This AD applies to Gulfstream Aerospace Corporation Model GVII-G500 airplanes having serial numbers (S/Ns) 72001 through 72111 inclusive; and GVII-G600 airplanes having S/Ns 73001 through 73106 inclusive; certificated in any category, with flight control computer (FCC) software revisions installed as specified in figure 1 to paragraph (c) of this AD.
| Model | Nomenclature | Gulfstream Aerospace Corporation part No. (P/N) | Thales P/N |
|---|---|---|---|
| GVII-G500 airplanes | FCC COM-MON Module A FCC COM-MON Module B | 72P2700001Z100-SW6.3 72P2700001Z200-SW6.3 | C13204JB01 C13212JB01 |
| GVII-G600 airplanes | FCC COM-MON Module A FCC COM-MON Module B | 72P2700001Z100-SW8.1 72P2700001Z200-SW8.1 | C13204KB01 C13212KB01 |
Note 1 to paragraph (c): The FCC software label, which identifies the software revision installed, can be found on the face of the FCC module. The FCC modules are installed within the left and right electronic equipment racks. The labels may be viewed by opening the rack doors and removing 4 screws per FCC (8 screws total per airplane) from the FCC cover.
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 reports of two landing incidents in which the alpha limiter engaged in the landing flare in unstable air, resulting in high rate of descent landings and damage to the airplanes. This AD requires updating the flight control computer (FCC) software. The FAA is issuing this AD to address the unsafe condition on these products.
Within 90 days after the effective date of this AD, update the FCC software in accordance with either:
(1) Gulfstream GVII-G500 Aircraft Service Change No. 039, Revision A, dated September 13, 2022, including Thales Service Bulletin C13204J-27-002, Revision 01, dated September 13, 2022, and Thales Service Bulletin C13212J-27-002, Revision 01, dated September 13, 2022; or Gulfstream GVII-G600 Aircraft Service Change No. 029, Revision A, dated September 13, 2022, including Thales Service Bulletin C13204K-27-002, Revision 01, dated September 13, 2022, and Thales Service Bulletin C13212K-27-002, Revision 01, dated September 13, 2022; as applicable; or
(2) A method approved by the Manager, East Certification Branch, FAA.
Accomplishing the software update required by paragraph (g) of this AD on an airplane terminates all requirements of AD 2020-02-18 and AD 2022-10-05, for that airplane only.
Although Gulfstream GVII-G500 Aircraft Service Change No. 039, Revision A, dated September 13, 2022, including Thales Service Bulletin C13204J-27-002, Revision 01, dated September 13, 2022, and Thales Service Bulletin C13212J-27-002, Revision 01, dated September 13, 2022; and Gulfstream GVII-G600 Aircraft Service Change No. 029, Revision A, dated September 13, 2022, including Thales Service Bulletin C13204K-27-002, Revision 01, dated September 13, 2022, and Thales Service Bulletin C13212K-27-002, Revision 01, dated September 13, 2022; specify to submit certain information to the manufacturer, this AD does not include that requirement.
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.
