Unscheduled maintenance events have a significant impact on airlines performance and network operations. Some events can have its consequences minimized by simple actions due to its simplicity and lack of influence in the safe conduction of a flight.
This study aimed on collecting data regarding the cost and consequences of ground turn back events in the Airbus A320 family. The study suggested that after the implementation of proper supporting regulation on Crew Applied MEL, money would be saved as well as network disruption consequences could be avoided.
The data presented in this study reflects current Brazilian legislation, and data from reliability engineering, targeting to present the overall impact of Gate Returns during the taxi-out phase.
The research presented an estimated combined savings of U$1.239.833, coming from 14.769 minutes and 221 flight delays that could have been avoided in a five-year period (2016-2021).
Crew Applied MEL procedures are widely known worldwide but lacks on supportive regulations in Brazil. Therefore, this study also found an opportunity to regulations improvement in order to allow airlines to implement Crew Applied MEL.
