This only applied to aircraft fitted with a voltage regulator selector switch, and had to be done immediately (\"forthwith\").\n\n**What it says now:** **This rule is cancelled.** As of 18 December 2008, the fuse installation requirement no longer applies. Owners and operators of these aircraft do not need to install these fuses to comply with this directive.\n\n**Why it matters:** If you own one of these aircraft, you are no longer legally required to perform this specific modification, though you should ensure your aircraft meets other applicable safety standards."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-30-11-amdt-1-alternator-field-fuse-installation-cancelled","history":"/api/acts/ad-pa-30-11-amdt-1-alternator-field-fuse-installation-cancelled/history","analysis":"/api/acts/ad-pa-30-11-amdt-1-alternator-field-fuse-installation-cancelled/analysis","conflicts":"/api/acts/ad-pa-30-11-amdt-1-alternator-field-fuse-installation-cancelled/conflicts","importantCases":"/api/acts/ad-pa-30-11-amdt-1-alternator-field-fuse-installation-cancelled/important-cases","documents":"/api/acts/ad-pa-30-11-amdt-1-alternator-field-fuse-installation-cancelled/documents"}}
