    DM

               Applicability: AS 350 B3 helicopters equipped with Ancillary Systems Unit (ASU) printed circuit boards (PCB) No. 2 Part Number (P/N) SE 03022 (704A47720110).

                  Requirement: 1. Inspect ASU PCB No. 2, in accordance with the instructions in Eurocopter AS 350 Service Bulletin 77.00.07 date code 00-15, to determine whether resistor R8 is installed.

2.        If the Requirement 1 inspection determines that resistor R8 is not installed, replace the PCB with a PCB that has R8 installed.

3.        ASU PCB P/N SE 03022 (704A47720110) without resistor R8 installed may not be fitted to any helicopter.

               Note: DGAC AD 2001-319-083(A) refers.

               Compliance: For Requirement 1 - Within 25 hours time in service from the effective date of this Directive.

 SCHEDULE OF AIRWORTHINESS DIRECTIVES

            Background:  This Directive requires inspection of ASU PCB No. 2 to ensure resistor R8 is installed. The absence of resistor R8 can lead to a malfunction of the electrical circuits supplying the BATT TEMP red warning light, the ENGINE CHIP amber caution light and the rotor RPM signal output to the Vehicle Engine Management Display (VEMD).
