This Directive results from a fire in the forward lower lobe cargo compartment found shortly after aeroplane arrival. The Directive is issued to detect and correct damage to wires in the forward and aft lower lobe cargo compartments, which could result in a potential short circuit and consequent fire in the forward and aft lower lobe cargo compartments. |\n| ----------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n\n![](image.001.png)  \nCharles Lenarcic  \nDelegate of the Civil Aviation Safety Authority\n\n7 September 2007","sortOrder":0},{"sectionNumber":"AD/B767/231","sectionType":"part","heading":"AD/B767/231","content":"## AD/B767/231","sortOrder":1},{"sectionNumber":"Inspections of Wire Bundles","sectionType":"part","heading":"Inspections of Wire Bundles","content":"## Inspections of Wire Bundles","sortOrder":2},{"sectionNumber":"11/2007","sectionType":"part","heading":"11/2007","content":"## 11/2007","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
