1) Visually inspect the placarding adjacent to the fuel filler openings, to verify that these markings agree with the actual fuel tank capacity; and
2) Visually inspect the placarding adjacent to the fuel tank selector valve, and fuel gauge markings to verify that these markings agree with the usable fuel for the fuel tanks installed.
C) Paragraph A and B of this AD may be accomplished by the holder of at least a private pilot certificate issued under Part 61 of the Federal Aviation Regulations on any airplane owned or operated by that person provided the airplane is not used in air carrier service.
