AD NUMBER: 2006-04-02
SUBJECT: Airworthiness Directive 2006-04-02
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.
