## Abstract

The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain EMBRAER Model EMB-145, -145ER, - 145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The original NPRM would have required replacing the electrical bonding clamps inside the fuel tanks and adjacent areas. The original NPRM resulted from a report of the failure of a fitting clamp of an electrical bonding cable for the fuel tubing. This action revises the original NPRM by adding airplanes to the applicability. We are proposing this supplemental NPRM 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.
