A Compliance-Preserving Retrieval System for Aircraft MRO Task Search (arXiv 2511.15383)

Overview

This forum entry summarizes an arXiv paper (November 2025) by Byungho Jo:

• Paper: A Compliance-Preserving Retrieval System for Aircraft MRO Task Search
• Author: Byungho Jo
• Link: https://arxiv.org/abs/2511.15383
• Category: Maintenance, Repair, Manufacturing

Key points

• The paper proposes a retrieval system for aircraft MRO (Maintenance, Repair, and Overhaul) task search that explicitly preserves compliance constraints, rather than optimizing retrieval relevance alone.
• The motivation is that aviation maintenance task information is embedded in heavily regulated documentation; retrieval in this domain must respect regulatory and procedural compliance requirements.
• The work sits at the intersection of information retrieval and industrial/maintenance knowledge systems, alongside related efforts applying LLMs and RAG to manufacturing and aerospace maintenance knowledge access.

Context within the IR landscape

The forum entry situates the paper within the broader evolution of information retrieval:

• Classic cascades (recall → reranking → generation) remain dominant, but LLM-era systems increasingly treat retrieval strategy itself as a learnable, agentic decision.
• For safety-critical domains like aviation maintenance, hard constraints such as latency, cost, explainability, and compliance/safety policy cannot be sacrificed for benchmark gains.
• Evaluation in such settings should go beyond offline metrics (nDCG, Recall@k) toward task success, citation accuracy, and human-audited compliance checks.

Notes for readers

• Detailed quantitative results are not reproduced here; verify numbers against the original PDF before citing.
• Engineers evaluating this line of work should additionally consider index update frequency, embedding version management, failure modes (empty retrieval, incorrect tool calls), and compliance auditing of outputs.
