Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
This AD applies to Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Astra SPX, 1125 Westwind Astra, and Gulfstream 100 airplanes, serial numbers 002 through 158 inclusive, certificated in any category.
We are adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Astra SPX, 1125 Westwind Astra, and Gulfstream 100 airplanes. This AD was prompted by a report indicating that sponge rubber padding was found between wheel well fuel lines and electrical harnesses. This AD requires inspecting for the presence of sponge rubber padding and for proper separation of the fuel lines and electrical harnesses in the wheel well area, and corrective actions if necessary. We are issuing this AD to detect and correct corrosion or chafing of the fuel lines, which could result in fuel leakage and possible fire in the wheel well area.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 24 months after the effective date of this AD, inspect for the presence of sponge rubber padding on the fuel lines in the wheel well area and inspect the fuel lines and electrical harnesses in the wheel well area for proper separation, in accordance with the Accomplishment Instructions of Gulfstream Service Bulletin 100-28-297, dated January 21, 2010.
(1) If any sponge rubber padding is found, before further flight, remove all sponge rubber padding from the fuel lines, inspect the fuel lines that were covered with the rubber padding for any corrosion and repair or replace as applicable any corroded or chafed fuel lines, in accordance with the Accomplishment Instructions of Gulfstream Service Bulletin 100-28-297, dated January 21, 2010.
(2) If any fuel lines and electrical harnesses are found to not have proper separation, before further flight, install loop clamps in accordance with the Accomplishment Instructions of Gulfstream Service Bulletin 100-28-297, dated January 21, 2010.
(3) If proper separation is found, and no sponge rubber padding is found, no further action is required by this paragraph.
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.
