An Airworthiness Directive is a mandatory safety notice that requires aircraft owners or operators to fix a specific problem.\n\n**What it does:** This directive applies to Piper PA-22 aircraft (Tri-Pacer and Colt models) with serial numbers 22-1 through 22-6087. It requires the installation of a fuse in the cigar lighter circuit (the 12V power outlet, similar to a car's cigarette lighter socket).\n\n**Why it matters:** Without a fuse, the cigar lighter circuit could overheat or cause a fire. This is a straightforward safety fix to prevent electrical fires in the cockpit.\n\n**Who must comply:** Anyone who owns or operates one of these specific Piper aircraft models.\n\n**When:** \"Forthwith\" means immediately — there's no grace period.\n\n**How to comply:** Follow either Piper Service Bulletin No. 163A or the US Federal Aviation Administration (FAA) Airworthiness Directive 58-16-1 for the correct procedure."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-22-11-cigar-lighter-circuit-provision-of-fuse","history":"/api/acts/ad-pa-22-11-cigar-lighter-circuit-provision-of-fuse/history","analysis":"/api/acts/ad-pa-22-11-cigar-lighter-circuit-provision-of-fuse/analysis","conflicts":"/api/acts/ad-pa-22-11-cigar-lighter-circuit-provision-of-fuse/conflicts","importantCases":"/api/acts/ad-pa-22-11-cigar-lighter-circuit-provision-of-fuse/important-cases","documents":"/api/acts/ad-pa-22-11-cigar-lighter-circuit-provision-of-fuse/documents"}}
