    What is the difference between a 100-hour inspection and an annual inspection?

    When navigating the world of aviation maintenance and inspection, two key types of inspections often come to the forefront – the 100-hour inspection and the annual inspection. While they might sound similar, each serves distinct purposes and are governed by different rules.

    A 100-hour inspection, as the name suggests, is conducted every 100 hours of service. This type of inspection is mandatory for aircraft that are used for hire. For example, if the aircraft is rented out or used for flight instruction, 100-hour inspections are a necessity to maintain its airworthiness. This inspection is a comprehensive check that covers the entire aircraft, including electronic equipment and the radio, including its internal systems and external structure, to ensure it’s operating safely and efficiently.

    On the other hand, an annual inspection is mandatory for all civil aircraft, regardless of their usage. Every 12 calendar months, these aircraft must undergo an annual inspection. Similar to the 100-hour inspection, it is a detailed check-up of the aircraft. However, it’s important to note that only an FAA-certified Inspector with an Inspection Authorization (IA) can conduct an annual inspection.

    The primary difference between the two lies in their intended usage and who can perform them. While any FAA-certified Aircraft Maintenance Technician (AMT) or an IA ( Inspection authorized aircraft mechanic) can carry out a 100-hour inspection, only an IA can conduct the annual inspection. Despite the differences, both are fundamental in ensuring the safety and performance of an aircraft.

    How many phases are typically in a progressive inspection?

    The exact number of phases in a Progressive Inspection can vary based on the aircraft model, its use, and the specific plan established by the aircraft owner or operator in conjunction with a Federal Aviation Administration (FAA) authorized inspector. However, typically a progressive inspection plan is divided into four to six phases or every 25-50 flight hours. Each phase concentrates on a specific area or system of the aircraft, allowing for a detailed and thorough inspection.

    For example, phase one might focus on the aircraft’s engines and propellers, phase two could center around the electrical systems, phase three might delve into the landing gear and brakes, and so forth. Once all phases are complete, the cycle restarts, ensuring a continuous, thorough, and comprehensive inspection of the aircraft.

    Remember, a Progressive Inspection program must meet FAA standards and be approved by the FAA before implementation. The inspection cycle must be completed within a 12-month period, and each phase must be executed by a certified mechanic or inspection authority. This way, aircraft operators can maintain the highest levels of safety and efficiency for their aircraft at all times.
