The rule is no longer in force.\n\n**Who it affects:** Owners and operators of Piper PA-32 (Cherokee Six) series aeroplanes (though given the 1977 compliance deadline, most affected aircraft would have long since been modified).\n\n**Why it matters:** The Civil Aviation Safety Authority has determined this particular safety modification is no longer necessary—likely because all affected aircraft have already been modified, the part has been redesigned, or the original safety risk no longer exists."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-32-52-electric-pitch-trim-switch-modification-cancelled","history":"/api/acts/ad-pa-32-52-electric-pitch-trim-switch-modification-cancelled/history","analysis":"/api/acts/ad-pa-32-52-electric-pitch-trim-switch-modification-cancelled/analysis","conflicts":"/api/acts/ad-pa-32-52-electric-pitch-trim-switch-modification-cancelled/conflicts","importantCases":"/api/acts/ad-pa-32-52-electric-pitch-trim-switch-modification-cancelled/important-cases","documents":"/api/acts/ad-pa-32-52-electric-pitch-trim-switch-modification-cancelled/documents"}}
