What has replaced Annual / 100 Hr inspections for airline and corporate operators?

Progressive Inspection Programs have been adopted to enhance the efficiency and effectiveness of maintenance practices for airline and corporate operators. These programs allow for a continuous approach to inspections, breaking down the traditional Annual and 100-hour inspections into manageable, scheduled tasks that can be conducted over a specified period rather than at one time.

This methodology encourages operators to focus on specific components or systems at designated intervals, promoting a more thorough understanding of the aircraft's condition. Operators can adjust the focus based on actual risk exposure and usage patterns, which can improve safety, reliability, and operational availability. In contrast, the other options do not directly replace the inspection schedule with a systematic approach; rather, they pertain to safety assessments and management practices that do not have the same inspection frequency or detail required for airworthiness.
