             Definition of a Replacement Cylinder Assembly

                For the purpose of this AD, a replacement cylinder assembly is defined as follows:

                  i. A serviceable cylinder assembly made by Lycoming Engines.

                  ii. A serviceable FAA-approved, Parts Manufacturer Approval cylinder assembly from another manufacturer.

                  iii. A serviceable ECi cylinder assembly, P/N AEL65102 series, "Titan", having casting P/N AEL85099.

                  iv. A serviceable ECi cylinder assembly, P/N AEL65102 series "Classic cast" having casting head markings EC 65099-REV-1 that has a SN 9880 or higher. (SN may have an "L" prefix for a long reach spark plug).

                3. Do not install any ECi cylinder assembly, P/N AEL65102, having casting head markings EC 65099-REV-1, that has a SN 1 through 9879 onto any engine. (SN may have an "L" prefix for a long reach spark plug).
             Note 2:  FAA AD 2006-12-07 amendment 39-14632 refers. FAA AD 2006-12-07 supersedes AD 2005-26-10.

             Note 3:  ECi Mandatory Service Bulletin 05-8 Revision 2 dated 28 February 2006 pertains to the subject of this AD.
Compliance:     1. Within 10 hours after the effective date of this AD, unless previously accomplished.

                2. If the cylinder assembly has fewer than 800 operating hours- in-service (HIS) on the effective date of this AD, replace the cylinder assembly at no later than 800 operating HIS.  No action is required until the operating HIS reaches 800 hours.

                If the cylinder assembly has 800 operating HIS or more on the effective date of this AD, replace the cylinder assembly within 60 operating HIS after the effective date of this AD.

                3. After the effective date of this AD.
             This Amendment becomes effective on 3 August 2006.

Background:  The FAA has approximately 30 reports of failure of the subject cylinder assemblies marketed by ECi.  The requirements of this AD are to prevent loss of engine power due to cracks in the cylinder assemblies and possible engine failure caused by separation of a cylinder head.

             Amendment 2 deletes reference to FAA AD 2005-26-10 which is now superseded by FAA AD 2006-12-07.  The current amendment also corrects applicability errors and makes reference to the latest revision of ECi Service Bulletin.

             Amendment 1 of this AD corrected a typographical error noted in the original issue of the AD and became effective on 13 April 2006.

             The original issue of the AD became effective on 16 February 2006.
