It had to be completed within 100 hours of flying time after 31 December 1970.\n\n**Why it matters:**\nBattery drain can leave an aircraft without electrical power, which affects critical systems like radios, navigation equipment, and engine starting. This directive ensures these specific aircraft remain safe to fly by fixing the underlying design issue."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-31-14-battery-drain-relocation","history":"/api/acts/ad-pa-31-14-battery-drain-relocation/history","analysis":"/api/acts/ad-pa-31-14-battery-drain-relocation/analysis","conflicts":"/api/acts/ad-pa-31-14-battery-drain-relocation/conflicts","importantCases":"/api/acts/ad-pa-31-14-battery-drain-relocation/important-cases","documents":"/api/acts/ad-pa-31-14-battery-drain-relocation/documents"}}
