© AIRBUS S.A.S. 2015. ALL RIGHTS RESERVED. CONFIDENTIAL AND PROPRIETARY DOCUMENT MMEL 25-62-01 3. REASON 3.1 FACTS Note : Use colour printed document fo r better illustration visualisation. Incorrect connection of the girt (Fig 1 – item 6) on one PAX door 2 and one PAX door 4 have been observed on two different A330 aircraft prior to delivery. Examination revealed that the quick release bar (Fig 1 – item 12) was not installed into the girt (Fig 1 – item 6) of the slide raft. Refer to Figure 1 illustration applicable for slide rafts and Figure 3 for the observed incorrect installation. Further inspections at the Final Assembly Line revealed a third case of incorrect installation of the girt (Fig 2 – item 6). This last event occurred on one Emergency exit door. The girt bar (Fig 2 – item 11) was observed not fitted in to the girt (Fig 2 – item 6) of the escape slide. Refer to Figure 2 illustration applicable for escape slides. Note : Slide rafts and escape slides have two differen t system designs regarding the girt connection to the door sill. For the Slide raft, a quick release bar (Fig 1 – item 12) is fitted into the girt (Fig 1 – item 6). This quick release bar (Fig 1 – item 12) is also at tached to the girt bar (Fig 1 – item 11). Refer to the figure 1 illustration applicable for Sli de rafts. Refer also to AMM 25-62-41 PB401 for further illustrations. Whereas for the Escape slide, the girt bar (Fig 2 – it em 11) is directly fitted into the girt (Fig 2 – item 6). No additional part is used for the connection to the door. Refer to the figure 2 illustration applicable for Escape slides. Refer also to AMM 25-62-42 PB401 for further illustrations.AOT re f Fi
