These connectors, made by T.J. Electronics, can develop internal short circuits that cause the fuel valve to rapidly switch between open and closed positions without warning — a serious flight safety hazard.\n\n**Deadline:**\nAll affected helicopters had to comply with this directive before 1 March 1988.\n\n**Why it matters:**\nThe faulty connectors could cause unexpected fuel flow interruptions, potentially leading to engine failure or loss of control."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-212-38-engine-fuel-valve-electrical-connectors-p-no-ms3456w14s-5s","history":"/api/acts/ad-bell-212-38-engine-fuel-valve-electrical-connectors-p-no-ms3456w14s-5s/history","analysis":"/api/acts/ad-bell-212-38-engine-fuel-valve-electrical-connectors-p-no-ms3456w14s-5s/analysis","conflicts":"/api/acts/ad-bell-212-38-engine-fuel-valve-electrical-connectors-p-no-ms3456w14s-5s/conflicts","importantCases":"/api/acts/ad-bell-212-38-engine-fuel-valve-electrical-connectors-p-no-ms3456w14s-5s/important-cases","documents":"/api/acts/ad-bell-212-38-engine-fuel-valve-electrical-connectors-p-no-ms3456w14s-5s/documents"}}
