The directive was issued over 30 years ago to fix a specific manufacturing defect, and by now all affected altimeters should have been replaced. The unsafe condition has been eliminated through compliance with the original rule.\n\n**What happens now**\nAs of 20 December 2007, aircraft owners no longer need to comply with this specific directive. The cancellation is automatic—no action is required by aircraft operators."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-33-22-internally-lighted-altimeters-cancelled","history":"/api/acts/ad-beech-33-22-internally-lighted-altimeters-cancelled/history","analysis":"/api/acts/ad-beech-33-22-internally-lighted-altimeters-cancelled/analysis","conflicts":"/api/acts/ad-beech-33-22-internally-lighted-altimeters-cancelled/conflicts","importantCases":"/api/acts/ad-beech-33-22-internally-lighted-altimeters-cancelled/important-cases","documents":"/api/acts/ad-beech-33-22-internally-lighted-altimeters-cancelled/documents"}}
