How often should a 100-hour inspection be performed on certain aircraft?

The correct answer is that a 100-hour inspection should be performed after every 100 hours of operation. This type of inspection is mandated by aviation regulations for certain aircraft, specifically those that are used for hire or flight instruction. The purpose of this inspection is to ensure that the aircraft is in a condition for safe operation and to identify any potential issues before they compromise safety.

Conducting the inspection every 100 hours ensures that maintenance is proactive rather than reactive, minimizing the likelihood of mechanical failures during operation. This routine check includes a thorough examination of various aircraft systems and components, ensuring compliance with safety standards and longevity of the aircraft. By adhering to this schedule, operators help maintain airworthiness and ensure passenger safety.
