If the cockpit rear bulkhead has a bracket for mounting a first aid kit, that bracket poses a head-strike risk to occupants.\n\n**What operators must do (choose one):**\n- **Option 1:** Remove the bracket entirely; or  \n- **Option 2:** Replace the first aid kit with a protective block made of energy-absorbing material\n\n**Why it matters:**\nIn turbulence or a hard landing, a rigid metal bracket behind the pilot's head is essentially a head injury waiting to happen. This rule eliminates that risk by either removing the hard point or cushioning it.\n\n**Compliance deadline:**\nThe work must be completed within 100 hours of flight time after 31 July 1973."}},"importantCases":[],"_links":{"self":"/api/acts/ad-fu24-47-cockpit-bulkhead-modification","history":"/api/acts/ad-fu24-47-cockpit-bulkhead-modification/history","analysis":"/api/acts/ad-fu24-47-cockpit-bulkhead-modification/analysis","conflicts":"/api/acts/ad-fu24-47-cockpit-bulkhead-modification/conflicts","importantCases":"/api/acts/ad-fu24-47-cockpit-bulkhead-modification/important-cases","documents":"/api/acts/ad-fu24-47-cockpit-bulkhead-modification/documents"}}
