Track: Lean Six Sigma

Abstract

The purpose of this research study aimed to determine different factors and conditions affecting the tire tread wear of a Dornier 328 aircraft. So many studies and experiments were done to reduce aircraft tire wear, but none were
patented because most literature describing the physical process that causes aircraft tire rubber to vaporize under landing loads is sparse, although multiple studies have been reported in the automotive field. The methodology used
was the Six Sigma and DMAIC methodology. To analyze the gathered data from the maintenance logbook of an aircraft charterer, the researcher also used the Design of Experiment. Based on the results of the experiment, three
factors are statistically significant to the aircraft tire wear: the experience of the pilot, the length of the runway, and the age of the aircraft. Also, tests were used to determine the interaction between factors, and as a result, the 2-way
interaction of pilot and runway gives the most significant interaction. These findings will help the charterer reduce their operational costs by minimizing the tire tread wear and also aid them in planning their flight schedules in
consideration of the manning of the aircraft and its destinations. Also, a decrease in rubber production for new tires will have a positive environmental impact. The findings will also serve as a guide for further studies by future
researchers on other factors that might be contributory to the reduction of tire tread wear which the researcher was not able to consider due to some constraints.
