Think of it like a compulsory recall notice, but for aircraft instead of cars.\n\n**What it does:** It requires owners and operators of specific Beechcraft Bonanza aeroplanes to inspect and fix potential problems with their **flight controls** (the rudder and elevators — the moving surfaces that steer and pitch the aircraft).\n\n**Who it affects:**\n- **Beechcraft A36 models** with serial numbers E323 and E441 through E954\n- **All Model 36 series aircraft** that had their rudder and/or elevators shipped from the factory between 1 May 1973 and 1 July 1976\n\n**What must be done:** Aircraft owners must follow the instructions in **Beechcraft Service Instruction No. 0629-150, Revision II** — a technical document from the manufacturer detailing the required inspection or repair.\n\n**When it must be done:** Within **100 hours of flying time** after 31 January 1979, unless the work was already completed.\n\n**Why it matters:** Flight controls are critical to safe flight. This directive addresses a specific manufacturing or design defect discovered in certain Beechcraft components during a defined period. Non-compliance means the aircraft cannot legally fly."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-36-27-amdt-1-flight-controls","history":"/api/acts/ad-beech-36-27-amdt-1-flight-controls/history","analysis":"/api/acts/ad-beech-36-27-amdt-1-flight-controls/analysis","conflicts":"/api/acts/ad-beech-36-27-amdt-1-flight-controls/conflicts","importantCases":"/api/acts/ad-beech-36-27-amdt-1-flight-controls/important-cases","documents":"/api/acts/ad-beech-36-27-amdt-1-flight-controls/documents"}}
