Federal Aviation Administration January 17, 2018 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Bombardier, Inc., Airplanes
Document Number: 2018-00664
Type: Proposed Rule
Date: 2018-01-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This proposed AD was prompted by a report indicating that certain lanyards for the passenger oxygen masks located in the airplane's entry area are too long. This proposed AD would require replacement of certain oxygen mask lanyards with shorter lanyards. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2018-00662
Type: Proposed Rule
Date: 2018-01-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of cracks found in the main landing gear (MLG) beam forward support fitting. This proposed AD would require repetitive inspections for cracking of the MLG beam forward support fitting, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bell Helicopter Textron Helicopters
Document Number: 2018-00660
Type: Rule
Date: 2018-01-17
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Bell Helicopter Textron (Bell) Model 204B, 205A, and 205A-1 helicopters with a Helicopter Technology Company (HTC) main rotor (M/R) blade installed. This AD requires cleaning and visually inspecting the M/R blades, and depending on the outcome of the inspection, repairing or replacing the M/R blades. This AD is prompted by a report of an M/R blade with a fatigue crack in the grip plate and doublers at the blade retention bolt hole. The actions of this AD are intended to correct an unsafe condition on these products.
Airworthiness Directives; The Enstrom Helicopter Corporation Helicopters
Document Number: 2018-00659
Type: Rule
Date: 2018-01-17
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 2015-08-51 for the Enstrom Helicopter Corporation (Enstrom) Model F-28A, 280, F-28C, F-28C-2, F-28C-2R, 280C, F-28F, F-28F-R, 280F, 280FX, and 480 helicopters. AD 2015-08-51 required an inspection of the main rotor spindle (spindle) and reporting the inspection results to the FAA. This new AD was prompted by additional reports of cracked spindles and requires establishing a life limit and a recurring inspection. The actions of this AD are intended to prevent the unsafe condition on these products.
Airworthiness Directives; Various Restricted Category Helicopters
Document Number: 2018-00658
Type: Rule
Date: 2018-01-17
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Model TH-1F, UH-1B, UH-1F, UH-1H, and UH-1P helicopters with a Helicopter Technology Company (HTC) main rotor (M/R) blade installed. This AD requires cleaning and visually inspecting the M/R blades and, depending on the outcome of the inspection, repairing or replacing the M/R blades. This AD is prompted by a report of an M/R blade with a fatigue crack in the grip plate and doublers at the blade retention bolt hole. The actions of this AD are intended to correct an unsafe condition on these products.
Airworthiness Directives; Fokker Services B.V. Airplanes
Document Number: 2018-00656
Type: Rule
Date: 2018-01-17
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 Mark 0100 series airplanes. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition on these products, and doing the actions specified in those instructions. This AD was prompted by an erroneous radio altimeter reading, which caused certain systems to respond in a way that led to loss of speed. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Aerospace Welding Minneapolis, Inc., Mufflers
Document Number: 2018-00479
Type: Rule
Date: 2018-01-17
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Aerospace Welding Minneapolis, Inc. mufflers, part numbers A1754001-23 and A1754001-25, installed on airplanes. This AD was prompted by occurrences of cracks or broken welds in the connecting weld of the muffler body to muffler cuff that may allow carbon monoxide exhaust fumes into the cockpit heating system. This AD requires an inspection of the muffler for leaking to identify cracks and replacement of the muffler. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2018-00109
Type: Proposed Rule
Date: 2018-01-17
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposal to supersede Airworthiness Directive (AD) 2014-12-13, which applies to all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. The first SNPRM proposed to revise the proposal by expanding the inspection area, and terminating, rather than superseding, the requirements of AD 2014-12-13, after accomplishment of the initial inspections. This action proposes to again revise the proposal by requiring the installation of standard-size fasteners for a certain configuration. We are proposing this AD to address the unsafe condition on these products. Since these actions impose an additional burden over that proposed in the first SNPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
