## Abstract

The FAA is adopting a new airworthiness directive (AD) for all EMBRAER Model EMB-135 airplanes; and Model EMB-145, -145ER, -145MR, - 145LR, -145XR, -145MP, and -145EP airplanes. This AD requires repetitive inspections of the pitot static heating relay K0057 for damage to the pin-type contacts, relay enclosure, and finishing material and corrective actions if necessary. This AD also requires doing a terminating modification, which ends the repetitive inspections. This AD results from a report of a burning drain hose and smoke caused by an overheated pitot static heating relay. We are issuing this AD to prevent over-heating of a certain pitot static heating relay, which could result in the burning of the windowsill drain hoses and consequent smoke or fire in the airplane cockpit.
