Applicability

TypeManufacturerModelDetails
aircraft Sky Enterprises, Inc. RC-3 Airworthiness Directives; Republic Model RC-3 Aircraft

Unsafe Condition

The oil screen assembly may be cracked, causing appreciable horizontal movement when subjected to direct side pressure, which could lead to oil pressure drop.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Drain the engine oil, inspect the sump oil inlet screen assembly by applying direct side pressure to check for horizontal movement, and replace the assembly if cracks are found. Install the late type nonfloating oil screen assembly to eliminate the inspection requirement and allow 12 quarts of oil, updating the filler cap marking accordingly.

REGULATORY TEXT:   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.)
