The serial numbers are listed precisely in the document.\n\n**Why it matters:**\nDuring manufacturing, some rivets required for the pressure cabin's fatigue certification were accidentally left out. Missing rivets could weaken the structure that keeps the cabin pressurized at high altitude, potentially leading to structural failure over time.\n\n**What must be done:**\n- Inspect the fuselage and install missing rivets following Piper Service Bulletin No. 959\n- Complete this by the next scheduled maintenance check (within 110 flight hours) after 22 July 1993\n- If already done, no further action needed"}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-46-25-fuselage-rivet-installation","history":"/api/acts/ad-pa-46-25-fuselage-rivet-installation/history","analysis":"/api/acts/ad-pa-46-25-fuselage-rivet-installation/analysis","conflicts":"/api/acts/ad-pa-46-25-fuselage-rivet-installation/conflicts","importantCases":"/api/acts/ad-pa-46-25-fuselage-rivet-installation/important-cases","documents":"/api/acts/ad-pa-46-25-fuselage-rivet-installation/documents"}}
