## Abstract

The FAA is superseding an existing airworthiness directive (AD) for Lycoming Engines (formerly Textron Lycoming) models 320, 360, and 540 series, "Parallel Valve" reciprocating engines, with certain Engine Components Inc. (ECi) cylinder assemblies, part number (P/N) AEL65102 series "Classic Cast", installed. That AD currently requires replacing these ECi cylinder assemblies. This AD requires the same actions, but replaces the "Engine Models" Table 1 and "Engines Installed On, But Not Limited To" Table 2 with corrected tables. Also, this AD corrects the casting part number. This AD results from reports of applicability errors found in AD 2005-26-10. We are issuing this AD to prevent loss of engine power due to cracks in the cylinder assemblies and possible engine failure caused by separation of a cylinder head.
