| 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. |
