## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Raytheon Model HS.125 series 700A airplanes, Model BAe.125 series 800A airplanes, and Model Hawker 800 and Hawker 800XP airplanes. This AD requires inspecting to determine the current rating of the circuit breakers of certain cockpit ventilation and avionics cooling system blowers; and replacing the circuit breakers and modifying the blower wiring, as applicable. This AD results from a report indicating that a blower motor seized up and gave off smoke. We are issuing this AD to prevent smoke and fumes in the cockpit in the event that a blower motor seizes and overheats due to excessive current draw.
