47-47-14 REPUBLIC: (Was Service Note 4 of AD-769-2.) Applies to Model RC-3 Aircraft with Engine Serial Numbers 23001 to 24065 Inclusive.
Compliance required at each 25-hour inspection.
Drain the oil from the engine and inspect the sump oil inlet screen assembly as follows:
Insert a finger through the drain hole in the sump; locate the oil screen and with direct side pressure attempt to move the oil screen horizontally. If appreciable horizontal movement is caused by hard pressure or if the oil screen is not directly over the drain hole, the oil inlet assembly may be cracked and required replacement. The late type assembly includes a nonfloating oil screen. Until this late type float and assembly is installed fill with no more than 11 quarts of oil and mark the filler cap accordingly.
When the late type parts have been incorporated, the above inspection is no longer required and 12 quarts of oil may be placed in the sump and the filler cap should be remarked accordingly.
The above inspection should be made immediately when any unexplained oil pressure drop is apparent.
(Franklin Service Bulletin No. 58 dated June 11, 1947, covers this same subject.)
