This repeated inspection was required until a specific strengthening modification—welding extra metal plates called **doublers** onto the assembly—was performed.\n\n**What changes?**\nThis directive permanently removes that inspection requirement. The rule is no longer necessary because the required modification has been widely implemented over the decades since 1973.\n\n**Who is affected?**\nOwners, operators, and maintenance engineers of Piper PA-34 Seneca series aircraft. They no longer need to track compliance with the old inspection schedule or perform these specific rudder bar checks."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-34-10-rudder-bar-assembly-inspection-and-modification-cancelled","history":"/api/acts/ad-pa-34-10-rudder-bar-assembly-inspection-and-modification-cancelled/history","analysis":"/api/acts/ad-pa-34-10-rudder-bar-assembly-inspection-and-modification-cancelled/analysis","conflicts":"/api/acts/ad-pa-34-10-rudder-bar-assembly-inspection-and-modification-cancelled/conflicts","importantCases":"/api/acts/ad-pa-34-10-rudder-bar-assembly-inspection-and-modification-cancelled/important-cases","documents":"/api/acts/ad-pa-34-10-rudder-bar-assembly-inspection-and-modification-cancelled/documents"}}
