What is it about?
The paper describes a process-based life cycle assessment that is used to ecologically evaluate the maintenance process of jet engine wash. Using a discrete-event driven framework, which can simulate the entire life cycle of an aircraft, a parameter study is carried out with regard to the frequency of the engine wash. Ecological but also economic consequences of these maintenance activities can thus be considered and analysed in detail.

Why is it important?
The results of this paper show that there is currently a large research gap in the environmental assessment of aviation maintenance activities. Due to environmental concerns and political and societal pressure, it is becoming increasingly important to consider environmental risks and consequences in addition to the economic factors.
Perspectives
Writing this paper and the reactions to it have shown that ecological considerations will gain in importance in the future. Therefore, appropriate ecological assessment methods need to be developed to support the decision-making process of manufacturers, operators as well as maintenance providers.
