The goal is to **prevent water from building up in the wing tips** between two specific structural ribs (N18 and N19). Water accumulation in aircraft wings can cause corrosion, add dangerous weight, or freeze and damage the structure.\n\n**When it had to be done:** Before **17 December 1995**.\n\n**Why it matters:** Water trapped in wing tips is a serious safety hazard. This AD ensures aircraft don't suffer structural damage or dangerous weight imbalances that could affect flight safety. The reference to the French aviation authority (DGAC) indicates this was a global safety issue originally identified in France.\n\n**Key point:** This is a **time-critical, mandatory safety instruction** — not optional guidance. Non-compliance would mean the aircraft is not legally airworthy."}},"importantCases":[],"_links":{"self":"/api/acts/ad-tbm-700-10-wing-tip-draining","history":"/api/acts/ad-tbm-700-10-wing-tip-draining/history","analysis":"/api/acts/ad-tbm-700-10-wing-tip-draining/analysis","conflicts":"/api/acts/ad-tbm-700-10-wing-tip-draining/conflicts","importantCases":"/api/acts/ad-tbm-700-10-wing-tip-draining/important-cases","documents":"/api/acts/ad-tbm-700-10-wing-tip-draining/documents"}}
