Owners had to complete the work within 50 flight hours after October 1981.\n\n**Why it's being scrapped:**\nBecause the compliance deadline passed nearly three decades ago, every affected aircraft would have already completed the rebalancing. The rule is now redundant paperwork, so the Civil Aviation Safety Authority has cancelled it effective 4 June 2009.\n\n**What this means:**\nNo aircraft owner needs to comply with this directive anymore. It has been removed from the books to reduce administrative clutter."}},"importantCases":[],"_links":{"self":"/api/acts/ad-swsa226-35-aileron-static-rebalance-incorporation-cancelled","history":"/api/acts/ad-swsa226-35-aileron-static-rebalance-incorporation-cancelled/history","analysis":"/api/acts/ad-swsa226-35-aileron-static-rebalance-incorporation-cancelled/analysis","conflicts":"/api/acts/ad-swsa226-35-aileron-static-rebalance-incorporation-cancelled/conflicts","importantCases":"/api/acts/ad-swsa226-35-aileron-static-rebalance-incorporation-cancelled/important-cases","documents":"/api/acts/ad-swsa226-35-aileron-static-rebalance-incorporation-cancelled/documents"}}
