Multiple tiers of inspection and upkeep are in place for aircraft. There are four primary kinds of checks, designated by the letters A, B, C, and D. (Wiede et al, 2022). Companies that specialize in maintenance, repair, and overhaul (MRO) are able to fix any issues discovered during these examinations. However, it is challenging to schedule these chores in a way that does not disrupt MRO operations and the turnaround time. By keeping the plane grounded for as little time as possible for inspections and repairs, the best maintenance schedule is attained. Uncertainties during airplane maintenance always lead to increased downtime or flight delays. It is the goal of this study to pinpoint the sources of the scheduling difficulties encountered during aircraft maintenance and inspection, as well as provide practical suggestions for resolving these problems. Unavailability of OEM supplies, unanticipated maintenance, and turnaround time are just a few of the difficulties that will be covered in this discussion.

The difficult process of arranging many tasks for numerous aircraft is the issue in planning airplane maintenance, which is often done in work packages (regular work, component change, deferred faults, modifications, inspections, etc). (Albakkoush et al, 2021). A potential remedy for complex planning is discrete event simulation (DES). To model the time it will take all necessary operations as well as unforeseen jobs, a simulation of line maintenance using DES is tested. A-Check completion took two extra hours as a result of damaged components or lacking tools, according to the simulation’s results. MRO operators must update their planning to account for such contigencies, and switching to work packages and running it through DES can reduce timing and result in a much better maintenance program with minimal deviation from the plan. By modifying the simulation to fit the circumstances of heavy maintenance, this can also be used for regular maintenance.

The goal of this study is to draw attention to the scheduling difficulties associated with aircraft maintenance and inspection. This study has identified a number of interrelated variables that have an impact on scheduling difficulties for MRO businesses. The majority of schedule maintenance issues are caused by important factors such unscheduled maintenance, OEM supply, and turnaround time. A small delay in maintenance inspections might have a big impact on the operations. More delays mean more pressure to speed up procedures, require more equipment and spare parts, and guarantee that the delayed aircraft would finish on schedule. Implementing DES along with maintenance planning is one technique to make more room for unscheduled taskings, this might be done for example by rearranging work packages.
