3. REASON 

3.1 FACTS 

Note : Use colour printed document for 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 into 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 different 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 attached to the girt bar (Fig 1 – item 11). 

Refer to the figure 1 illustration applicable for Slide rafts. Refer also to AMM 25-62-41 PB401 for 

further illustrations. 

Whereas for the Escape slide, the girt bar (Fig 2 – item 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.
