together with Modification Instructions A, M through O, and P through S of Gulfstream IV ASC 327B.

 Gulfstream (Grumman) G1159 and G-IV Series Aeroplanes

 AD/G1159/42 (continued)

c.         If the aeroplane has Gulfstream IV ASC 327A installed, ensure that wire P9052C22 is rerouted and reconnected in accordance with Gulfstream GIV Customer Bulletin 102B and Figure 7 of Gulfstream IV ASC 327B.

            Note 2: Page 1 of Gulfstream IV ASC 327B incorrectly refers to Figure 5; Figure 7 is the correct figure.

            Note 3: FAA AD 2004-08-08 Amdt 39-13577 refers.

            Compliance: For Requirements 1 and 2 - Within 12 months after the effective date of this Directive.

            This Airworthiness Directive becomes effective on 5 August 2004.

            Background: This Directive requires either the installation of an additional indicator located on the pilot's instrument panel or the use of the EICAS (Engine Instruments/Caution Advisory System) to the flight crew that the aeroplane main batteries are powering the direct current (DC) essential bus. This action is necessary to ensure that the flight crew is aware that an electrical system failure has occurred and that the aeroplane main batteries are powering the essential DC bus. If the flight crew is unaware of this situation, action to stop depletion of the aeroplane batteries will not be taken, and critical communications and navigation equipment could fail.
