Q SERIES – MAINTENANCE PROGRAM EVOLUTION (Q SERIES C CHECK)

This project is a statistical study to verify whether the average interval between each heavy maintenance inspection checks, also known as C-Checks, can be escalated from 6000 Flight Hours (FH) to 8000 FH for Q400 aircraft. The internship serves as a crucial part of this heavily analysis- and review-oriented process. Interns are responsible for three stages. The first stage includes organizing issues logged by pilots and maintenance into categories of ATA 100 (Air Transportation Association of America) tasks set for C-Check maintenance and summarizing them. The second stage includes retrieving the Mean-Time between Failures (MTBF) for every component associated with these ATA tasks. Finally, the third task includes calculating the Mean-Time between Unscheduled Removals (MTBUR) rates of components listed in the second
stage. Based on the data collected, the analysts then conduct a Hypothesis Test to decide how maintenance intervals should be altered.
