How many hours may an aircraft requiring a 100-hour inspection be flown beyond the inspection requirement?

The correct answer is based on regulations governing aircraft maintenance, specifically regarding 100-hour inspections. For an aircraft that requires a 100-hour inspection, the regulations typically allow the aircraft to be flown a maximum of 10 hours beyond the inspection requirement. This provision is designed to accommodate situations where it may not be possible to perform the inspection immediately after reaching the 100-hour mark, ensuring safety while still adhering to maintenance standards.

This additional time must be used judiciously, as the aircraft is still operating beyond its inspection interval, but the allowance provides flexibility for operators. It's important to note that continuing to fly an aircraft beyond the required inspection period should be done with caution and typically only in situations where it is absolutely necessary to reach a maintenance facility.
