Certificated mechanics, under their general certificate privileges, may perform 100 hour inspection of instruments.

• A. Engines
• B. Airframes
• C. Instruments
• D. Propellers

Answer: (C)

Understanding who can perform a 100-hour inspection is key. A certificated mechanic with general privileges can handle routine maintenance and inspections on components that don’t require a specialized rating. The 100-hour inspection is a recurring check used for aircraft operations, and the scope of what a general-privilege mechanic can inspect includes the aircraft’s instrument systems. Engine and propeller tasks typically require the specific engine or propeller ratings. Since instruments fall under the general maintenance area rather than a specialized area, performing a 100-hour inspection on the instruments is allowed.
