In view of the Continuous Airworthiness event of commercial aircraft, combined with the analysis of the impact on the cost and income of both manufacturers and airlines. Based on the analysis methods of manufacturers" life cycle cost and airlines" operating cost and income, this paper proposes an economic analysis model of Continuous Airworthiness activities of commercial aircraft, and analyzed the data of specific aircraft type. The model can be used analyze the initial operation cost of new model development according to different event classification and its cost and benefit impact, and further predict the Continuous Airworthiness cost of model maturity based on the learning curve theory.
