Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes
Document Number: 2015-30629
Type: Rule
Date: 2015-12-04
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model GVI airplanes. This AD requires repetitive breakaway torque checks and torqueing of the brake inlet self-sealing couplings. This AD also requires revising the airplane flight manual to include procedures to follow in the event of certain display indications. This AD was prompted by reports of the self- sealing couplings on the brake inlet fitting that have been found backed out of the fully seated position. We are issuing this AD to detect and correct inadequate torque on the self-sealing coupling. This condition could result in an unannounced total loss of braking capability on one or multiple brakes, which could result in a runway overrun or asymmetrical braking that can lead to a lateral runway excursion.
