Hourly Post Flight (HPO) is designed to do what?

• A. Ensure airworthiness of the aircraft in depth flying hours
• B. Monitor crew rest hours
• C. Schedule fuel deliveries
• D. Inspect for cabin cleanliness

Answer: (A)

Hourly Post Flight focuses on keeping the aircraft airworthy as its time in service increases. After each flight, maintenance personnel perform targeted checks tied to flight hours to confirm critical systems are functioning, look for wear or leaks, verify fluid levels and lubrication, and note any abnormal conditions. This process catches potential issues early and helps trigger the next maintenance or repair before the next flight, ensuring safety and regulatory compliance. It isn’t about tracking crew rest, arranging fuel deliveries, or inspecting cabin cleanliness, which fall outside maintaining airworthiness.
