This protective device must be positioned as close as possible to where the cable connects to the battery relay.\n\n**Why this matters**\nThe modification prevents electrical fires. Without a fuse or circuit breaker, a fault in the alternator cable could overheat and ignite, or damage the aircraft's electrical system. The device acts like a safety switch, cutting power if the current exceeds safe levels.\n\n**Who is affected**\nOnly Cessna 337 models within the specified serial number range.\n\n**Compliance**\nAircraft operators must complete this modification within 200 hours of flight time after 31 January 1975."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-337-16-alternator-cable-protection-modification","history":"/api/acts/ad-cessna-337-16-alternator-cable-protection-modification/history","analysis":"/api/acts/ad-cessna-337-16-alternator-cable-protection-modification/analysis","conflicts":"/api/acts/ad-cessna-337-16-alternator-cable-protection-modification/conflicts","importantCases":"/api/acts/ad-cessna-337-16-alternator-cable-protection-modification/important-cases","documents":"/api/acts/ad-cessna-337-16-alternator-cable-protection-modification/documents"}}
