first after the effective date of this Directive.

             For Requirement 4 - After 7 February 2009.
             This Airworthiness Directive becomes effective on 7 February 2008.
Background:  The engine manufacturer has advised that a short circuit of some tantalum capacitors inside certain EEC units may lead to an in-flight shutdown on one of the two engines.  Investigations have indicated that the tantalum capacitors may have become embrittled during acceptance tests performed by the supplier and are liable to short circuit.
             This Directive requires the identification and modification of EEC units that have the tantalum capacitors installed that could have become brittle during their acceptance test.
