Commercial Pilot License (CPL) Practice Exam

The correct answer states that the maximum flying time an aircraft can exceed the 100-hour inspection limit before it must be inspected is 10 hours. This is in accordance with regulations that provide a grace period for aircraft operation beyond the established maintenance intervals, acknowledging that operational needs may occasionally require slight extensions.

In this case, if an aircraft is flown beyond the 100-hour mark yet within the allowable 10-hour window, it is legal to do so, but the aircraft must still be inspected immediately after that additional flying time. Pilots and operators must remain diligent about maintenance schedules to ensure safety and comply with aviation regulations.

The notion of exceeding this limit without restriction would lead to safety concerns and regulatory violations. Therefore, the regulation does not permit unlimited flying time beyond the inspection limit, ensuring that aircraft remain in a safe operational condition. Similarly, the lesser durations presented as potential answers do not align with established regulatory grace periods for inspections.
