If your aircraft's serial number isn't on this list, this directive doesn't apply to you.\n\n**What you must do:**\nWithin **100 hours of flight time** (counted from 25 November 1969), you must complete an inspection of the rear fuselage following the procedures set out in **Piper Service Bulletin No. 296**.\n\n**Why it matters:**\nThis directive addresses specific safety concerns about potential structural failures in the rear fuselage. Airworthiness Directives are legally binding under the Civil Aviation Regulations. Flying without completing this inspection (or exceeding the 100-hour limit) violates aviation law and compromises safety."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-23-38-rear-fuselage-inspection","history":"/api/acts/ad-pa-23-38-rear-fuselage-inspection/history","analysis":"/api/acts/ad-pa-23-38-rear-fuselage-inspection/analysis","conflicts":"/api/acts/ad-pa-23-38-rear-fuselage-inspection/conflicts","importantCases":"/api/acts/ad-pa-23-38-rear-fuselage-inspection/important-cases","documents":"/api/acts/ad-pa-23-38-rear-fuselage-inspection/documents"}}
