Federal Aviation Administration June 18, 2018 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes
Document Number: 2018-12892
Type: Rule
Date: 2018-06-18
Agency: Federal Aviation Administration, Department of Transportation
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.
Airworthiness Directives; Pacific Aerospace Limited Airplanes
Document Number: 2018-12886
Type: Proposed Rule
Date: 2018-06-18
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2015-23- 03 for Pacific Aerospace Limited Model 750XL airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as fatigue cracks on the fin forward pickup plates. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
