This involves fitting a support bracket to prevent the exhaust pipe from vibrating loose, cracking, or failing due to engine heat and stress.\n\n**Who it affects:** Only **turbocharged Cessna 320 aircraft** with serial numbers from **320D0001 to 320F0045** (covering the D, E, and F model variants).\n\n**Why it matters:** Without this support, the exhaust tailpipe could fracture in flight. This creates serious risks: carbon monoxide (a deadly gas) could leak into the cabin and incapacitate the crew, or hot exhaust could damage surrounding aircraft structure.\n\n**Compliance:** The modification had to be completed before **1 January 1976**, following the technical instructions in Cessna Service Letter ME75-17."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-320-24-exhaust-tailpipe-support-kit-installation","history":"/api/acts/ad-cessna-320-24-exhaust-tailpipe-support-kit-installation/history","analysis":"/api/acts/ad-cessna-320-24-exhaust-tailpipe-support-kit-installation/analysis","conflicts":"/api/acts/ad-cessna-320-24-exhaust-tailpipe-support-kit-installation/conflicts","importantCases":"/api/acts/ad-cessna-320-24-exhaust-tailpipe-support-kit-installation/important-cases","documents":"/api/acts/ad-cessna-320-24-exhaust-tailpipe-support-kit-installation/documents"}}
