This AD becomes effective 14 Aug 08.  This AD applies to fuel injected recriprocating engines manufactured by Lycoming Engines that incorporate externally mounted fuel injection lines (engines with an "I" in the prefix of the engine model designation) as listed in the following Table I:  See AD for effected models.  This AD results from Lycoming Engines revising the Mandatory Service Bulletin to add new engine models requiring inspection, and from the need to clarify a repetitive inspection compliance time.  This AD is being issued to prevent failure of the fuel injector fuel lines that would allow fuel to spray into the engine compartment, resulting in an engine fire.  Compliance is mandatory.
