Drone exam · Maintenance and airworthiness

A fleet has identical drones, but one aircraft flies three times as many hours and many more dusty construction missions. Should both aircraft receive maintenance only on the same calendar dates?

Answer

No. Use the manufacturer's instructions and the aircraft's actual hours, cycles, environment, and condition. The harder used aircraft may reach maintenance triggers earlier.

Explanation

Calendar time is only one maintenance driver. Usage and operating environment can consume component life much faster.
