Required actions
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).

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. (1) Model G-1159, and G-1159B airplanes, having serial numbers (S/N) 083, 084, 096, 130, 176, 202, 238, 239, and 240. (2) Model G-1159A airplanes, having S/N 346, 355, 385, and 486.
Unsafe condition
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.
Affected ADs
None.
