Which are the two types of inspection used in the Progressive Inspection Program?

In a Progressive Inspection Program, the two types of inspections recognized are routine and detailed inspections. Routine inspections are typically more frequent and less intensive, focusing on visual checks and general observations of the aircraft and its components to ensure they are functioning correctly. These inspections help in maintaining the operational safety and reliability of the aircraft by identifying any obvious issues before they escalate.

On the other hand, detailed inspections are more exhaustive and thorough, often involving disassembly or closer examination of components. This type of inspection may be scheduled at specific intervals or after particular flight cycles to ensure that even hidden or subtle defects are identified and addressed.

This combination of routine and detailed inspections allows for a comprehensive approach to aircraft maintenance, ensuring that potential problems are caught early and that the aircraft remains in a safe, operable condition.
