Airworthiness Directive · Amendment 39-16075 · Hawker Beechcraft Corporation (Type Certificate Previously Held by Raytheon Aircraft Company) Models 1900, 1900C, and 1900D Airplanes
Hawker Beechcraft Corporation (Type Certificate Previously Held by Raytheon Aircraft Company) Models 1900, 1900C, and 1900D Airplanes
This AD applies to the following airplane models and serial numbers that are certificated in any category:
| Serial numbers | |
|---|---|
| Group 1 Model Airplanes | |
| (1) 1900 | UA-3. |
| (2) 1900C | UB-1 through UB-74. |
| Group 2 Model Airplanes | |
| (1) 1900C (C-12J) | UC-1 through UC-174, and UD-1 through UD-6. |
| (2) 1900D | UE-1 through UE-439. |
We are adopting a new airworthiness directive (AD) to supersede AD 2006-24-11, which applies to certain Hawker Beechcraft Corporation (HBC) (Type Certificate previously held by Raytheon Aircraft Company) Models 1900, 1900C, and 1900D airplanes. AD 2006-24- 11 currently requires you to repetitively inspect the forward, vertical, and aft flanges of both the left and right wing rear spar lower caps for cracks, repair any cracks found, and report the inspection results to the manufacturer. Since we issued AD 2006-24-11, the manufacturer has developed a modification kit to install on the wing rear spar lower caps that will terminate the 200-hour repetitive inspection required in AD 2006-24-11. Consequently, this AD requires installing the new modification kits on the wing rear spar lower caps and terminates the repetitive inspections required in AD 2006-24-11 when the kits are installed. We are issuing this AD to prevent fatigue cracks in the wing rear spar lower caps, which could result in fatigue failure of the wing rear spar lower caps. A rear spar failure could result in complete wing failure and the wing separating from the airplane.
To address this problem, you must do the following, unless already done:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) For Group 1 and Group 2 airplanes: Repetitively inspect both the left and right wing rear spar lower caps for cracks and other damage, such as loose or missing fasteners. | Repetitively inspect at intervals not to exceed 200 hours time-in-service (TIS) after the last inspection required by AD 2006-24-11. | Follow the procedures in Raytheon Mandatory Service Bulletin 57-3815, Issued: October 2006. |
| (2) For Group 1 and Group 2 airplanes: If cracks are found, repair all cracks by obtaining and incorporating an FAA-approved repair scheme from the manufacturer. | Before further flight after any inspection required by paragraph (e)(1) of this AD where cracks are found. | For the repair scheme, contact Hawker Beechcraft Corporation at P.O. Box 85, Wichita, Kansas 67201-0085; phone: (800) 429-5372; fax: (316) 676-8745; e-mail: tom_peay@rac.ray.com. |
| (3) For Group 1 and Group 2 airplanes: Report the inspection results to Hawker Beechcraft Company (formerly Raytheon Aircraft Company) using the instructions and forms in the service bulletin. Complete all sections of the required forms. Reporting requirements have been approved by the Office of Management and Budget (OMB) and assigned OMB control number 2120-0056. | Report the repetitive inspection results within 30 days after the inspection. | Follow the procedures in Raytheon Mandatory Service Bulletin 57-3815, Issued: October 2006. |
| (4) For Group 1 airplanes: Install Modification Kit 114-4052-1 and Modification Kit 114-4067-0001. | Upon reaching 22,000 total hours TIS or within the next 3 years after December 14, 2009 (the effective date of this AD), whichever occurs later. Installing the modification kits terminates the repetitive inspections required by paragraph (e)(1) of this AD. | Follow the procedures in Hawker Beechcraft Mandatory Service Bulletin SB 57-3816, Issued: January 2008. For further assistance with procedures for shoring an airplane, you may contact the manufacturer at the address specified in paragraph (h)(3) of this AD. |
| (5) For Group 2 airplanes: Install Modification Kit 118-4012-1 or 118-4012-3 and Modification Kit 118-4014-0003. | Upon reaching 22,000 total hours TIS or within the next 3 years after December 14, 2009 (the effective date of this AD), whichever occurs later. Installing the modification kits terminates the repetitive inspections required by paragraph (e)(1) of this AD. | Follow the procedures in Hawker Beechcraft Mandatory Service Bulletin SB 57-3816, Issued: January 2008. For further assistance with procedures for shoring an airplane, you may contact the manufacturer at the address specified in paragraph (h)(3) of this AD. |
| (6) For all affected Group 1 and Group 2 airplanes: You may install the modification kits specified in paragraphs (e)(4) and (e)(5) of this AD at any time before the required compliance times specified in paragraphs (e)(4) and (e)(5) of this AD. Installing the modification kits terminates the repetitive inspections required by paragraph (e)(1) of this AD. | As of December 14, 2009 (the effective date of this AD). | Not applicable. |
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.
