Airworthiness Directive · Amendment 39-19311 · Landing gear
Gulfstream Aerospace Corporation Airplanes
This AD applies to Gulfstream Aerospace Corporation Model GVI airplanes, serial numbers 6001 and 6003 through 6163, certificated in any category.
Note 1 to paragraph (c) of this AD: Model GVI airplanes are also referred to by the marketing designations G650 and G650ER.
We are superseding Airworthiness Directive (AD) 2015-24-06 for certain Gulfstream Aerospace Corporation Model GVI airplanes. AD 2015- 24-06 required repetitive breakaway torque checks and torqueing of the main landing gear (MLG) brake inlet self-sealing couplings and inserting a dispatch and takeoff limitation to the limitations section of the airplane flight manual. This AD requires modifying the MLG and brake assembly. This AD was prompted by reports of the self-sealing couplings on the MLG brake inlet fitting backing out of the fully seated position. We are issuing this AD to address the unsafe condition on these products.
(1) Within 6 months after July 23, 2018 (the effective date of this AD), modify the MLG and brake assemblies following the Accomplishment Instructions in Gulfstream G650 Customer Bulletin Number 155B, dated July 26, 2017; and Gulfstream G650ER Customer Bulletin Number 155B, dated July 26, 2017.
(2) Although Gulfstream G650 Customer Bulletin Number 155B, dated July 26, 2017; and Gulfstream G650ER Customer Bulletin Number 155B, dated July 26, 2017, both contain reporting requirements and return of certain parts to the manufacturer, this AD does not include those requirements.
(3) AD 2015-24-06 required a dispatch and takeoff limitation in the airplane flight manual. Although we did not retain that requirement in this AD, if not already removed, this limitation should be removed after the modification in paragraph (g)(1) of this AD is done.
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.
