 AD/SD3-60/62 Amdt 1 (continued)

           The original issue of this Directive introduced a modification to the CWP, which provided a new annunciator light to alert the pilot that the intake anti- icing vanes have not been deployed, when other anti- icing systems have been selected. The Directive also ensured that the relevant AFM 'P' amendment is embodied.

           This Amendment introduces a revised SB which corrects wiring anomalies contained in the original SB and requires reworking of installations completed in accordance with the original SB.

           The original issue of this Airworthiness Directive became effective on 5 September 2002.
