This typically involves inspecting for cracks or damage and repairing or reinforcing the spar to prevent wing failure.\n\n**Deadline:** The work must be completed **before 1 September 1971**.\n\n**Why it matters:** The rear spar is critical to wing integrity. This directive addresses a specific safety risk that could lead to structural failure in flight if not corrected."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-180-2-right-wing-rear-spar","history":"/api/acts/ad-cessna-180-2-right-wing-rear-spar/history","analysis":"/api/acts/ad-cessna-180-2-right-wing-rear-spar/analysis","conflicts":"/api/acts/ad-cessna-180-2-right-wing-rear-spar/conflicts","importantCases":"/api/acts/ad-cessna-180-2-right-wing-rear-spar/important-cases","documents":"/api/acts/ad-cessna-180-2-right-wing-rear-spar/documents"}}
