             Later revisions of the SBs listed in Requirement 1, approved by the United States Federal Aviation Administration (FAA) as an Alternate Method of Compliance (AMOC) to FAA AD 2008-05-01, are considered acceptable for compliance with the equivalent requirements of this Directive.
             Note 2:  FAA AD 2008-05-01 Amdt 39-15395 refers.
Compliance:  For Requirement 1 - Within 2,200 hours time in service after the effective date of this Directive, but not to exceed 24 months after the effective date of this Directive.
             For Requirement 2 - Before further operation of the engine.
             This Airworthiness Directive becomes effective on 10 April 2008.
Background:  The FAA has advised of the discovery of miswired FMU overspeed solenoids in the field which could prevent the engine from failing to shutdown during an overspeed and which may lead to uncontained engine failure.  This Directive requires a one time test of the FMU for a miswired (reversed polarity) condition of the input wires to the overspeed solenoid.
