Which statement is true regarding required maintenance inspections?

1. A 50-hour inspection may be substituted for an annual inspection

2. An annual inspection may be substituted for a 100-hour inspection

3. A 100-hour inspection must always be completed

4. An annual inspection is mandatory every month

The correct answer is: An annual inspection may be substituted for a 100-hour inspection

The statement that an annual inspection may be substituted for a 100-hour inspection is accurate because of the regulations governing aircraft maintenance. Specifically, when an aircraft is required to undergo a 100-hour inspection due to being used for hire or flight instruction, a valid annual inspection can be used to satisfy that requirement. This provides flexibility in maintenance schedules and ensures that the aircraft is maintained to the standards set for annual inspections, which are typically more comprehensive. In contrast, the other options are not true. A 50-hour inspection cannot substitute for an annual inspection because they are different in scope and frequency; the annual inspection covers a wider range of checks. A 100-hour inspection must be performed for certain operations but does not apply universally and can be bypassed if the aircraft is not being operated in a capacity that requires this inspection. Lastly, saying an annual inspection is mandatory every month is inaccurate, as annual inspections are required once every 12 calendar months. Thus, the only correct assertion relates to the substitution possibility of an annual inspection for a 100-hour inspection.
