FAA Ground School Practice Test

When was the 100-hour inspection actually performed if it was due at 3302.5 hours but done at 3309.5 hours?

1. 3302.5 hours

2. 3309.5 hours

3. 3400 hours

4. 3402.5 hours

The correct answer is: 3402.5 hours

The 100-hour inspection is a crucial maintenance requirement for certain aircraft that mandates it to be performed after every 100 hours of operation. The given scenario indicates that the inspection was due at 3302.5 hours but was only completed at 3309.5 hours. To determine when the 100-hour inspection was performed in relation to the operational hours, it is vital to recognize that the inspection is required at or before the 100-hour mark from the last inspection. Conducting the inspection at 3309.5 hours means that it took place after the 3302.5 hours due point. Considering the context, if the inspection was overdue, the latest value would indicate when it was actually executed. The significance of the hours talks about compliance; therefore, stating that the inspection was not just expected at 3302.5 hours, but actually completed at 3309.5 hours best represents the true moment the inspection took place. The option that states 3402.5 hours does not accurately reflect when the inspection was performed considering the due time and execution time; this number goes beyond the hours indicated in the scenario. Thus, identifying the exact moment of service in the logbook should reflect the increased hours due to operational
