Requirement:

Unless previously accomplished, install a bonding jumper between the pilot valve line tube and the pressure refuelling system tube, after removing ventral fuel tank access panel 196FR, as described in the Embraer Service Bulletin 145-28-0026, original issue, or further revisions approved by the Brazilian Agência Nacional de Aviação Civil (ANAC).

Note: ANAC AD 2006-12-01 refers.

Compliance:

Within the next 10,000 hours time in service (TIS) for aircraft with less than 5,000 hours TIS, or within the next 5,000 hours TIS for aircraft with more than 5,000 hours, TIS after 4 January 2007 (the effective date ANAC AD 2006-12-01).

This Airworthiness Directive becomes effective on 31 July 2008.

\n```\n\n| Background: | The ANAC has advised that the refuelling line inside the ventral fuel tank on the Embraer EMB-145XR aircraft model is not protected in accordance with SFAR-88 requirements. This Directive corrects that anomaly by the installation of a bonding jumper between the pilot valve line tube and the pressure refuelling system tube. |\n| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |\n\n![](image.001.png) \nJames Coyne \nDelegate of the Civil Aviation Safety Authority\n\n16 June 2008","sortOrder":0},{"sectionNumber":"AD/EMB-145/9","sectionType":"part","heading":"AD/EMB-145/9","content":"## AD/EMB-145/9","sortOrder":1},{"sectionNumber":"Ventral Fuel Tank Refuelling Line","sectionType":"part","heading":"Ventral Fuel Tank Refuelling Line","content":"## Ventral Fuel Tank Refuelling Line","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.
