Aviation Data Analytics in the Cloud

Abstract

Maintenance, Repair, and Overhaul (MRO) in commercial aviation refers to the practices and systems airlines use to ensure aircraft remain airworthy, efficient, and compliant with regulations over time. It’s a broad term, covering everything from routine inspections to unscheduled repairs and full component overhauls. In daily operations, MRO shows up in ways that might seem invisible to passengers—like a component swap during a turnaround or the tracking of wear patterns through maintenance logs. Airlines rely heavily on reliability data, both historical and real-time, to anticipate failures before they happen and to schedule work without disrupting flight schedules. This data—collected from flight hours, shop findings, onboard sensors, even crew reports—feeds into reports that are often requested by customers or suppliers. Sometimes it’s messy, incomplete, or needs stitching together from different sources. But when it works, it helps close feedback loops, improve parts sourcing, and meet contractual obligations.
