cable-installation-cancelled/important-cases","documents":"/api/acts/ad-pa-25-7-main-undercarriage-safety-cable-installation-cancelled/documents"}}
