Think of it as a \"recall notice\" for aircraft, but legally binding.\n\n**What it does:** It requires owners and operators of certain **Beechcraft 36 (Bonanza) series aeroplanes** to inspect or fix a problem with **seat recline actuators** (the hydraulic mechanisms that let seats tilt back).\n\n**Who it affects:** \n- All Beechcraft 36 models with specific serial numbers\n- Only planes equipped with \"Hydrolock\" brand seat recline actuators\n- Specifically applies to the **copilot seat** and **3rd and 4th seats** (typically rear passenger seats)\n\n**The safety problem:** The manufacturer found cases where these seat mechanisms could **move unexpectedly** (inadvertent actuation). During certain phases of flight, a seat suddenly reclining could distract the crew or interfere with controls — creating a safety hazard.\n\n**What must be done:** Operators must follow the instructions in **Beechcraft Service Bulletin No. 2175 Revision 1** — a technical document from the manufacturer detailing the inspection or repair procedure.\n\n**When it must be done:** Within **100 hours of flight time** after 3 December 1987, or at the next scheduled inspection for the aircraft's Maintenance Release (whichever comes later). A Maintenance Release is basically the aircraft's \"roadworthy certificate\" — required paperwork showing the plane is safe to fly.\n\n**Why it matters:** This prevents potentially dangerous distractions or physical interference during critical flight phases like takeoff or landing. It references a corresponding US Federal Aviation Administration directive (FAA AD 87-18-06), showing this was a coordinated international safety response."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-36-32-seat-recline-actuators","history":"/api/acts/ad-beech-36-32-seat-recline-actuators/history","analysis":"/api/acts/ad-beech-36-32-seat-recline-actuators/analysis","conflicts":"/api/acts/ad-beech-36-32-seat-recline-actuators/conflicts","importantCases":"/api/acts/ad-beech-36-32-seat-recline-actuators/important-cases","documents":"/api/acts/ad-beech-36-32-seat-recline-actuators/documents"}}
