Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2014-04568
Type: Proposed Rule
Date: 2014-03-03
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for The Boeing Company Model airplanes equipped with Rolls-Royce Trent 800 series engines. This proposed AD was prompted by reports of in-flight separation of the aft plug from the forward plug, which are the two parts of the turbine exhaust plug assembly. This proposed AD would require installation of a serviceable turbine exhaust plug assembly (for certain airplanes), and a general visual inspection (for certain airplanes) to determine the diameter of the bolt used at the forward and aft plug interface, and applicable corrective actions. We are proposing this AD to prevent separation of the forward plug from the aft plug of the turbine exhaust plug assembly, which could result in parts departing the airplane and hitting the empennage or hitting a person on the ground, and destabilizing the airplane during a critical flight phase; parts remaining on a runway could cause damage to another airplane.
Special Conditions: Embraer S.A., Model ERJ-170 Airplanes; Seats With Large, Non-Traditional, Non-Metallic Panels
Document Number: 2014-04559
Type: Rule
Date: 2014-03-03
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for Embraer Model ERJ-170 airplanes. This airplane will have a novel or unusual design feature associated with interior arrangements that include passenger seats that incorporate non-traditional, large, non-metallic panels in lieu of the traditional metal frame covered by fabric. 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; Alpha Aviation Concept Limited Airplanes
Document Number: 2014-04549
Type: Proposed Rule
Date: 2014-03-03
Agency: Federal Aviation Administration, Department of Transportation

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 the metal screen shield over the ignition switch may ground out the ignition terminals. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
Document Number: 2014-04501
Type: Proposed Rule
Date: 2014-03-03
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede airworthiness directive (AD) 2008-14- 17, for certain Airbus Model A330-200 and A340-300 series airplanes. AD 2008-14-17 currently requires a high frequency eddy current (HFEC) inspection, corrective actions if necessary, and modifications. Since we issued AD 2008-14-17, it has been determined from a fatigue and damage tolerance evaluation that the compliance time needs to be revised. This proposed AD would require the same actions as those required by AD 2008-14-17, but with a reduced compliance time. We are proposing this AD to detect and correct damage of the upper shell structure at the skin and frame interface, which could result in reduced structural integrity of the airframe.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2014-04500
Type: Proposed Rule
Date: 2014-03-03
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 reports in which a single, undetected, erroneous radio altimeter output caused the autothrottle to enter landing flare retard mode prematurely on approach. This proposed AD would require removing certain autothrottle computers and installing a new or reworked autothrottle computer. We are proposing this AD to prevent a single, undetected, erroneous radio altimeter output from causing premature autothrottle landing flare retard and subsequent loss of automatic speed control, which could result in loss of control of the airplane.
Approval and Promulgation of State Implementation Plans: Alaska; Anchorage Carbon Monoxide Limited Maintenance Plan and State Implementation Plan Revisions
Document Number: 2014-04452
Type: Rule
Date: 2014-03-03
Agency: Environmental Protection Agency
The State of Alaska (the State) submitted two State Implementation Plan (SIP) revisions to the Anchorage Transportation Control Program, Anchorage Carbon Monoxide (CO) Maintenance Plan. On September 20, 2011, the State submitted a SIP revision (2011 Submittal) that updated Anchorage's CO motor vehicle emissions budget (MVEB) in the Anchorage CO maintenance area using the EPA's Motor Vehicle Emission Simulator (MOVES) model.
