2. Action in accordance with Cessna Service Bulletin MEB93-10 Revision 1. Compliance: 1. By 25 June 1995. 2. As specified in the Requirement Document with a revised effective date of 22 June 1995.

Note: If any valve fails to close during functional testing and an outside stimulus is used to close the valve, such as thumping or bumping the wing near the valve, then the valve has failed the functional test and should be removed and inspected prior to further flight.

Background: The failure to seal of a fuel inlet valve is suspected to have caused the fatal accident of an overseas Cessna 402C aircraft. Amendment 3 was raised in sequence to advise maintenance staff that Cessna MEB92-13 was being retained as the inspection document following issue of Cessna MEB 92-13 Revision 1. Also that FAA AD 93- 05-03 was an alternate means of compliance.

This amendment mandates compliance with Revision 1 of Cessna MEB 93-10.
