Due to the direct influences to the aircraft operation safety, economics and customer comfortability, both airframers and airliners pay much attention on the fault diagnosis of APU sytsem. But during the design process of APU, it is impossible to detect and isolate all of the faults or failures. So, in order to solve the detection issue of complicated APU faults, taking start button fault and abnoraml start time of B737 as two examples, this article intend to propose the application of post flight QAR data decoding, which can enable maintenaners to review continuous change of APU related parameters.Then fault diagnosis level of APU can be raised. Practices has proved that, with the help of post flight QAR data decoding results, the fault diagnosis level of APU and aircraft wil be enhanced, the airliners’ operation and maintenance will be faciliated, and finally utilization of the fleet will be promoted.
