This involves inspecting or replacing hoses connected to the pitot probes—the external tubes that measure airspeed—to prevent water from accumulating inside them.\n\n**Why it matters:** Water trapped in pitot probe hoses can cause incorrect airspeed readings, which creates serious safety risks during flight. The work must be completed before 31 March 1992.\n\n**Note:** This requirement aligns with a French aviation safety directive (DGAC A/D 91-227-021(B))."}},"importantCases":[],"_links":{"self":"/api/acts/ad-a320-24-pitot-probe-hoses","history":"/api/acts/ad-a320-24-pitot-probe-hoses/history","analysis":"/api/acts/ad-a320-24-pitot-probe-hoses/analysis","conflicts":"/api/acts/ad-a320-24-pitot-probe-hoses/conflicts","importantCases":"/api/acts/ad-a320-24-pitot-probe-hoses/important-cases","documents":"/api/acts/ad-a320-24-pitot-probe-hoses/documents"}}
