             Later revisions of the above SIL, approved by the FAA as an Alternate Method of Compliance (AMOC) to FAA AD 2006-04-04, are considered acceptable for compliance with the equivalent Requirements of this Directive.
             Note:  FAA AD 2006-04-04 Amdt 39-14485 refers.
Compliance:  For Requirement 1 - Within six months after the effective date of this Directive.
             For Requirement 2 - As of the effective date of this Directive.
             This Airworthiness Directive becomes effective on 11 May 2006.
