Airworthiness Directive · Amendment 39-14387 · Pacific Aerospace Corporation Ltd. Model 750XL Airplanes
Pacific Aerospace Corporation Ltd. Model 750XL Airplanes
This AD affects Model 750XL, serial numbers 101 through 115, that are certificated in any category.
The FAA adopts a new airworthiness directive (AD) for certain Pacific Aerospace Corporation Ltd Model 750XL airplanes. This AD requires you to inspect the condition of the left and right outer panel attachment lugs for damage (scoring and gouging) and/or cracks (using a fluorescent penetrant inspection procedure for the crack inspection); to inspect the spacing of left and right outer panel attachment lugs; to replace the lugs if damage is found; and to make necessary corrections to the spacing. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand. We are issuing this AD 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.
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 dye penetrant 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. Mandatory Service Bulletin PACSB/XL/015, Issue 3, amended April 8, 2005. |
| (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. Correct spacing and reshim prior to further flight after the inspection | Follow Pacific Aerospace Corporation Ltd. Mandatory Service Bulletin PACSB/XL/015, Issue 3, amended April 8, 2005. |
