| Abstract: | The display cooling fault of CRJ airplane would badly affect its normal flight, safety and maintenance cost. This article is for Shanghai Airline Company to study the frequently unscheduled remove of display cooling in CRJ airplanes by means of reliability analysis,so that it can get further analyses of the display cooling operation condition and the cause for "DISPLAY COOL". Then the reason why fault rate is a little higher can be found. By means of the reliability principle, it analyses the data, then calculates the UCL to find the alarm time. It compares MTBR with MTBUR to get a better period of substitution. |
