| Abstract: | This paper introduces the effect of 737NG TRU （transformer rectifier unit） in power system, and describes the direct current part of the whole power system, analyzes and summarizes the causes of TR UNIT fault lamp lighting, and tells the troubleshooting process combined with the cases, hoping to provide some help to overcome this kind of fault for aircraft maintenance industry. The failure cannot be released by MEL, which often results in flight delays, and this paper hopes to overcome the fault quickly in order to reduce flight delays through the analysis of the fault in-depth. |
