What kind of maintenance tasks are allowed for type rated pilots?

Type-rated pilots are allowed to perform certain maintenance tasks that are straightforward and do not require specialized technical expertise or extensive training. Among the options provided, the replacement of tyres and brake pads is a task that falls within the realm of general maintenance that a type-rated pilot can handle.

This is because such tasks are typically considered routine and not complex. They do not involve intricate systems or require in-depth knowledge of aircraft maintenance protocols. Tyres and brake pads can be seen as consumable parts that contribute directly to aircraft safety and performance, and thus, airlines often allow pilots to oversee their replacement under specific conditions.

Routine maintenance tasks, such as these, focus on ensuring that the aircraft remains in a safe and serviceable condition without altering the aircraft's critical systems. In contrast, tasks like complicated electrical system repairs or deep structural inspections require specialized knowledge and skills that go beyond the scope of a type-rated pilot's training. Engine diagnostics also involve complex understanding and training to assess potential issues accurately. Hence, option B aligns with the understanding of maintenance skills allowed for type-rated pilots.
