What type of inspection is considered for the overhaul of a system or component of an aircraft on a progressive inspection program?

In the context of a progressive inspection program, a detailed inspection is specifically tailored to meticulously examine systems or components for any signs of wear, damage, or malfunction prior to overhaul. This type of inspection is methodical and comprehensive, ensuring that every aspect of the aircraft component is evaluated according to stringent standards.

Detailed inspections are critical as they not only serve to identify potential issues but also help to establish maintenance schedules and requirements based on the condition of the components observed. They are essential for compliance with safety regulations and to maintain airworthiness, providing extensive documentation that may be required for regulatory purposes.

Other types of inspections, such as routine, component segment, and visual inspections, serve different roles within an overall maintenance program. Routine inspections are typically less thorough and focus on general serviceability, while component segment inspections look at specific assemblies or parts within a system rather than providing an exhaustive assessment of the entire component. Visual inspections, on the other hand, are surface-level checks that may not detect internal or subtle issues. Thus, while all inspection types have value, a detailed inspection is uniquely suited for the thorough assessment needed during an overhaul.
