Study on Level of Repair Analysis for Amphibious Aircraft Wading Structure

Abstract

Level of repair analysis(LORA)is an important part of maintenance engineering analysis for amphibious aircraft wading structure.There are many studies mainly focusing on LORA of civil aircraft,shipboard aircraft,vehicles,ships and so on in the domestic and overseas,while studies on LORA of amphibious aircraft wading structure are few.Based on this,the process and method of LORA for the wading structure of amphibious aircraft are studied in this paper.A three-level repair model of the wading structure is established,and the LORA process of the wading structure is proposed.An economical LORA(ELORA)model for three-level repair of wading structure is established,and the cost factors to be considered for ELORA are given.The approach switch on the wading cabin door of an amphibious aircraft is taken as an example to carry out ELORA.The results show that the approach switch should be repaired in intermediate-level depot,which is in accordance with reality,and the ELORA model used on wading structure is feasible.
