According to 14 CFR Part 43, the progressive inspection program is designed to divide the maintenance activities of an aircraft into smaller, periodic inspections. These inspections are aimed at ensuring the ongoing airworthiness of the aircraft. The inspections involved in the progressive inspection program include the Phase Inspection, the Annual Inspection, and the Progressive Inspection.
However, the 100-Hour Inspection is not part of the progressive inspection program. It is a separate requirement that applies to certain aircraft engaged in commercial or rental operations.
