These rivets are essential for preventing **metal fatigue** — the weakening of aircraft structure over repeated flights.\n\n**Who must act:** Owners and operators of Dornier Model 328 aircraft with serial numbers 3064–3086.\n\n**What must be done:** Install the missing rivets following the technical instructions in the German aviation authority directive **LBA AD 97-328** (as detailed in Dornier Service Bulletin No. 328-57-239).\n\n**Deadline:** Before 31 March 2006 (unless already completed).\n\n**Why it matters:** Missing rivets compromise the structural integrity of the landing flaps. Without this fix, the flap arms could crack or fail due to fatigue, creating a serious flight safety risk."}},"importantCases":[],"_links":{"self":"/api/acts/ad-do-328-52-landing-flap-arm-rivets","history":"/api/acts/ad-do-328-52-landing-flap-arm-rivets/history","analysis":"/api/acts/ad-do-328-52-landing-flap-arm-rivets/analysis","conflicts":"/api/acts/ad-do-328-52-landing-flap-arm-rivets/conflicts","importantCases":"/api/acts/ad-do-328-52-landing-flap-arm-rivets/important-cases","documents":"/api/acts/ad-do-328-52-landing-flap-arm-rivets/documents"}}
