Augmented reality (AR) in aerospace maintenance is being used to overlay step-by-step instructions, 3D part visualizations, torque and test parameters, and inspection callouts directly onto aircraft structures and components. Adoption is constrained by data readiness, integration with MRO/MES/QMS, validation burden, device ergonomics, and export-control/IT security requirements.

Show operators only the minimum decision support they need at the point of work: a clear risk state, why it matters, and the approved next action. Do not expose raw model detail by default. This works only if thresholds, escalation rules, data quality, validation, and HMI integration are controlled, traceable, and tested in the real process.

Technician resistance to new digital tools in regulated plants is usually rational: they see risk to throughput, quality, and personal accountability. Managing it requires involving technicians early, proving stability in pilots, protecting them from blame during rollout, and integrating tools into existing systems, training, and change control rather than forcing a rapid full replacement.
