Which party is typically authorized to apply range markings to an instrument dial face?

• A. Certified airframe mechanic
• B. Flight crew member
• C. Aircraft painter
• D. Maintenance supervisor

Answer: (A)

Range markings on an instrument dial face are part of maintenance tasks that require proper authority and calibration expertise. A certified airframe mechanic has the training and certification to perform instrument calibration and labeling, ensuring the markings are accurate, legible, and properly documented. This responsibility goes beyond the roles of flight crew members, who operate the aircraft and rely on instruments, or aircraft painters, who focus on cosmetic work. A maintenance supervisor oversees tasks, but the actual marking is done by the authorized technician who can verify accuracy and keep records. That combination of certification, training, and traceability is why a certified airframe mechanic is the appropriate person to apply range markings.
