The work must follow the instructions in **Rex Aviation Technical Memo No. TM21**.\n\n**Who it affects:**\nOnly aircraft with serial numbers from **188-0001 to 188-02348** that have **not** been upgraded with specific later-model hinge parts (including a particular shim, part number 1620089-1).\n\n**When you must comply:**\nThe inspection and any necessary repairs must be carried out **every 100 hours of flight time**.\n\n**Why it matters:**\nFatigue or cracks in the aileron spar could cause the control surface to fail in flight, potentially leading to loss of control during low-level agricultural operations."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-188-7-amdt-1-aileron-spar","history":"/api/acts/ad-cessna-188-7-amdt-1-aileron-spar/history","analysis":"/api/acts/ad-cessna-188-7-amdt-1-aileron-spar/analysis","conflicts":"/api/acts/ad-cessna-188-7-amdt-1-aileron-spar/conflicts","importantCases":"/api/acts/ad-cessna-188-7-amdt-1-aileron-spar/important-cases","documents":"/api/acts/ad-cessna-188-7-amdt-1-aileron-spar/documents"}}
