Think of it as a compulsory \"recall notice\" for aircraft, but instead of fixing cars, it fixes planes.\n\n**What it requires:** Owners and operators of specific **Cessna 310 series aeroplanes** must **inspect the outboard aileron hinge** (the hinge connecting the wing's movable control surface to the wing itself) at least **every 100 hours of flight time**.\n\n**Which planes are affected:**\n- All Cessna 310 models with **serial numbers below 35392**\n- **Except** those already fitted with improved hinge parts numbered 0824006-1 or 0824006-2\n\n**Why it matters:** Aileron hinges are critical for controlling the aircraft's roll (banking left or right). A failed hinge could cause loss of control. This AD prevents catastrophic accidents by catching wear or damage before it becomes dangerous.\n\n**How to comply:** Follow either:\n- Cessna Service Letter No. 310-7, **or**\n- FAA Airworthiness Directive 57-4-1 (the American equivalent that Australia has adopted)\n\n**Who must follow this:** Anyone operating these specific Cessna aircraft in Australia — private owners, flying schools, charter operators, or anyone else with these planes on their register."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-2-outboard-aileron-hinge-inspection","history":"/api/acts/ad-cessna-310-2-outboard-aileron-hinge-inspection/history","analysis":"/api/acts/ad-cessna-310-2-outboard-aileron-hinge-inspection/analysis","conflicts":"/api/acts/ad-cessna-310-2-outboard-aileron-hinge-inspection/conflicts","importantCases":"/api/acts/ad-cessna-310-2-outboard-aileron-hinge-inspection/important-cases","documents":"/api/acts/ad-cessna-310-2-outboard-aileron-hinge-inspection/documents"}}
