AD 2007-04-19R1 Amendment 39-15005 dated 23 March 2007 refers.
Compliance:     1. Before cylinder assemblies reach 150 hours total time in service (TTIS).

             Note 3:  For aircraft with engine cylinder assemblies that have greater than 150 hours TTIS, special flight permits may be issued to ferry the aircraft to a maintenance base.

                2. After the effective date of this AD.
             This Amendment becomes effective on 7 June 2007.
Background:  This AD results from discovery of nine separated SAP cylinder assemblies installed in TCM 470, 520, and 550 series reciprocating engines and one separated SAP cylinder assembly installed in Lycoming Engines 320, 360, and 540 series engines.  CASA is issuing this AD to prevent cylinder separation that can lead to engine failure, a possible engine compartment fire, and damage to the aeroplane.

             The current amendment corrects manufacturing date range based on Revision 1 of the FAA AD 2007-04-19 dated 23 March 2007 and makes a few editorial changes.

             Amendment 1 of this AD made reference to the cylinders assemblies detailed in the manufacturer's service bulletin and became effective on 5 March 2007.

             The original issue of this AD became effective on 2 March 2007.
