I maintain A320, A321, and A330 fleets every day and know first-hand how much time can be lost hunting through the AMM. I’m now turning that experience into a mobile application whose core job is to walk a mechanic through genuine Airbus maintenance logic, step by step, the moment a fault code appears. The workflow I have in mind is simple for the user yet sophisticated behind the scenes. A technician selects or scans the reported fault; the app immediately serves the relevant AMM decision tree, predicts the likeliest branch using predictive analytics, and records each action the mechanic takes. At the end of every task the app stores the completed log so that subsequent interventions on the same tail number draw on real, aircraft-specific history rather than a blank slate. Data you will be working with starts as manually entered maintenance logs exported from our existing MIS. I’m open to broadening that to sensor feeds or historical fault libraries later, so a clean, extensible data pipeline matters. Key deliverables • Cross-platform mobile app (iOS + Android) built with a modern stack—React Native, Flutter, or another framework you are comfortable with. • Fault-tree engine that mirrors Airbus AMM logic and lets me update procedures without redeploying the whole app. • Predictive module (Python/TensorFlow, PyTorch, or similar) that ranks probable troubleshooting branches based on past fixes. • Secure local/remote storage of maintenance logs, plus export in CSV or JSON for MIS upload. • Clear documentation and a short video demo showing the workflow on an A320 use-case. Acceptance criteria 1. Given a sample logbook entry “F/CTL PRIM1 FAULT,” the app proposes the applicable AMM steps within 3 seconds on a mid-range Android device. 2. When the mechanic records each completed step, a timestamped record appears in the history screen and syncs to the cloud sandbox. 3. The predictive module displays a ranked list of next-likely faults with at least 70 % precision on the provided validation set. If building tools that keep aircraft moving safely and efficiently excites you, let’s talk code and calendars.
