Which inspection concept is used for the Hourly postflight inspection?

The Hourly postflight inspection is an inspection concept that is based on a periodic schedule. The periodic inspection concept involves routine assessments of aircraft at defined intervals, ensuring that systems and components are functioning correctly and safely after specific usage milestones.

The Hourly postflight inspection is designed to be conducted after every flight and is crucial for identifying any immediate issues that may have arisen during the flight. This inspection allows for timely maintenance and is an example of a routine approach that fits within the broader context of ensuring continuous airworthiness and safety of the aircraft.

Other concepts such as phased, isochronal, and thruflight employ different frameworks and intervals for inspections. Phased inspections are based on hours, days, or cycles and involve inspecting specific systems over specified periods rather than after every flight. Isochronal inspections follow a schedule that is based on fixed timeframes, regardless of actual usage. Thruflight inspections are specifically conducted between flights and focus primarily on checkouts of critical systems and safety checks prior to the next flight.

Thus, the nature of the Hourly postflight inspection aligns it closely with periodic inspections, emphasizing the careful monitoring of aircraft status in a regular and systematic manner.
