Which inspection is a thorough inspection of the entire aircraft?

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

Answer: (B)

A thorough inspection of the entire aircraft is performed by the Major ISO inspection. This level is designed to inspect all major systems and structures of the airplane, not just a subset of components. It typically includes comprehensive checks of the airframe, powerplant interfaces, flight controls, landing gear, hydraulics, electrical and avionics, and related systems. It may involve more extensive procedures, possible disassembly, and non-destructive testing as required, with documentation to verify compliance with maintenance data. It's scheduled at defined in-service intervals to ensure the aircraft remains airworthy. The other options don’t aim for a full aircraft-wide review. A minimum ISO inspection focuses on essential items and basic condition checks rather than a complete, depth-heavy survey. Home Station Check is a routine base-level maintenance step that looks at common items between larger checks but still isn’t the depth of a Major ISO. Calendar Inspections are time-based and may vary in scope, but they’re not defined as the full-aircraft, all-systems inspection that Major ISO provides.
