AD 2008-07-10 73 FR 18706

The FAA is adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation (HBC) Models B200, B200GT, B300, and B300C airplanes. This AD requires you to fabricate and install a placard incorporating information that limits operation when there is known or forecast icing and requires you to replace a section of the pneumatic supply tube for the tail deice system with a new tube of a different material. This AD results from reports of collapsed tail deice boot pneumatic supply tubes. We are issuing this AD to prevent collapsed pneumatic supply tubes, which could result in failure of the tail deice boots to operate. This failure could lead to loss of control in icing conditions.
