Analysis has shown that the slide may inflate too fast compared to the associated door release. If there is a delay during the opening of the door, the inflatable slide may exercise a pressure on this not yet opened door, which can result in damage to the inflatable slide. A slide not inflated correctly may disrupt passenger emergency evacuation. |\n\n![](image.001.png)  \nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n16 April 2008","sortOrder":0},{"sectionNumber":"AD/A320/218","sectionType":"part","heading":"AD/A320/218","content":"## AD/A320/218","sortOrder":1},{"sectionNumber":"Escape Slide Failure at Doors 2 and 3","sectionType":"part","heading":"Escape Slide Failure at Doors 2 and 3","content":"## Escape Slide Failure at Doors 2 and 3","sortOrder":2},{"sectionNumber":"6/2008","sectionType":"part","heading":"6/2008","content":"## 6/2008","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
