Turnbuckles are adjustable metal fittings that keep control cables taut; if they fail or come loose, the pilot can lose control of the aircraft.\n\n**What must be done:**\n- Inspect these turnbuckles following the procedures in *Piper Service Bulletin No. 328* (the manufacturer's technical instructions)\n- Complete the inspection within **100 hours of flight time** after 31 March 1971\n\n**Who this affects:** Anyone operating these specific Pawnee aircraft in Australia—typically used for crop dusting and agricultural work.\n\n**Why it matters:** This prevents potentially catastrophic loss of control caused by mechanical failure of these critical hardware components."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-25-30-primary-control-cable-turnbuckles-inspection","history":"/api/acts/ad-pa-25-30-primary-control-cable-turnbuckles-inspection/history","analysis":"/api/acts/ad-pa-25-30-primary-control-cable-turnbuckles-inspection/analysis","conflicts":"/api/acts/ad-pa-25-30-primary-control-cable-turnbuckles-inspection/conflicts","importantCases":"/api/acts/ad-pa-25-30-primary-control-cable-turnbuckles-inspection/important-cases","documents":"/api/acts/ad-pa-25-30-primary-control-cable-turnbuckles-inspection/documents"}}
