The term "dock" refers to inspections performed for what purpose?

• A. Major inspections
• B. Preflight readiness only
• C. Annual cabin checks
• D. Ground handling only

Answer: (A)

Dock inspections are the thorough, major maintenance checks performed when an aircraft is in the maintenance dock to verify overall airworthiness. They go beyond everyday tasks like preflight readiness or routine interior checks, and they aren’t limited to just moving the aircraft on the ground. During a dock, technicians inspect and service major systems, inspect structural components, perform disassembly as needed, and confirm everything is serviceable and safe for return to flying status. The purpose is to validate that the aircraft meets all required standards after maintenance or a certain number of flight hours, not just to handle short-term operational concerns.
