Beechcraft Corporation Airplanes
This AD applies to the following Beechcraft Corporation airplanes in table 1 of this AD, certificated in any category:
| Model | Serial Numbers |
|---|---|
| 1900 | UA-3. |
| 1900C | UB-1 through UB-74, UC-1 through UC-174. |
| 1900C (C-12J) | UD-1 through UD-6. |

We are adopting a new airworthiness directive (AD) for certain Beechcraft Corporation (type certificate previously held by Hawker Beechcraft Corporation) Models 1900, 1900C, and 1900D airplanes. This AD was prompted by reports of cracking in the front spar cap angles and hat section structure of the vertical stabilizer. This AD requires inspections of the vertical stabilizer spar angles and hat section for cracks with corrective actions as necessary. We are issuing this AD to correct the unsafe condition on these products.
(1) For all airplanes: Within the next 600 hours time-in-service (TIS) after January 13, 2014 (the effective date of this AD), inspect part number (P/N) 101-640011-3/-4 spar angles and P/N 114-640000-25/-26 hat section for cracks following the Accomplishment Instructions in paragraph 3.A. of Hawker Beechcraft Mandatory Service Bulletin SB 55-4114, dated August 2012.

Follow Procedure 6.c. under Vertical Stabilizer Canted Stabilizer Station (CSS 69.184 through VSS 91.10) in the “I” Check Procedures of Beechcraft Corporation Model 1900D Airliner Structural Inspection Manual, Part Number 129-590000-65E5, dated May 1, 2013.
If any cracks are found during any of the inspections required in paragraph (g) of this AD, to include all subparagraphs, before further flight, you must contact Beechcraft Corporation to obtain repair instructions approved by the Wichita Aircraft Certification Office (ACO) specifically for compliance with this AD and incorporate those instructions. You can find contact information for Beechcraft Corporation in paragraph (l)(3) of this AD.
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.
