2009-08-11: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: This Airworthiness Directive (AD) is prompted by some occurrences where the Deice Pressure Regulator has vented too much hot air into the forward compartment damaging the oxygen cylinder ON/OFF cable, the Ram-Air Scoop cable and the Environmental Control System (ECS) firewall shut-off valve cable. If incorrectly adjusted, or defective, the Deice Pressure Regulator can vent hot air into the forward compartment. This situation can cause overheating and failures of components located inside the forward compartment, which could result in potential loss of several functions essential for safe flight. We are issuing this AD to require actions to correct theunsafe condition on these products.

2009-08-04: We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model BH.125 series 600A airplanes and Model HS.125 series 700A airplanes. This AD requires inspecting the wiring diagrams containing the cockpit blowers and comparing with the current airplane configuration, and reworking the wiring if necessary. This AD results from a report indicating that a blower motor of the cockpit ventilation and avionics cooling system 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.
80-08-14: 80-08-14 PURE-AIR, INC.: Amendment 39-3745. Applies to all aircraft using the Pure-Air, Inc. carburetor air inlet filter installed per STC SA69NW. Compliance is required as indicated. A. Within 60 days from the effective date of this AD, unless already accomplished. 1. Remove Pure-Air filter foam elements which have been installed for more than 100 hours time in service or one year, whichever occurs first, and install screen (PN M-117 Large or PN M-118 Small) on the downstream inside surface of the filter box (PN M-102 Large or PN M-101 Small) by means of the filter attach bolts. 2. Replace each Pure-Air filter element which has accumulated either 100 hours or one year in service with a new filter element. B. Replace the foam filter element: 1. Every 100 hours time in service or 12 calendar months, whichever comes first. 2. Any time the filter element becomes 50% covered with any foreign material. C. Install the new Pure-Air supplies decal, which reflects the above replacement times, in plain view on the upper right hand outside surface of the filter box.

2009-06-18: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Following in-flight test deployments on CL-600-2B19 aircraft, several Air-Driven generators (ADGs) failed to come on-line. Investigation revealed that, as a result of a wiring anomaly that had not been detected during ADG manufacture, a short circuit was possible between certain internal wires and their metallic over- braided shields, which could result in the ADG not providing power when deployed. The unsafe condition is that failure of the ADG could lead to loss of several functions essential for safe flight. We are issuing this AD to require actions to correct the unsafe condition on these products.
