The source of the overload was identified as a partial incompatibility of new timed relays P/N TDH-8070-1001P and/or T412-2006 (identified as K8651 and K8652) with the actual configuration of the windshield wiper electrical system.   Agusta A119 Series Helicopters   AD/A119/5 (continued)   As 109E and A119 helicopters are equipped with the same windshield wiper electrical system overheating could also occur on A119 helicopters. This Directive requires initial deactivation of the wiper system followed by modification of the system to eliminate the overheating.   Eugene Paul Holzapfel Delegate of the Civil Aviation Safety Authority 19 June 2002                               The above AD is notified in the Commonwealth of Australia Gazette on 21 June 2002.
