Federal Aviation Administration June 1, 2018 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2018-11693
Type: Proposed Rule
Date: 2018-06-01
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777-200 and -300 series airplanes. This proposed AD was prompted by reports of unreliable performance of the water and fuel scavenge system; failure of the fuel scavenge function can cause trapped fuel, resulting in unavailable fuel reserves. This proposed AD would require incorporating operating limitations, or modifying the water and fuel scavenge systems in the fuel tanks and certain electrical panels. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
Document Number: 2018-11692
Type: Proposed Rule
Date: 2018-06-01
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2006-07- 26, which applies to all ATR-GIE Avions de Transport R[eacute]gional Model ATR42 airplanes. AD 2006-07-26 requires a one-time inspection to detect discrepancies (e.g., cracking, loose/sheared fasteners, distortion) of the upper skin and rib feet of the outer wing boxes, and repair if necessary. Since we issued AD 2006-07-26, we have received reports of cracking in these same areas on other Model ATR42 airplanes. This proposed AD would require repetitive inspections to detect discrepancies of the upper skin and rib feet of the outer wing boxes, and repair if necessary. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
Document Number: 2018-11680
Type: Proposed Rule
Date: 2018-06-01
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A310 series airplanes. This proposed AD was prompted by a determination that new or more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Dassault Aviation Airplanes
Document Number: 2018-11679
Type: Proposed Rule
Date: 2018-06-01
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 2000 and FALCON 2000EX airplanes. This proposed AD was prompted by reports of metallic debris found in the wing slat piccolo tubes; investigation revealed that the debris originated from the flow guide of the ball joint of the wing anti-ice valve. This proposed AD would require repetitive inspections for metallic debris and damage of the flow guide of the ball joint of the wing anti-ice valve, and related investigative and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
Special Conditions: Textron Aviation Inc. Model 700 Series Airplanes; Installed Rechargeable Lithium Batteries
Document Number: 2018-11455
Type: Rule
Date: 2018-06-01
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Textron Aviation Inc. (Textron) Model 700 series airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is the installation of rechargeable lithium batteries. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters (Previously Eurocopter Deutschland GmbH)
Document Number: 2018-11447
Type: Proposed Rule
Date: 2018-06-01
Agency: Federal Aviation Administration, Department of Transportation
We propose to revise Airworthiness Directive (AD) 2014-05-06 for Eurocopter Deutschland GmbH Model EC135 and MBB-BK 117C-2 helicopters. AD 2014-05-06 requires repetitive inspections of the flight-control bearings, replacing any loose bearings with airworthy flight-control bearings, and installing bushings and washers. This proposed AD would retain the requirements of AD 2014-05-06 but would remove the repetitive inspections. The actions of this proposed AD are intended to correct an unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
Document Number: 2018-11446
Type: Rule
Date: 2018-06-01
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) Airbus Helicopters Model SA-365C, SA-365C1, and SA-365C2 helicopters. This AD requires establishing a life limit of 2,000 hours time-in-service (TIS) for the Starflex star/mast connecting bolt (bolt) and removing from service each bolt that exceeds its life limit. This AD is prompted by the discovery that the bolt's life limit was not included in helicopter maintenance records. The actions of this AD are intended to prevent an unsafe condition on these products.
Airworthiness Directives; Bell Helicopter Textron Canada Helicopters
Document Number: 2018-11445
Type: Proposed Rule
Date: 2018-06-01
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 427 helicopters. This proposed AD would require inspecting the inboard skin of the vertical fin around the four tailboom attachment points. This proposed AD is prompted by reports of cracked vertical fin skins that resulted from metal fatigue. The actions of this proposed AD are intended to prevent an unsafe condition on these products.
Airworthiness Directives; Austro Engine GmbH Engines
Document Number: 2018-11378
Type: Proposed Rule
Date: 2018-06-01
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Austro Engine GmbH model E4 engines and for all model E4P engines. This proposed AD was prompted by reports of considerable wear on the timing chain on these engines. This proposed AD would require replacement of the timing chain and amending certain airplane flight manuals to limit use of windmill restarts. We are proposing this AD to address the unsafe condition on these products.
