- Internet/Intranet. Reason: During a production test run , a non - compliance of the installed cylinder head ass embl y of cylinder no. 2 and 3 (2/3) w as detected , which may result in a latent defect on a limited number of engines. The affected cylinder heads may not have been manufactured in accordance with the specification. This condition, if not detected and corrected, could lead to an oil leak in the intake cha nnel in the area of the valve guide. The affected non

- conforming cylinder heads may have small machined through holes, which can increase the oil consumption an d can lead to oil starvation, possibly resulting in engine stoppage or in

- flight engine shutdown and forced landing, with consequent risk of damage to the aeroplane and injury to occupants. For the reasons described above, this AD requires inspect ion of the affected cylinder head ass emblies and, depending on findings, replacement of the cylinder head assembly. This AD also prohibits installation of an affected engine on an aeroplane , unless the affected cylinder head ass embly of that engine ha s passed the inspection as required by this AD.
Effective Date: 08 March 2013 Required A ction(s) and Compliance Time(s) : Required as indicated, unless accomplished previously: (1) W ithin 5 flight hours or 20 days, whichever occurs first after the effective date of this AD, inspect the cylinder head ass embl y of cylinder no. 2 and 3 (2/3) in accordance wi th the instructions of Section 3 of BRP
