【摘要】 某民航班机在飞行途中座舱内发现冒烟及微弱闪光,地面检查发现P6板后部有一电缆有燃烧痕迹。通过对受损导线的检查分析,结果表明,两根导线之间产生强烈电弧是引起飞机空中电缆起火的原因。而导致这两根导线之间产生电弧的直接原因则是导线在固定卡子部位出现了严重挤压和磨损。更多还原

【Abstract】 A civil aviation flight smoked and sparked in cockpit during cruise. The following inspection on the ground showed that a piece of wire was burnt and broken on P6 panel. The analysis results on damaged wires show that strong arc occurring between two pieces of wire caused the cable to catch fire during cruise. The main cause for arcing is the severe extrusion and abrasion on the fixed part of the wires.更多还原
