Models named: GVI, GVII-G500, GVII-G600. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to Gulfstream Aerospace Corporation Models GVI, GVII-G500, and GVII-G600 airplanes, all serial numbers, certificated in any category.

Compliance

Comply with this AD within 15 days after February 13, 2020 (the effective date of this AD), unless already done. (1) Revise the airplane flight manual (AFM) for your airplane by attaching the applicable airplane flight manual supplement (AFMS) specified in paragraphs (f)(1)(i) through (iv) of this AD. When these flight manual changes have been included in a future revision of the AFM, you may insert the revisions in the limitations, abnormal procedures, and emergency procedures sections of the AFM, provided the information is identical to that in the AFMS, and then you may remove the AFMS. (i) Gulfstream Aerospace G650 Airplane Flight Manual Supplement No. G650-2019-04, dated December 16, 2019. (ii) Gulfstream Aerospace G650ER Airplane Flight Manual Supplement No. G650ER-2019-04, dated December 16, 2019. (iii) Gulfstream Aerospace GVII-G500 Airplane Flight Manual Supplement No. GVII-G500-2019-08, dated December 16, 2019. (iv) Gulfstream Aerospace G600 Airplane Flight Manual Supplement No. GVII-G600-2019-02, dated December 16, 2019. (2) The action required by paragraph (f)(1) of this AD may be performed by the owner/operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with 14 CFR 43.9(a)(1) through (4), and 14 CFR 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 121.380, or 135.439.

Required actions

Special flight permits are prohibited for this AD in accordance with 14 CFR 39.23.

Unsafe condition

This AD was prompted by reports of continued flight after the flight control computer (FCC) has commanded flight control surfaces into a damped by-pass mode (surface shutdown). If flight is continued after a flight control surface shutdown, the airplane is left without protection against flight control surface hard-over and force fight events. The FAA is issuing this AD to provide operating limitations and flight crew procedures in the event of loss of protection against flight control surface hard-over and force fight events. The unsafe condition, if not addressed, could result in loss of structural integrity and loss of control of the airplane.

Affected ADs

None.
