Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Corporation Ltd Model 750XL airplanes. This proposed AD would require 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 proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand. We are issuing this proposed AD to prevent structural failure of the outer panel and spar due to 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.
