Abstract
The aim of this study is to investigate whether the size of airline operations has any statistically significant effect on the costs of its aircraft maintenance. By investigating the impact of the extent of operations on unit costs of carriers, it was inspected the existence of economies of scale in providing maintenance services. Through an econometric model of maintenance costs, it was estimated the influence of key drivers such as the aircraft average stage length, aircraft size and load factors. It was performed an application to the Brazilian airline industry. The empirical model makes use of a Fixed-Effects Estimator (FE), using a four-dimensional panel data of flight segments, carriers and equipment over a period of ten years. Results showed support for the hypothesis of scale economies in maintenance services.
