The directive applies to particular models and serial numbers of these six-seat single-engine planes.\n\n**Who must comply:**\n- Owners of PA-32-260 models with serial numbers: 32-03, 32-04, 32-1 through 32-7700016\n- Owners of PA-32-300 models with serial numbers: 32-15, 32-21, 32-40000 through 32-7740037, 32-7740039 through 32-7740053, 32-7740055 through 32-7740062, and 32-770064 through 32-7740069\n\n**The deadline:** The inspection must be done within 100 hours of flight time after 31 July 1977.\n\n**Why it matters:** Airworthiness Directives are legally binding safety orders. They typically issue when a manufacturer or regulator discovers a defect that could affect flight safety. Non-compliance means the aircraft cannot legally fly. This particular directive references Piper Service Bulletin No. 571, Part D — suggesting Piper Aircraft identified a fuel line issue requiring urgent attention to prevent potential engine failure or fire.\n\n**The bottom line:** If you own one of these specific Cherokee Six planes, you had to get your fuel lines checked within 100 flying hours of late July 1977, following the manufacturer's specified procedure."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-32-48-fuel-line-inspection","history":"/api/acts/ad-pa-32-48-fuel-line-inspection/history","analysis":"/api/acts/ad-pa-32-48-fuel-line-inspection/analysis","conflicts":"/api/acts/ad-pa-32-48-fuel-line-inspection/conflicts","importantCases":"/api/acts/ad-pa-32-48-fuel-line-inspection/important-cases","documents":"/api/acts/ad-pa-32-48-fuel-line-inspection/documents"}}
