Applies to All Aircraft with Continental E185, E225, 0-470, IO-470 and Lycoming O-320, 0-360, and IO-360 Engines Incorporating Superior Flow Oil Filters Installed in Accordance with Supplemental Type Certificates SE325SW, SE419SW, and SA401SW. Unless already accomplished, compliance required before further flight except that the airplane may be flown in accordance with FAR 21.197 to a base where the replacement can be made. Several failures of Superior Flow oil filter elements, P/N US5003-27 and US5003-33, have occurred during cold weather starts and run-up, resulting in loss of oil and severe engine damage. To prevent additional failures of this nature, Superior Flow filter elements P/N US5003-27 and US5003-33 must be replaced with redesignated filter elements P/N US5003-27A and US5003-33A, respectively. If these new assemblies cannot be obtained, the entire oil filter system must be removed, and replaced with one approved for the engine. (Superior Flow Service Bulletin No. 1A, dated December 7, 1964, covers this subject.)
