It requires owners to **replace the rear luggage compartment tie-down fittings** (the metal anchors used to secure cargo) with stronger, larger versions. \n\n**Who it affects:** Operators of DC-3 planes that were modified using specific older conversion drawings (DCA 1900 series).\n\n**What must be done:** Replace the existing tie-down fittings with larger ones as shown in updated technical drawings (DCA 2188 Issue 3), or follow alternative approved methods listed in older aviation notices.\n\n**Why it matters:** The original fittings were apparently too weak for safe cargo securing. This prevents luggage from breaking loose during flight, which could damage the aircraft or affect its balance."}},"importantCases":[],"_links":{"self":"/api/acts/ad-dc3-10-rear-luggage-compartment-tie-down-fittings-modification","history":"/api/acts/ad-dc3-10-rear-luggage-compartment-tie-down-fittings-modification/history","analysis":"/api/acts/ad-dc3-10-rear-luggage-compartment-tie-down-fittings-modification/analysis","conflicts":"/api/acts/ad-dc3-10-rear-luggage-compartment-tie-down-fittings-modification/conflicts","importantCases":"/api/acts/ad-dc3-10-rear-luggage-compartment-tie-down-fittings-modification/important-cases","documents":"/api/acts/ad-dc3-10-rear-luggage-compartment-tie-down-fittings-modification/documents"}}
