Unsafe condition

This AD was prompted by reports of unreliable airspeed indications that were caused by pitot heater resistance shorted to ground. We are issuing this AD to ensure proper flight crew awareness of unreliable airspeed indications. This condition, if not recognized by the flight crew, could possibly result in reduced control of the airplane.

Affected ADs

None.
