The scope remains tightly constrained to this specific airworthiness issue. As Amendment 1, it likely clarifies or adjusts inspection intervals from the original 1969 directive, but does not expand the scope beyond the original safety purpose."},"complexity_factors":["Extremely short document (under 200 words)","Only 2 defined compliance actions","No nested exceptions or conditional logic","Simple applicability test (model + component type)","References only 2 external technical documents (Cessna Service Letters)","No cross-referencing to other legislation or regulations"],"plain_english_summary":"This is an **Airworthiness Directive (AD)** — essentially a mandatory safety notice issued by Australia's Civil Aviation Safety Authority (CASA) for aircraft.\n\n**What it does:**\nIt requires owners and operators of **Cessna 336 series aeroplanes** (a twin-engine aircraft) to conduct regular inspections of their **plastic control wheels** (the steering yoke the pilot holds).\n\n**Who it affects:**\nAnyone who owns or operates a Cessna 336 aircraft that has plastic control wheels installed.\n\n**What must be done:**\nTwo separate inspections are required on an ongoing basis:\n- **Every 100 hours of flight time:** Inspect following Cessna Service Letter 62-44\n- **Every 500 hours of flight time:** Inspect following Cessna Service Letter 64-8\n\nBoth inspection schedules started from **12 May 1969**.\n\n**Why it matters:**\nPlastic control wheels can degrade, crack, or fail over time. A broken control wheel in flight could cause loss of control of the aircraft. This directive ensures potential defects are caught before they become dangerous.\n\n**Key point:** This is **Amendment 1** of the original directive, meaning the requirements have been updated from a previous version."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-336-3-amdt-1-plastic-control-wheel-inspection","history":"/api/acts/ad-cessna-336-3-amdt-1-plastic-control-wheel-inspection/history","analysis":"/api/acts/ad-cessna-336-3-amdt-1-plastic-control-wheel-inspection/analysis","conflicts":"/api/acts/ad-cessna-336-3-amdt-1-plastic-control-wheel-inspection/conflicts","importantCases":"/api/acts/ad-cessna-336-3-amdt-1-plastic-control-wheel-inspection/important-cases","documents":"/api/acts/ad-cessna-336-3-amdt-1-plastic-control-wheel-inspection/documents"}}
