Hawker Beechcraft Corporation Models B200, B200GT, B300, and B300C Airplanes
This AD applies to the following Hawker Beechcraft Corporation airplanes that are certificated in any category:
| Model | Serial numbers |
|---|---|
| B200 | BB-1926, BB-1978, and BB-1988 through BB-2000. |
| B200GT | BY-1 through BY-26. |
| B300 | FL-427, FL-493, and FL-500 through FL-573. |
| B300C (C-12W) | FM-14 through FM-18. |
We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires fabricating and installing a placard incorporating information that limits operation when there is known or forecast icing and requires replacing a section of the pneumatic supply tube for the tail deice system with a new tube of a different material. This AD requires fabricating and installing a placard incorporating information that limits operation when there is known or forecast icing and requires replacing the entire length of the pneumatic supply tube for the tail deice system with a new tube of a different material. This AD was prompted by reports of two failures of the pneumatic supply tube for the tail deice system outside the area covered by AD 2008-07-10. 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.
Comply with this AD within the compliance times specified, unless already done.
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Fabricate a placard (using at least 1/8-inch letters) with the following words and install the placard on the instrument panel within the pilot's clear view: “THIS AIRPLANE IS PROHIBITED FROM FLIGHT IN KNOWN OR FORECAST ICING.” | Before further flight in known or forecast icing conditions or within the next 3 days after December 20, 2010 (the effective of this AD), whichever occurs first | Not applicable. |
| (2) For Model B200 and Model B200GT airplanes: Replace the pneumatic supply tubing from the rear spar at Fuselage Station (FS) 227.00 to the aft pressure bulkhead at FS 347.750 with Hytrel tubing part number (P/N) 131823VH10D-1210; and for Model B300 and Model B300C airplanes: Replace pneumatic supply tubing from the rear spar at FS 241.40 to the aft pressure bulkhead at FS 381.750 with Hytrel tubing P/N 131823VH10D-1406. The replacement of tail deice boot pneumatic supply tubes required by paragraph (f)(2) of this AD is terminating action for the placard required by paragraph (f)(1) of this AD | Before further flight in known or forecast icing conditions, within 25 hours time-in-service (TIS) after December 20, 2010 (the effective date of this AD), or within 3 months after December 20, 2010 (the effective date of this AD), whichever occurs first | Follow the Accomplishment Instructions in Hawker Beechcraft Mandatory Service Bulletin SB 30-3889, Rev 1, dated October 2010. |
| (3) Remove the placard required by paragraph (f)(1) of this AD | Before further flight after the replacement of tail deice boot pneumatic supply tubes required by paragraph (f)(2) of this AD | Not applicable. |
If Hawker Beechcraft Mandatory Service Bulletin SB 30-3889, Issued: March 2008, has already been complied with, you may splice new Hytrel tubing on the existing Hytrel tubing in the aft evaporator bay area before further flight in known or forecast icing conditions, within 25 hours TIS after December 20, 2010 (the effective date of this AD), or within 3 months after December 20, 2010 (the effective date of this AD), whichever occurs first.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
