The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-145LR, -145XR, and -145MP airplanes; and Model EMB-135BJ and -135LR airplanes. This AD requires replacing the electrical bonding clamps inside the fuel tanks and adjacent areas. This AD results from a report of the failure of a fitting clamp of an electrical bonding cable for the fuel tubing. We are issuing this AD to prevent loss of bonding protection in the interior of the fuel tanks or adjacent areas, and a consequent potential source of ignition in a fuel tank and possible fire or explosion.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the time specified in paragraph (f)(1) or (f)(2) of this AD, as applicable: Replace the electrical bonding clamps having part numbers AN735D6 and AN735D4 inside the forward fuel tank or the ventral, wing stub, and wing fuel tanks, and adjacent areas, as applicable; by accomplishing all actions specified in the Accomplishment Instructions of the applicable service bulletin identified in Table 2 of this AD.
