## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB- 135BJ airplanes. This proposed AD would require modifying the forward and aft auxiliary fuel tanks. This proposed AD results from a report of sparks due to chafing between the harnesses of the forward and aft auxiliary fuel tanks, between certain harnesses attached to the aircraft structure, or between certain harnesses attached to certain mechanical components. We are proposing this AD to prevent a potential ignition source inside a fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion.
