If your plane's serial number isn't on this list, this doesn't apply to you.\n\n**What you must do:** Replace the gaskets on the centre fuel tank fuel probes. These gaskets prevent fuel leaks, which could cause fires or engine failure.\n\n**How to do it:** Follow the manufacturer's instructions in Ted Smith Corporation Service Bulletin SB600-53.\n\n**When to do it:** Within 100 hours of flight time after 29 October 1976.\n\n**Why it matters:** Worn or faulty gaskets can allow fuel to leak from the centre tank, creating serious fire and explosion risks."}},"importantCases":[],"_links":{"self":"/api/acts/ad-tsa-600-5-centre-fuel-tank-fuel-probe-gasket-replacement","history":"/api/acts/ad-tsa-600-5-centre-fuel-tank-fuel-probe-gasket-replacement/history","analysis":"/api/acts/ad-tsa-600-5-centre-fuel-tank-fuel-probe-gasket-replacement/analysis","conflicts":"/api/acts/ad-tsa-600-5-centre-fuel-tank-fuel-probe-gasket-replacement/conflicts","importantCases":"/api/acts/ad-tsa-600-5-centre-fuel-tank-fuel-probe-gasket-replacement/important-cases","documents":"/api/acts/ad-tsa-600-5-centre-fuel-tank-fuel-probe-gasket-replacement/documents"}}
