Federal Aviation Administration December 5, 2017 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2017-26040
Type: Rule
Date: 2017-12-05
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757-200, -200PF, and -300 series airplanes. This AD was prompted by reports of cracking found at a certain fuselage frame inner chord. This AD requires repetitive inspections for any cracking of a certain fuselage frame inner chord; identification of the material of a certain fuselage frame inner chord for certain airplanes; and applicable corrective actions. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters
Document Number: 2017-26039
Type: Proposed Rule
Date: 2017-12-05
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2017-02- 07 for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 and Model MBB-BK 117 D-2 helicopters. AD 2017-02-07 currently requires a repetitive inspection and a one-time torque of each hydraulic module plate assembly attachment point (attachment point). Since we issued AD 2017-02-07, a terminating action has been developed to address the unsafe condition. This proposed AD would retain the initial inspection and torque requirements of AD 2017-02-07 and require replacing the attachment point hardware. The actions of this proposed AD are intended to prevent an unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
Document Number: 2017-26037
Type: Rule
Date: 2017-12-05
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Airbus Model A318 series airplanes; Model A319 series airplanes; and Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes. This AD was prompted by a report indicating that the lower rib foot angle of the center wing box did not match with the bottom skin panel inner surface. This AD requires repetitive inspections for cracking of the external bottom skin in certain areas on the left and right wings, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2017-24811
Type: Proposed Rule
Date: 2017-12-05
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-300, -400, -500, -600, -700, -700C, -800, -900, and -900ER series airplanes; Model 757 airplanes; Model 767 airplanes; Model 777 airplanes; and Model 787-8 and 787-9 airplanes. This proposed AD was prompted by reports of fuel crossfeed valves failing to open when activated during flight. This proposed AD would require, for certain airplanes, revising the airplane flight manual (AFM); and for certain other airplanes, revising the minimum equipment list (MEL) to do an operational check of the fuel crossfeed valve prior to each extended range operations (ETOPS) flight if one fuel crossfeed valve (or the fuel balancing system on Model 787 airplanes) is inoperative. We are proposing this AD to address the unsafe condition on these products.
