They had 25 flight hours to get it done.\n\n**What's changed**\nAs of **23 October 2008**, that requirement is **cancelled**. Owners and maintenance crews no longer need to perform this modification or keep records proving compliance.\n\n**Who is affected**\nAnyone who owns, operates, or maintains a Piper PA-34 Seneca series aircraft. This removes a decades-old maintenance burden, though any modifications already completed can remain in place."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-34-8-wing-walk-inspection-and-modification-cancelled","history":"/api/acts/ad-pa-34-8-wing-walk-inspection-and-modification-cancelled/history","analysis":"/api/acts/ad-pa-34-8-wing-walk-inspection-and-modification-cancelled/analysis","conflicts":"/api/acts/ad-pa-34-8-wing-walk-inspection-and-modification-cancelled/conflicts","importantCases":"/api/acts/ad-pa-34-8-wing-walk-inspection-and-modification-cancelled/important-cases","documents":"/api/acts/ad-pa-34-8-wing-walk-inspection-and-modification-cancelled/documents"}}
