## The airworthiness directive

74-18-07 TELEDYNE CONTINENTAL MOTORS: Amendment 39-1933. Applies to the following Teledyne Continental Model Engines: IO-360-A - Engine serial numbers 20080-R and 20084-R IO-360-C - Engine serial numbers 350015, 350017, 350021, 60228-R, 60229-R, 900308 and 900352. IO-360-D - Engine serial numbers 351048, 351055, 351060, 351075, 351076, 351077, 351080, and 351081. IO-360-H - Engine serial numbers 353124 through 353134. TSIO-360-A - Engine serial numbers 301001, and 301002. TSIO-360-C - Engine serial numbers 300162 and 300170. Compliance is required within the next 25 hours time in service after the effective date of this AD, unless already accomplished. To prevent cylinder failure, inspect each cylinder for the assembly date stamp located on the machined surface between the Rocker Box covers. All cylinders date stamped 7-73, 8-73, 9-73, 10-73, and 11-73 must be removed and replaced with airworthy cylinders prior to further flight. This supersedes Amendment39-1780 (39 F.R. 4075) AD 74-3-5. This Amendment becomes effective August 28, 1974.
