                737-30A1057, dated 6 October 2006, are acceptable for compliance with the Requirement 1; provided that the wiper motor serial number was legible for inspection purposes and the operational test specified in Step 3 in Work Packages 2 and 3 of the Accomplishment Instructions of ASB 737-30A1057, Revision 1, was completed.
                2. Rosemount Aerospace windshield wiper motors having P/N 2313M-347-3 or P/N 2313M-348-3 (P/N 2313M347-3 or P/N 2313M348-3) may not be installed on any aeroplane as a replacement spare.

             Note 4:  FAA AD 2008-24-05 Amdt 39-15745 refers.
Compliance:  For Requirement 1 - Within 60 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 15 January 2009.
Background:  This Directive requires an inspection to determine the part and serial numbers of the windshield wiper motors for the pilot's and first officer's windshields together with the accomplishing of applicable corrective actions.  This Directive results from two reports that the left and right windshield wipers stopped working in flight.  The Directive is issued to prevent failure of the windshield wipers in wet weather, which could result in decreased visibility for the flightcrew.
