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

• A. A 100-hour inspection is for all aircraft, an annual is for those used for hire
• B. A 100-hour inspection is only for aircraft used for hire, an annual is for all aircraft
• C. There is no difference; they are interchangeable
• D. Only 100-hour inspections require detailed report submissions

Answer: (B)

The distinction between a 100-hour inspection and an annual inspection is rooted in the operational context and regulatory requirements governing aircraft maintenance. A 100-hour inspection is specifically mandated for aircraft that are used for hire, such as charter services or flight schools. This type of inspection ensures that the aircraft remains in a safe and airworthy condition between longer intervals. On the other hand, an annual inspection is required for all aircraft, regardless of their commercial or private use, and must be performed every 12 calendar months. While the 100-hour inspection focuses on the maintenance needs of aircraft that are regularly used for hire, the annual inspection provides a comprehensive assessment applicable to all aircraft types. Understanding this difference is crucial for aviation maintenance professionals, as it informs how they schedule maintenance activities and comply with Federal Aviation Administration (FAA) regulations. The annual inspection serves a broader range of aircraft, ensuring safety across both private and commercial aviation sectors.
