This chafing could lead to fuel leaking into the cockpit and fire in the cockpit if wiring arcs through the fuel line. |\n| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |\n\n![](image.001.png)  \nJames Coyne  \nDelegate of the Civil Aviation Safety Authority\n\n17 July 2009","sortOrder":0},{"sectionNumber":"AD/BEECH 36/53","sectionType":"part","heading":"AD/BEECH 36/53","content":"## AD/BEECH 36/53","sortOrder":1},{"sectionNumber":"Chafing of Wire Harness/Connectorand Fue","sectionType":"part","heading":"Chafing of Wire Harness/Connectorand Fuel Line","content":"## Chafing of Wire Harness/Connector  \nand Fuel Line","sortOrder":2},{"sectionNumber":"9/2009 DM","sectionType":"part","heading":"9/2009 DM","content":"## 9/2009 DM","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
