| Challenge: | Aircraft Maintenance Technicians spend up to 30% of their work time searching manuals . field reports indicate that up to 60% of technicians' time is spent searching for the correct procedure . |
| Approach: | They propose a semantic retrieval system that adapts LLM reranking to aviation MRO environments . evaluators construct revision-robust embeddings from ATA chapter hierarchies and use vision-language parsing to structure certified content. |
| Outcome: | The proposed system reduces the time spent searching for procedures in manuals by 90% . the system is based on a revision-robust embedding from ATA chapter hierarchies . |
