As of 20 November 2008, this directive is dead and buried—aircraft owners need not comply with it anymore.\n\n**What the old rule required**\n\nThe original directive (issued decades ago) required owners of **Piper PA-25 Pawnee** aircraft to inspect and modify **jury struts**—the structural support bars that help hold the wings together—following a specific manufacturer instruction (Piper Service Letter No. 387). Owners were originally supposed to do this before September 1971.\n\n**Why it matters**\n\nIf you own or operate one of these agricultural aircraft, this cancellation removes a specific maintenance burden from your to-do list. The Civil Aviation Safety Authority has decided these particular jury strut inspections are no longer necessary for safety.\n\n**In short**: This is a formal notice saying *\"forget about that old jury strut rule—it doesn't apply anymore.\"*"}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-25-10-jury-struts-inspection-and-modification-cancelled","history":"/api/acts/ad-pa-25-10-jury-struts-inspection-and-modification-cancelled/history","analysis":"/api/acts/ad-pa-25-10-jury-struts-inspection-and-modification-cancelled/analysis","conflicts":"/api/acts/ad-pa-25-10-jury-struts-inspection-and-modification-cancelled/conflicts","importantCases":"/api/acts/ad-pa-25-10-jury-struts-inspection-and-modification-cancelled/important-cases","documents":"/api/acts/ad-pa-25-10-jury-struts-inspection-and-modification-cancelled/documents"}}
