What to do
Operators of Gulfstream Model GVI airplanes must revise their airplane flight manuals by adding the specified supplement no later than December 30, 2019. They should also monitor for future FAA communications regarding a terminating modification. Comments on the directive are accepted until January 27, 2020.
Summary
Federal Aviation Administration Airworthiness Directive 2019-23-11 is a final rule affecting all Gulfstream Aerospace Corporation Model GVI airplanes. It requires revising the airplane flight manual by adding a supplement with new operating limitations and abnormal procedures related to loss of rudder or yaw damper. This directive addresses a safety issue identified after an inflight rudder shutdown caused lateral-directional oscillations.
What changed
This new airworthiness directive mandates the incorporation of an airplane flight manual supplement that imposes altitude and airspeed limitations and revised abnormal procedures for rudder or yaw damper loss. It applies to all Model GVI airplanes regardless of prior modifications and serves as an interim safety measure until a terminating modification is developed.
Why it matters
This directive is critical for aviation professionals because it mitigates the risk of uncontrollable lateral-directional oscillations following a rudder shutdown, which could lead to catastrophic structural damage or loss of control. Operators and maintenance teams must ensure compliance to maintain safe flight operations and avoid potential accidents.
