Airworthiness Directive · Amendment 39-17069 · Wings
Gulfstream Aerospace Corporation Airplanes
This AD applies to all Gulfstream Aerospace Corporation Model G-1159, G-1159A, and G-1159B airplanes; certificated in any category.
We are adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model G-1159, G-1159A, and G-1159B airplanes. This AD requires, for certain airplanes, a measurement to determine the clearance (gap) of the exposed rounded portion of the doubler and clothespin fitting at the wing-to-fuselage attachment, and repair if necessary. This AD also requires, for certain other airplanes, determining if a certain aircraft service change has been incorporated, and for affected airplanes, a measurement to determine the clearance (gap) of the exposed rounded portion of the doubler and clothespin fitting at the wing-to-fuselage attachment, and repair if necessary. This AD was prompted by a report of an improper structural modification that had excessive gaps in the wing-to-fuselage attachment fittings. We are issuing this AD to detect and correct excessive gaps in the wing-to-fuselage attachment fittings, which could result in reduced structural integrity at the wing-to-fuselage attachment and consequent separation of the wing from the airplane.
For airplanes identified in paragraphs (g)(1) and (g)(2) of this AD: Before further flight, measure to determine the clearance (gap) of the exposed rounded portion of the doubler and clothespin fitting at the wing-to-fuselage attachment, in accordance with Gulfstream III Alert Customer Bulletin 21, including Service Reply Card, dated May 18, 2012 (for Model G-1159A airplanes); or Gulfstream II/IIB Alert Customer Bulletin 36, including Service Reply Card, dated May 18, 2012 (for Model G-1159 and G-1159B airplanes). If the clearance exceeds the limit specified in Gulfstream III Alert Customer Bulletin 21, including Service Reply Card, dated May 18, 2012 (for Model G-1159A airplanes); or Gulfstream II/IIB Alert Customer Bulletin 36, including Service Reply Card, dated May 18, 2012 (for Model G-1159 and G-1159B airplanes); before further flight, repair in accordance with a method approved by the Manager, Atlanta Aircraft Certification Office (ACO), FAA. For a repair method to be approved by the Manager, Atlanta ACO, as required by this paragraph, the Manager's approval letter must specifically refer to this AD.
