 AD/B737/158 Amdt 1 (continued)

            Background: The original issue of this Directive required installation of components to provide shielding and separation of the fuel system wiring (that is routed to the fuel tanks) from adjacent wiring. The issue of the referenced FAA Airworthiness Directive was prompted by testing results, obtained in support of an accident investigation, and by re-examination of possible causes of a similar accident.

            This Amendment introduces an alternative method of compliance.

            The original issue of this Airworthiness Directive became effective on 9 August 2001.
