This modification had to be completed within 100 hours of flight time after December 1970.\n\n**Why it matters now:** The Civil Aviation Safety Authority (CASA) has cancelled this directive because all affected aircraft in Australia have already been modified. The safety issue has been resolved fleet-wide, making the mandatory requirement obsolete.\n\n**What this means:**\n- **Effective date:** 31 July 2008\n- **Action required:** None — this simply removes a completed requirement from the books\n- **Legal effect:** The previous directive is no longer enforceable (though the physical modifications remain on the aircraft)"}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-31-14-battery-drain-relocation-cancelled","history":"/api/acts/ad-pa-31-14-battery-drain-relocation-cancelled/history","analysis":"/api/acts/ad-pa-31-14-battery-drain-relocation-cancelled/analysis","conflicts":"/api/acts/ad-pa-31-14-battery-drain-relocation-cancelled/conflicts","importantCases":"/api/acts/ad-pa-31-14-battery-drain-relocation-cancelled/important-cases","documents":"/api/acts/ad-pa-31-14-battery-drain-relocation-cancelled/documents"}}
