Requirement:    Install a hinge pin stopper on the internal door of the 103VU box in accordance with the instructions given in SB A320-25-1535 or later approved EASA revision.
                Note:  EASA AD 2007-0214 refers.
Compliance:     Before 31 March 2009.
                This Amendment becomes effective on 27 September 2007.
Background:     Heat damaged and severed electrical wires have been found in several 103VU boxes.  Those electrical damages are caused by a contact between the horizontal hinge pin and adjacent electrical harness.  Investigation revealed that the pre-mod 36115 manufacturing process used to secure the pin by deforming the hinge ends, or the hinge pin ends, does not prevent the pin translatory motion.

   To avoid harness damage and subsequent failure on the associated systems, the original issue of this Directive mandated the inspection of 103 VU panel hinge pin according to Airbus All Operators Telex (AOT) 25A1440.  In service experience has shown that AOT 25A1440 inspection procedure and its associated corrective actions were not sufficient to detect and solve hinge pin migration.
   This Amendment mandates the installation of a hinge pin stopper on the internal door of the 103VU box.
   The original issue of this Directive became effective on 9 June 2005.
