ACTION: Final rule; request for comments. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation (Gulfstream) Models GVI, GVII-G500, and GVII-G600 airplanes. This AD requires revising the airplane flight manual (AFM) by attaching an airplane flight manual supplement (AFMS), which contains new or revised operating limitations, abnormal procedures, and emergency procedures. This AD was prompted by reports of continued flight after a flight control 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 on the remaining, operable flight control surfaces. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective February 13, 2020. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of February 13, 2020. The FAA must receive comments on this AD by March 30, 2020.

SUPPLEMENTARY INFORMATION: Discussion The FAA has received at least 30 reports of the flight control computer (FCC) commanding flight control surfaces into damped by-pass mode (surface shutdown). During the investigation of these events, it was discovered that the existing GVI and GVII airplane flight manuals, in most cases, allow continued flight after a surface shutdown, and the GVI airplane flight manual allows takeoff with an inboard spoiler shutdown.
