Owners had to complete this within 100 flying hours after December 1984, following the manufacturer's guidelines (Piper Service Bulletin 791).\n\n**Why it matters:** As of **9 April 2009**, this specific maintenance requirement is officially dead. If you own one of these aircraft, you no longer need to perform this particular wiring modification to stay compliant with this rule (though all other safety regulations still apply). It’s essentially housekeeping—removing an outdated technical requirement that is no longer considered necessary for safety."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-46-7-oxygen-system-electrical-wiring-rerouting-cancelled","history":"/api/acts/ad-pa-46-7-oxygen-system-electrical-wiring-rerouting-cancelled/history","analysis":"/api/acts/ad-pa-46-7-oxygen-system-electrical-wiring-rerouting-cancelled/analysis","conflicts":"/api/acts/ad-pa-46-7-oxygen-system-electrical-wiring-rerouting-cancelled/conflicts","importantCases":"/api/acts/ad-pa-46-7-oxygen-system-electrical-wiring-rerouting-cancelled/important-cases","documents":"/api/acts/ad-pa-46-7-oxygen-system-electrical-wiring-rerouting-cancelled/documents"}}
