To provide correct information concerning fuel tank capacities, within the next 50 hours' time in service after the effective date of this AD, unless already accomplished, perform the following:
A) Remove the existing placard on the fuel selector valve and install in its place either applicable Cessna P/N 0511167-20 placard or Cessna P/N 0500246-11 placard in accordance with Cessna Service Letter SE 68-12 dated March 12, 1968, or later FAA-approved revision, or any FAA-approved equivalent placard which would show usable fuel capacity of 18 gallons left tank, 18 gallons right tank, 36 gallons both and an off position.
B) Revise the existing markings at the fuel filler necks to read: "FUEL 80/87 GRADE. TOTAL CAPACITY 19.5 GALLONS". (The operator may make and install the above markings with painted markings, using a minimum of 1/8 inch high letters.)
This amendment becomes effective August 31, 1971.
