AD NUMBER: 2012-11-06

PRODUCT: All Gulfstream Aerospace Corporation Model G-1159, G-1159A, and G-1159B airplanes.
SUBJECT: Airworthiness Directive 2012-11-06
ACTION: Final Rule

SUMMARY: 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. The FAA is 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.

DATES: This AD is effective May 29, 2012.
