Abstract:

Reliable operation of pressurization system is critically important for the crew's life safety. To quickly and accurately determine the failure of pressurization system and improve the efficiency of routes troubleshooting,the fault of B737-300 aircraft's automatic pressurization system is chosen to introduce the basement and method of fault tree establishment,making qualitative and quantitative analysis for the reliability of pressurization control system. This method has been initially verified in the process of practical routes troubleshooting,and has big significance in improving the efficiency of pressurization system's troubleshooting.

Key words: B737-300, pressurization system, fault tree, failure analysis
