You must follow the exact instructions in three specific Beechcraft Service Bulletins: B50-No. 22, C50-No. 11, and D50-No. 4.\n\n**When:** Immediately (the term used is \"forthwith,\" meaning without delay).\n\n**Why it matters:** Faulty magneto ground leads can cause engine misfires or failure to shut down properly, creating serious safety risks during flight. This directive forces operators to fix the issue before further flight."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-50-7-magneto-ground-leads","history":"/api/acts/ad-beech-50-7-magneto-ground-leads/history","analysis":"/api/acts/ad-beech-50-7-magneto-ground-leads/analysis","conflicts":"/api/acts/ad-beech-50-7-magneto-ground-leads/conflicts","importantCases":"/api/acts/ad-beech-50-7-magneto-ground-leads/important-cases","documents":"/api/acts/ad-beech-50-7-magneto-ground-leads/documents"}}
