Consequently, the flap track No.3 fairing was detached from its aft end, and found hanging. Investigations have shown that the detachment of the aft lower drive strut fitting from the fairing occurred due to the four bonded inserts being pulled out.This condition, if not corrected, could lead to in-flight loss of the affected aircraft parts, potentially resulting in injuries to persons on the ground.This directive mandates modification of the moveable flap track fairing No.3, both left hand and right hand sides and prohibits re-installation of unmodified units. |\n\n![](image.001.png)  \nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n12 August 2008","sortOrder":0},{"sectionNumber":"AD/A330/91","sectionType":"part","heading":"AD/A330/91","content":"## AD/A330/91","sortOrder":1},{"sectionNumber":"Wings - Movable Flap Track Fairing no 3","sectionType":"part","heading":"Wings - Movable Flap Track Fairing no 3","content":"## Wings - Movable Flap Track Fairing no 3","sortOrder":2},{"sectionNumber":"10/2008","sectionType":"part","heading":"10/2008","content":"## 10/2008","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
