This AD addresses a potential defect in the fuel selector valve that could affect fuel flow to the engine. Failure to comply could result in fuel starvation and engine failure, creating serious flight safety risks.\n\n**Compliance deadline:**\nThe work must be completed **within 100 hours of flight time** after 31 December 1976.\n\n**How to comply:**\nFollow the instructions in either:\n- Piper Service Bulletin No. 519A, **or**\n- FAA Airworthiness Directive 76-18-04, Amendment 39-2709"}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-32-43-fuel-selector-valve-inspection-and-replacement","history":"/api/acts/ad-pa-32-43-fuel-selector-valve-inspection-and-replacement/history","analysis":"/api/acts/ad-pa-32-43-fuel-selector-valve-inspection-and-replacement/analysis","conflicts":"/api/acts/ad-pa-32-43-fuel-selector-valve-inspection-and-replacement/conflicts","importantCases":"/api/acts/ad-pa-32-43-fuel-selector-valve-inspection-and-replacement/important-cases","documents":"/api/acts/ad-pa-32-43-fuel-selector-valve-inspection-and-replacement/documents"}}
