B737NG Engine Anti-icing Valve(TAI)Status Monitoring and Life Analysis Model
The probability of engine anti-icing valve(TAI)failure is not high,but the consequences of abnormal events such as aircraft takeoff interruption and return are quite serious,causing high economic losses to airlines.This article establishes a status monitoring model based on QAR data of part number 3215618-4/-5 TAI on 737NG aircraft.At the same time,this article analyzes its failure modes.Based on the repair data,it establishes a Weibull distribution model to analyze the lifespan of TAI's internal accessories.It is recommended that airlines take predictive and preventive measures for TAI failures based on the actual operating status trend of TAI and combined with life analysis.
