Teledyne Continental Motors Piston Engines

AD/CON/69 Incorrect Connecting Rods 1/94 DM

Applicability: Teledyne Continental Motors (TCM) O-200A, O-300A, O-300C and O-300D engines as listed by serial number in FAA Airworthiness Directive 93-11-03 (Copy attached).

Note: This Directive is only applicable to engines which were overhauled or rebuilt by TCM. This Directive is not applicable to engines overhauled in Australia, or by organisations other than TCM.

Requirement: In accordance with the procedure detailed in FAA Airworthiness Directive 93-11-03, inspect the engine for evidence of IO-360 series connecting rods being fitted.

Compliance: Effective 1 December 1993: Unless previously accomplished, engines with less than 100 hours time in service; prior to further flight.

Note: TCM and the FAA have determined; engines with incorrect con-rods fitted may fail before 100 hours time in service.

Background: This Directive requires the inspection of applicable engines to determine if the correct connecting rods were fitted by the manufacturer. The requirement follows advice of a number of O-200 and O-300 engines shipped by TCM with IO-360 series connecting rods fitted. The IO-360 connecting rod has a piston pin bushing diameter of 1.00" versus 0.923" for the 0-200 and 0-300 connecting rod.
