Reliability analysis of aeroplane tyres

Aeroplanes are repairable systems consisting of several non‐repairable parts; tyres are one of these. Proper record of failure data is valuable in interpreting the failure pattern, for comparative evaluation of the quality of tyres of various manufacturers, and for prediction of the future needs in a specified planning horizon or for specified operational hours. Analyses failure data of several aeroplane tyres in an aviation set‐up, and interprets these in a reliability framework. Three parameters Weibull model is found to be quite appropriate for reliability characterization of tyres. These reliability models can be effectively integrated into a computerized material requirement planning system of the aviation facility to forecast the number of tyres needed for a given planning horizon.
