Which aircraft could exceed the 10-hour inspection interval while en route to have an inspection performed?

The correct choice indicates that both an aircraft on a progressive inspection program and an aircraft on a 100-hour inspection program could exceed the 10-hour inspection interval while en route to have an inspection performed.

In a progressive inspection program, aircraft maintenance is spread out over a series of inspections with less frequent, smaller inspections happening frequently. This allows for flexibility, enabling the aircraft to fly past the 10-hour mark while still being in compliance with maintenance regulations, as long as it is on its way to a scheduled maintenance event.

Similarly, an aircraft on a 100-hour inspection program also has situations and allowances for exceeding specific intervals; operational considerations may permit flights to exceed the regular inspection interval temporarily while en route to a maintenance facility.

Both aircraft types can, therefore, legally operate beyond the 10-hour limit, reflecting the system's recognition of operational urgency and the need for practical management of maintenance schedules. This is particularly important for aircraft that are expected to operate in commercial contexts where delays can lead to significant economic impacts.
