The fix removed low points in the tubing where water could collect and freeze, which could cause incorrect airspeed readings.\n\n**Why it's being cancelled:** The deadline to complete these modifications was 31 December 1990. Since all affected aircraft would have been inspected and fixed nearly 20 years ago, the rule is now redundant.\n\n**What happens now:** The cancellation removes the legal requirement from the books, though in practice this changes nothing for operators because the work was completed decades ago. This is essentially regulatory housekeeping."}},"importantCases":[],"_links":{"self":"/api/acts/ad-a320-10-standby-pitot-line-cancelled","history":"/api/acts/ad-a320-10-standby-pitot-line-cancelled/history","analysis":"/api/acts/ad-a320-10-standby-pitot-line-cancelled/analysis","conflicts":"/api/acts/ad-a320-10-standby-pitot-line-cancelled/conflicts","importantCases":"/api/acts/ad-a320-10-standby-pitot-line-cancelled/important-cases","documents":"/api/acts/ad-a320-10-standby-pitot-line-cancelled/documents"}}
