In order to solve the breakdown problem of a certain type of UAV during testing flight, the method of failure tree analysis is used to analyze the fault. Based on the analysis of the breakdown of a turbo-jet engine during testing flight, the analysis and location process of the breakdown problem is provided, corresponding improving measures have been raised and verified. The result shows that it is a good reference to the analysis of failure to zero and the disposal of typical failure of the engine and for the engine designers and users.
