High coordination with MCC/operations
Shorter maintenance windows
Frequent troubleshooting

Base Maintenance

Planned hangar maintenance with deeper access, longer work packages and larger multidisciplinary teams. Work may include scheduled checks, structural inspections, modifications, cabin work and extensive component removal/installation.

Longer planned maintenance inputs
Deeper disassembly and access
Larger work packages
Greater exposure to structures and modifications

Exact definitions and permitted task scope depend on the approved maintenance organization and regulatory framework.
