Poor welding could cause the tube to fail in flight.\n\n**When:**\nThe work must be completed within 100 hours of flight time after 31 July 1987, or at the next scheduled inspection for the aircraft's Maintenance Release—whichever occurs later.\n\n**Why it matters:**\nA failed flap actuator could prevent the pilot from properly extending or retracting the flaps, seriously compromising control during critical phases of flight."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-46-13-flap-actuator-tube","history":"/api/acts/ad-pa-46-13-flap-actuator-tube/history","analysis":"/api/acts/ad-pa-46-13-flap-actuator-tube/analysis","conflicts":"/api/acts/ad-pa-46-13-flap-actuator-tube/conflicts","importantCases":"/api/acts/ad-pa-46-13-flap-actuator-tube/important-cases","documents":"/api/acts/ad-pa-46-13-flap-actuator-tube/documents"}}
