Certificated mechanics with an airframe rating may perform a minor repair to which instrument, provided they have the necessary equipment?

• A. Attitude indicator
• B. Airspeed indicator
• C. Altimeter
• D. Gyroscope

Answer: (B)

Airframe-rated certificated mechanics can perform minor repairs on instruments that don’t require calibration, alignment, or specialized testing. The airspeed indicator fits this because it’s a simple pitot-static instrument whose repair can involve cleaning, replacing a casing or linkage, and doing basic leak checks or functional tests with standard equipment. In contrast, attitude indicators, altimeters, and gyroscopes rely on precise gyroscopic balance and calibration, requiring specialized repair facilities and procedures. So, the instrument eligible for a minor repair by these mechanics, with the right tools, is the airspeed indicator.
