The inspection must follow Piper Service Bulletin No. 503A.\n\n**Who it affects:** Owners and operators of Piper PA-32R-300 aircraft with serial numbers in the ranges: 32R-7680001 to 32R-7680132, 32R-7680134 to 32R-7680175, 32R-7680177 to 32R-7680200, 32R-7680202 to 32R-7680204, and 32R-7680207 to 32R-7780411.\n\n**When to comply:** Within 100 hours of flight time after 25 November 1977.\n\n**Why it matters:** Fuel line defects can cause engine failure or fire. This directive ensures a known defect is caught before it causes an accident. The note clarifies that if you already complied with the earlier version of this directive, you're still compliant — you don't need to do it again."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-32-39-amdt-1-fuel-line-inspection","history":"/api/acts/ad-pa-32-39-amdt-1-fuel-line-inspection/history","analysis":"/api/acts/ad-pa-32-39-amdt-1-fuel-line-inspection/analysis","conflicts":"/api/acts/ad-pa-32-39-amdt-1-fuel-line-inspection/conflicts","importantCases":"/api/acts/ad-pa-32-39-amdt-1-fuel-line-inspection/important-cases","documents":"/api/acts/ad-pa-32-39-amdt-1-fuel-line-inspection/documents"}}
