This is a temporary fix.\n\n**Why it matters:** Corrosion products (rust or similar damage) could cause the main landing gear to stay locked in the \"up\" position — meaning the wheels wouldn't come down for landing. This is obviously extremely dangerous. The door removal prevents this failure mode until a permanent solution is developed.\n\n**Deadline:** The work had to be completed before **15 March 1996**.\n\n**Key point:** This is an **interim measure** — not the final fix, but a necessary safety step to prevent accidents."}},"importantCases":[],"_links":{"self":"/api/acts/ad-tbm-700-16-main-landing-gear-inboard-doors","history":"/api/acts/ad-tbm-700-16-main-landing-gear-inboard-doors/history","analysis":"/api/acts/ad-tbm-700-16-main-landing-gear-inboard-doors/analysis","conflicts":"/api/acts/ad-tbm-700-16-main-landing-gear-inboard-doors/conflicts","importantCases":"/api/acts/ad-tbm-700-16-main-landing-gear-inboard-doors/important-cases","documents":"/api/acts/ad-tbm-700-16-main-landing-gear-inboard-doors/documents"}}
