At what level do apprentices typically conduct maintenance activities?

Apprentices typically conduct maintenance activities under supervision because they are still in the learning phase of their training. This level of oversight ensures that they are guided by experienced personnel who can provide instruction, answer questions, and correct any mistakes in real time. This environment is crucial for their development as it allows them to apply theoretical knowledge in practical scenarios while ensuring safety and compliance with aviation standards. Supervision also enables apprentices to gain confidence and improve their skills progressively as they prepare for independent work in the future.
