2005-24-07: Left and right outer panel attachment lugs

2005-24-07 Pacific Aerospace Corporation Ltd.: Amendment 39-14387; Docket No. FAA-2005-21935; Directorate Identifier 2005-CE-37-AD. When Does This AD Become Effective? (a) This AD becomes effective on December 29, 2005. What Other ADs Are Affected by This Action? (b) None. What Airplanes Are Affected by This AD? (c) This AD affects Model 750XL, serial numbers 101 through 115, that are certificated in any category. What Is the Unsafe Condition Presented in This AD? (d) This AD is the result of incorrect sizing of the attachment lug spacers causing the lugs to distort when the attachment bolt is tightened. Also, outer wing attachment lugs were used to secure the spar in the wing build jig without spacers. This may have bent the clevis legs outward. These two problems may cause cracking and/or degradation of fatigue life. The actions specified in this AD are intended to prevent structural failure of the outer panel and spar due to a cracked, bent, or distorted condition of the left and right outer panel attachment lugs; and incorrect spacing of the left and right outer panel attachment lugs. This failure could lead to loss of control of the airplane. What Must I Do To Address This Problem? (e) To address this problem, you must do the following: Actions Compliance Procedures (1) Inspect the left and right outer panel, paired center wing lugs, and the outer panel single lugs for damage (scoring or gouging). Upon accumulating 300 hours time-in-service (TIS) or within 50 hours TIS after December 29, 2005 (the effective date of this AD), whichever occurs later. Follow Pacific Aerospace Corporation Ltd. Mandatory Service Bulletin PACSB/XL/015, Issue 3, amended April 8, 2005. (2) Inspect the left and right outer panel, paired center wing lugs, and the outer panel single lugs for cracks. You must use a fluorescent penetrant inspection procedure instead of the dyepenetrant inspection procedure stated in the service information. Upon accumulating 300 hours TIS or within 50 hours TIS after December 29, 2005 (the effective date of this AD), whichever occurs later. Follow Pacific Aerospace Corporation Ltd.

(3) If any damage and/or cracks are found during the inspections required in paragraph (e)(1) and (e)(2) of this AD, you must replace the lugs. Prior to further flight, after any inspection where damage and/or cracks are found. Follow Pacific Aerospace Corporation Ltd. Mandatory Service Bulletin PACSB/XL/015, Issue 3, amended April 8, 2005. (4) Inspect the left and right wing paired lugs for parallel spacing within 0.010 inches. If the paired lugs are not parallel within 0.010 inches, reshim outer wing attachment points and correct spacing. Inspect upon accumulating 300 hours TIS or within 50 hours TIS after December 29, 2005 (the effective date of this AD), whichever occurs later.
