Introduction: The purpose of this Special Airworthiness Information Bulletin (SAIB) is to alert owners/operators of American General (Gulfstream/Grumman American) AA-5, AA-5A and AA-5B models of a situation that may exist on their airplanes. This condition may result in the in-flight loss of all engine oil and/or some loss of fuel into the cabin area. This information is advisory in nature and not mandated by regulation. Background: There have been reports of the in-flight loss of all engi ne oil and/or some loss of fuel into the cabin area. The subject aircraft have rigid aluminum fuel and oil lines that feed to each respective pressure gauge. These lines were originally wrapped with a foam protective tape in the area forward of each pressure gauge. This foam tape has deteriorated with age and in some cases allowed contact between the defrost hose and the pressure line. Again, because of deterioration with age and probable relative motion between the two lines, steel wire reinforcing in the defrost hose can make c ontact with the pressure line, setting up dissimilar metal corrosion causing subsequent sudden failure of the pressure line. Each pressure line has a restrictor fitting on the engine and carburetor to prevent rapid loss of e ngine fluids in case of a line failure; however, some reports indicate that all engine oil has been lost in just a few minutes even with the restrictor in place. Note: The AG-5B aircraft do not have pressure lines in th e cabin and, therefore, are not subject to this recommendation. Recommendation: Based on currently available information, the F AA is only recommending the following actions; however, the FAA will continue this investigation. Issuan ce of an Airworthiness Directive may be found to be warranted based on analysis of new information. The FAA recommends that the inspection and repair, if necessary, specified in Fl etchAir, Inc. Critical Service Bulletin, SB 188, dated December 15, 1999, be accomplished at the next scheduled inspection and thereafter, at each annual inspection. Copies of FletchAir, Inc SB 188 may be obtained by calling the FletchAir, Inc. Parts Department at (713) 641-2023 or by mail at: FletchAir, Inc., 9000 Randolph Street, Houston, TX 77061.
