Requirement:        1. Review the aircraft's maintenance records to determine whether those records show compliance with:
                           1. The United States of America Federal Aviation Administration (FAA) AD 78-26-12, as in force from time to time; or
                           2. CASA AD/CESSNA 210/35, as in force on the day prior to its cancellation.
                Note 1:  This determination may be accomplished and certified for by the registered operator, provided that they hold at least a private pilot's licence.
                Note 2:  The words "as in force from time to time" require compliance with the most recent version of the referenced document.
                   2.         For aircraft where the aircraft's maintenance records do not show compliance with either Requirement 1.a. or 1.b. - Carry out the actions detailed in FAA AD 78-26-12, as in force from time to time.
                Note 3:  For aircraft where the aircraft's maintenance records show compliance with Requirement 1.a. or 1.b. - no further action is required.
                Note 4:  Cessna Service Letter SE78-69 relates to the subject of this AD.
Compliance:     For Requirement 1 - Within 28 days after the commencement date of this AD.
                For Requirement 2 - Before further flight.
                Note 5:  The aircraft may be flown to a location where this inspection may be accomplished, provided the pilot visually verifies through the fuel filler neck that adequate fuel is available to complete the flight.

Commencement:  This AD commences on 3 September 2021.
Background:    The possibility exists that one or both fuel quantity transmitters, due to excessive friction at the transmitter float arm pivot, could cause incorrect fuel quantity indications.
               CASA has previously addressed the potential unsafe condition through AD/CESSNA 210/35 - Fuel Quantity Transmitter - Inspection and Replacement.  AD/CESSNA
