What type of inspection is a hangar check typically considered?

A hangar check is typically considered a comprehensive maintenance inspection because it involves a thorough evaluation of an aircraft's systems and components within a controlled environment, such as a hangar. These inspections are intended to ensure that all aspects of the aircraft are functioning correctly and meet the necessary safety and operational standards.

During a hangar check, various systems, including avionics, engines, and mechanical components, are scrutinized in detail. This level of examination is essential for identifying any wear and tear, necessary repairs, or scheduled maintenance that needs to be performed before the aircraft is returned to service. The focus is on comprehensive inspection to maintain airworthiness and reliability throughout the aircraft's lifecycle.

In contrast, other types of inspections may not be as detailed or thorough, making the hangar check distinct in its approach to maintenance and safety assurance.
