We are adopting a new airworthiness directive (AD) for all Augustair, Inc. Models 2150, 2150A, and 2180 airplanes. This AD requires you to inspect the vertical stabilizer front spar for cracks and loose fasteners, repair any cracks and loose fasteners found, and reinforce the vertical stabilizer spar regardless if cracks are found. This AD results from six reports of airplanes with a cracked vertical stabilizer front spar. We are issuing this AD to detect and correct cracks in the vertical stabilizer front spar, which could result in separation of the vertical stabilizer from the airplane. This failure could lead to loss of control.
To address this problem, you must do the following, unless already done:
(1) Before further flight after March 24, 2010 (the effective date of this AD), visually inspect the vertical stabilizer front spar for cracks and other damage (loose fasteners, corrosion, scratches) following section 2, paragraph A, of Augustair Service Bulletin SB2009-1, Revision B, dated February 2, 2010.
(2) At the applicable compliance time specified in paragraph (f)(2)(i) and (f)(2)(ii) of this AD, do a detailed inspection of the vertical stabilizer front spar for cracks and other damage, repair any damage found, and install a doubler to the vertical stabilizer front spar following section 2, paragraph B, of Augustair Service Bulletin SB2009-1, Revision B, dated February 2, 2010.
(i) Before further flight after the inspection required in paragraph (f)(1) of this AD where cracks or other damage is found; or
(ii) Within 10 hours time-in-service (TIS) after the inspection required in paragraph (f)(1) of this AD where no cracks or other damage was found.
(3) Report the inspection results from paragraph (f)(2) of this AD within 30 days after the inspection or within 30 days after March 24, 2010 (the effective date of this AD), whichever occurs later. Send your report to ATTN: Hal Horsburgh, Aerospace Engineer, FAA, Atlanta Aircraft Certification Office (ACO), 1701 Columbia Avenue, College Park, Georgia 30337; fax: (404) 474-5606; e-mail: hal.horsburgh@faa.gov. The Office of Management and Budget (OMB) approved the information collection requirements contained in this regulation under the provisions of the Paperwork Reduction Act and assigned OMB Control Number 2120-0056. Include in your report the following information:
(1) Aircraft model and serial number;
(2) Aircraft hours TIS;
(3) Answer whether any crack was found and, if so, the crack location and size;
(4) Description of any previous modifications or repairs in the vertical stabilizer spar attachment area or if the airplane was modified with a different engine model or propeller model than originally installed on the airplane and hours TIS when the modification was done;
(5) Corrective action taken;
(6) Answer yes or no whether other damage was found; and if so, describe it;
(7) Point of contact name and phone number; and
(8) Clearly identify the AD No., Docket No., and Directorate Identifier of the AD action requiring the report.
