Which inspection type conducts a thorough check of the entire aircraft?

• A. Min ISO inspection
• B. Major ISO inspection
• C. Home Station Check
• D. Calendar Inspections

Answer: (B)

The main idea here is the level of scope and depth in an inspection. A Major inspection is the one designed to examine the entire aircraft in detail—airframe, powerplant, systems, wiring, and components—often requiring more extensive disassembly, testing, and verification against maintenance data, service bulletins, and airworthiness directives. This level is scheduled less frequently but is intended to confirm the airplane’s airworthiness across all subsystems, not just surface or critical areas. In contrast, other options are more limited in scope or more about timing than a full, in-depth check of every part. A Home Station Check is done at the base and can be thorough, but it’s not necessarily as comprehensive as a Major inspection; calendar-based inspections are driven by time, not by the complete condition of all systems; and a minimal or minor check would not cover the entire aircraft as deeply.
