FAA Service Difficulty Reports Enriched Dataset

This dataset packages the FAA's annual Service Difficulty Reports into a single analysis-ready dataframe covering January 1, 1995 through May 29, 2026.

Each row represents one FAA service difficulty report describing an aircraft, engine, propeller, part, component, or structural maintenance issue submitted by operators or repair organizations. The dataset adds normalized timestamps, reporting-delay metrics, aircraft model-family grouping, issue-family classification, structural coordinate rollups, corrective-action summaries, grounding signals, and reproducible source URLs. The result is easier to use for maintenance intelligence, reliability monitoring, component-risk screening, fleet quality benchmarking, airworthiness research, and MRO analytics than the raw annual CSV downloads alone.

The source data comes directly from the FAA's official Service Difficulty Reports yearly CSV downloads.
