Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 Airplanes; and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes

الملخص

The FAA proposes to adopt 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 proposed AD would require 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 proposed AD also would require doing a terminating modification, which ends the repetitive inspections. This proposed AD results from a report of a burning drain hose and smoke caused by an overheated pitot static heating relay. We are proposing this AD to prevent overheating 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.
