This prevents static electricity sparks that could ignite fuel vapours during refuelling.\n\n**Why it is being cancelled:**\nThese safety requirements are now covered by newer regulations — specifically **Civil Aviation Order 20.9** (operational rules) and modern aircraft design standards. Since the same safety protections exist elsewhere, this specific directive is redundant.\n\n**What this means:**\nAs of 20 December 2007, aircraft operators and maintainers no longer need to comply with this specific directive, provided they follow the current design standards and CAO 20.9 that cover the same issue."}},"importantCases":[],"_links":{"self":"/api/acts/ad-general-52-bonding-modification-cancelled","history":"/api/acts/ad-general-52-bonding-modification-cancelled/history","analysis":"/api/acts/ad-general-52-bonding-modification-cancelled/analysis","conflicts":"/api/acts/ad-general-52-bonding-modification-cancelled/conflicts","importantCases":"/api/acts/ad-general-52-bonding-modification-cancelled/important-cases","documents":"/api/acts/ad-general-52-bonding-modification-cancelled/documents"}}
