It is possible to have fuel accumulation inside the conduit due to wiring protection sealant in the conduit end. The absence of the ability to detect fuel leakage in the clear ice detector wiring conduit, when associated with an ignition source, could result in fire or explosion inside the tank. |\n\n![](image.001.png)  \nJames Coyne  \nDelegate of the Civil Aviation Safety Authority\n\n16 June 2008","sortOrder":0},{"sectionNumber":"AD/EMB-145/7","sectionType":"part","heading":"AD/EMB-145/7","content":"## AD/EMB-145/7","sortOrder":1},{"sectionNumber":"Ice Detector Wiring Conduit","sectionType":"part","heading":"Ice Detector Wiring Conduit","content":"## Ice Detector Wiring Conduit","sortOrder":2},{"sectionNumber":"8/2008","sectionType":"part","heading":"8/2008","content":"## 8/2008","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.
