Federal Aviation Administration December 5, 2016 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2016-28668
Type: Proposed Rule
Date: 2016-12-05
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model MD-90-30 airplanes. This proposed AD was prompted by a report of cracking in a horizontal stabilizer rear spar cap. This proposed AD would require repetitive open hole eddy current high frequency (ETHF) or surface eddy current low frequency (ETLF) inspections for any crack in the left and right side horizontal stabilizer rear spar upper caps, and repair or replacement if necessary. We are proposing this AD to prevent the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2016-28664
Type: Proposed Rule
Date: 2016-12-05
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the web lap splices in the aft pressure bulkhead are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections of the web lap splices in the aft pressure bulkhead for cracking of the fastener holes, and repair if necessary. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2016-28631
Type: Proposed Rule
Date: 2016-12-05
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-800, -900, and -900ER series airplanes. This proposed AD was prompted by reports indicating in- flight valve failure of the left temperature control valve and control cabin trim air modulating valve. This proposed AD would require replacing the left temperature control valve and control cabin trim air modulating valve. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Fokker Services B.V. Airplanes
Document Number: 2016-28601
Type: Rule
Date: 2016-12-05
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This AD was prompted by heavy corrosion found on the wing rear spar lower girder. This AD requires inspections of the affected areas, modification of the wing trailing edge lower skin panels, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Dassault Aviation Airplanes
Document Number: 2016-28600
Type: Rule
Date: 2016-12-05
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by investigation results that determined that a certain thickness of the fuel tank panels is insufficient to meet the certification requirements. This AD requires inspecting the thickness of the fuel tank panels, and repair if necessary. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2016-28340
Type: Rule
Date: 2016-12-05
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2A12 (CL-601 Variant), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This AD was prompted by a report that a potential chafing condition exists between the negative-G fuel feed drain line of the auxiliary power unit (APU) and its surrounding structure and components. This AD requires, for certain airplanes, a detailed inspection for chafing conditions of the negative-G fuel feed drain line of the APU, and corrective actions if necessary. For certain other airplanes, this AD requires replacement of the APU negative-G fuel feed tube assembly and the drain line. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2016-28337
Type: Rule
Date: 2016-12-05
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 707-300, 707-300B, and 707-300C series airplanes; and certain Model 727C, 727-100C, and 727-200F series airplanes. This AD was prompted by a report indicating that a cam latch on the main cargo door (MCD) broke during flight. This AD requires various inspections and related investigative and corrective actions, if necessary. We are issuing this AD to address the unsafe condition on these products.
