These carburetors are installed on, but are not limited to Cessna TR182 aircraft with Lycoming O-540-L3C5D engines.

Compliance required within 30 days after the effective date of this AD, unless previously accomplished.

To preclude failure of the engine during idle conditions, remove the carburetor from service and replace with an airworthy carburetor of the same part number with serial number DF-1-500 or subsequent. The aircraft may be flown in accordance with FAR 21.197 to a base where the modification can be performed.

This amendment becomes effective April 25, 1979.
