Airworthiness Directive · Amendment 39-22905 · Fuel
Gulfstream Aerospace Corporation Airplanes
This AD applies to the Gulfstream Aerospace Corporation airplanes, certificated in any category, identified in paragraphs (c)(1) and (2) of this AD.
(1) Model GVII-G500 airplanes, having serial numbers (S/Ns) 72001 through 72139 inclusive.
(2) Model GVII-G600 airplanes, having S/Ns 73001 through 73144 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model GVII-G500 and GVII-G600 airplanes. This AD was prompted by a report of cracking in the electrical grounding receptacles located on the left and right wings. This AD requires inspecting the electrical grounding receptacles for cracks and corrosion, performing applicable on-condition actions, and sealing over the grounding receptacles on the top of the wings to permanently disable the receptacle. The FAA is issuing this AD to address the unsafe condition on these products.
Within 36 months after the effective date of this AD, do the actions specified in paragraphs (g)(1) and (2) of this AD, in accordance with Gulfstream GVII-G500 Customer Bulletin No. 089 or Gulfstream GVII-G600 Customer Bulletin No. 058, both dated November 28, 2023, as applicable.
(1) Do borescope inspections for cracking and corrosion of the interior walls of the grounding receptacle casing and do all applicable corrective actions before further flight.
(2) Remove the “GROUND HERE” decal/stencil from the grounding receptacles and apply epoxy over the ground receptacle area to permanently disable the grounding receptacles.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
