波音737-300飞机'起飞爬升时引气压力低'故障隔离方法

摘要

Low pneumatic pressure during climb is a frequent and easily repeated fault in Boeing 737300 line maintenance. An pperational test of the wing TAl system at high engine power on the ground can locate the failed colmponent in the pneumatic system this fault isolalion procedure is testified to be easy and efficient.%在波音737-300型飞机的维护中,飞机起飞爬升时引气压力低是一个多发的、易重复的故障.从引气和机翼防冰系统的工作原理出发,通过发动机大功率状态下的机翼防冰系统操作测试来快速有效地确定引气系统中的失效部件.多次的验证测试表明,这个方法是易行的、高效的.
