During installation, which person is responsible for ensuring proper markings on the instrument?

• A. The maintenance supervisor
• B. The pilot in command
• C. The aircraft owner
• D. The mechanic installing the instrument

Answer: (D)

The main idea is that the person who actually performs the installation is responsible for making sure the instrument is properly marked. When a new instrument is installed, markings such as identification of the part, installation date, calibration status, and the technician’s identity need to be present and accurate. This creates a clear, traceable record of what was installed, when, and who did it, which is essential for future maintenance and airworthiness. The pilot in command is in charge of safe operation of the aircraft, but does not perform installation markings. The aircraft owner isn’t the one physically installing or marking the instrument, and while a maintenance supervisor may oversee the work, the direct responsibility for proper markings lies with the mechanic or technician who performs the installation.
