To prevent structural damage to the vertical tail caused by a damaged vertical tail attachment bracket, which could result in loss of control of the airplane, accomplish the following:
(a) Within the next 50 hours time-in-service after the effective date of this AD, inspect the bracket that attaches the vertical tail front spar to the horizontal stabilizer for damage (cracks, broken lugs or bolts, or elongated holes) in accordance with the ACCOMPLISHMENT INSTRUCTIONS: I. Inspection, section of Ayres SB No. SB-AG-32, dated February 12, 1993.
(b) If any damage is found to the bracket during the inspection specified in paragraph (a) of this AD, prior to further flight, replace the bracket with an aluminum bracket, part number (P/N) 40301T007, and install a new close out plate, P/N 40309T003, in accordance with the ACCOMPLISHMENT INSTRUCTIONS: II. Repair, section of Ayres SB No. SB-AG-32, dated February 12, 1993.
(c) Within the next 100 hours TIS after the effective date of this AD, unless already accomplished in accordance with paragraph (b) of this AD, replace the bracket with an aluminum bracket, part number (P/N) 40301T007, and install a new close out plate, P/N 40309T003, in accordance with the ACCOMPLISHMENT INSTRUCTIONS: II. Repair, section of Ayres SB No. SB-AG-32, dated February 12, 1993.
(d) The replacement required by paragraph (c) of this AD may be accomplished instead of the inspection specified in paragraph (a) of this AD provided it is accomplished at or prior to the 50-hour TIS compliance time.
(e) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished.
(f) An alternative method of compliance or adjustment of the initial or repetitive compliance times that provides an equivalent level of safety may be approved by the Manager, Atlanta Aircraft Certification Office, 1669 Phoenix Parkway, Suite 210C, Atlanta, Georgia 30349. The request shall be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Atlanta Aircraft Certification Office.

(g) The inspection and replacement required by this AD shall be done in accordance with Ayres Service Bulletin No. SB-AG-32, dated February 12, 1993. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51. Copies may be obtained from the Ayres Corporation, P.O.
