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:
| Models | Serial Nos. |
|---|---|
| (1) 1900 | UA-3. |
| (2) 1900C (C-12J) | UB-1 through UB-74, UC-1 through UC-174, and UD-1 through UD-6. |
| (3) 1900D | UE-1 through UE-439. |
The FAA is adopting a new airworthiness directive (AD) for certain Raytheon Aircraft Company (RAC) Models 1900, 1900C, and 1900D airplanes. This AD contains the same information as emergency AD 2006- 18-51 and publishes the action in the Federal Register. This AD requires you to do a one-time visual inspection of both the left and right wing rear spar lower caps for cracking and other damage such as loose or missing fasteners; repair any cracks or damage found; and report any cracks or damage found to the FAA and RAC. This AD results from extensive cracks found in the wing rear spar lower caps and rear spar web of two of the affected airplanes. One of the airplanes also had missing fasteners. We are issuing this AD to detect and correct cracking and other damage in the wing rear spar lower caps of the affected airplanes before the cracks or damage lead to failure. Such a wing failure could result in the wing separating from the airplane with consequent loss of control.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) A one-time visual inspection of both the left and right wing rear spar lower caps for cracks and other damage such as loose or missing fasteners. | At whichever occurs later after September 8, 2006 (the effective date of this AD), except to those who received emergency AD 2006-18-51, which contained the requirements of this amendment and became effective immediately upon receipt: (i) Within 24 hours; or (ii) Prior to further flight. | Follow the procedures in the Appendix to this AD. |
| (2) For the inspection in paragraph (e)(1) of this AD, you may return/position the airplane to a home base, hangar, maintenance facility, etc. | For this repositioning, you may operate the airplane up to 3 hours time-in-service provided the flight(s) occur(s) no later than 30 days after September 8, 2006 (the effective date of this AD), except to those who received emergency AD 2006-18-51, which contained the requirements of this amendment and became effective immediately upon receipt. | The following limitations are imposed for such a repositioning flight: (i) ONLY THE PILOT AND ANY ADDITIONAL FLIGHT CREW MEMBER REQUIRED FOR SAFE OPERATION IS ALLOWED FOR THIS FLIGHT; (ii) FLIGHT INTO KNOWN OR FORECAST MODERATE OR SEVERE TURBULENCE IS PROHIBITED; and (iii) INDICATED AIRSPEED IS LIMITED TO 175 KNOTS MAXIMUM. |
| (3) Repair any cracks or other damage such as loose or missing fasteners found during the inspection required in paragraph (e)(1) of this AD. Do this by obtaining and incorporating an FAA-approved repair scheme from RAC. | Before further flight after the inspection required by paragraph (e)(1) of this AD. | Contact RAC at Post Office Box 85, Wichita, Kansas 67201-0085; phone: 316-676-8366; fax: (316) 676-8745; e-mail: tom_peay@rac.ray.com. |
| (4) Report the inspection results to the FAA and RAC. For the reporting requirement in this AD, under the provisions of the Paperwork Reduction Act, the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056. | Within 72 hours after completing the inspection required in paragraph (e)(1) of this AD. | Send your report to Steven E. Potter, FAA, 1801 Airport Road, Wichita, Kansas 67209; fax: (316) 946-4107; e-mail: steven.potter@faa.gov; and Tom Peay, Raytheon Aircraft Company, Post Office Box 85, Wichita, Kansas 67201-0085; fax: (316) 676-8745; e-mail: tom_peay@rac.ray.com. Include in your report the following information: (i) Aircraft model and serial number; (ii) Number of cycles; (iii) Aircraft hours TIS; (iv) Left and right wing lower spar cap hours TIS; (v) Hours TIS on the spar cap since last inspection; (vi) Answer yes or no whether cracking, missing fasteners, or other damage was found; and (vii) If cracking was found, identify size and location of cracks. |
