(The following safety article from the Wichita Aircraft Certification Office is published as received. Contact information is found at the discussion’s end.)

“The FAA has been advised that some fuel strainer assemblies may have been originally installed or are being put back into service improperly. Airplanes may have the fuel strainer assembly installed with the fuel flow arrow oriented against the fuel flow path. In this configuration, although fuel may freely flow, fuel system contaminants may not be removed from the fuel system during a normal pre-flight check of the fuel strainer. We recommend all owners and operators check the fuel flow arrow orientation on their fuel strainers at the next inspection interval to be sure the fuel flow direction arrows are oriented properly. Refer to the applicable airplane model maintenance/service manual or applicable service bulletin/letter for the proper orientation of the fuel flow direction arrow on the fuel strainer.” (For further information please contact Mr. Jeff Janusz, aerospace engineer; Wichita Aircraft Certification Office, 1801 Airport Road., Room 100, Wichita, KS. 67209 Phone 316-946-4148.)
