When an aircraft in continuous airworthiness phase, the airplane maker needs to do the work of event collection, risk assessment, engineering survey and measure establishment, and then needs plenty of engineering data provided as input information, reference, also can provide the auxiliary analysis, these engineering data such as model data, fleet information, operation records, accident and events, and Airworthiness Directive. This paper studies the relationship between the continued airworthiness engineering data and Big Data, preliminary planning for the continued airworthiness engineering data system structure based on Big Data concept, and through the following automated way to realize the data acquisition and processing,to form the continuous airworthiness engineering database: first of all, using web crawler data acquisition technology to accurately obtain some public data. Secondly, the data is collected and processed by VBA language. Finally, analyzes the engineering data based on the mapping analysis method. The continuous airworthiness engineering database has been used for the daily operation of the continuous airworthiness system.
