Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede Airworthiness Directive (AD) 2015-24- 06, which applies to certain Gulfstream Aerospace Corporation Model GVI airplanes. AD 2015-24-06 requires 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. Since we issued AD 2015-24-06, a modification of the MLG and brake assembly has been developed that when incorporated would terminate the need for the repetitive actions of AD 2015-24-06. This proposed AD would require modifying the MLG and brake assembly. We are proposing this AD to address the unsafe condition on these products.
