Federal Aviation Administration July 25, 2014 – Federal Register Recent Federal Regulation Documents

Special Conditions: Airbus Model A350-900 Airplanes; Lateral-Trim Function Through Differential Flap Setting
Document Number: 2014-17578
Type: Rule
Date: 2014-07-25
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for Airbus Model A350-900 airplanes. These airplanes will have a novel or unusual design feature associated with a lateral-trim function that deploys flaps asymmetrically for airplane lateral-trim control. This function replaces the traditional method of providing airplane lateral trim over a small range through flap and aileron mechanical rigging. 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.
Special Conditions: Airbus Model A350-900 Airplanes; Isolation or Protection of the Aircraft Electronic System Security From Unauthorized Internal Access

Type: Rule
Date: 2014-07-25
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for Airbus Model A350-900 airplanes. These airplanes will have a novel or unusual design feature associated with airplane electronic system security protection or isolation from unauthorized internal access. 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.
Special Conditions: Airbus Model A350-900 Series Airplane; Electronic Flight-Control System: Lateral-Directional and Longitudinal Stability, and Low-Energy Awareness
Document Number: 2014-17575
Type: Rule
Date: 2014-07-25
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for Airbus Model A350-900 series airplanes. These airplanes will have a novel or unusual design feature associated with lateral- directional and longitudinal stability, and low-energy awareness. 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.
Special Conditions: Airbus A350-900 Airplane; Crashworthiness, Emergency Landing Conditions
Document Number: 2014-17574
Type: Rule
Date: 2014-07-25
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for Airbus Model A350-900 airplanes. These airplanes have a novel or unusual design feature associated with crashworthiness of carbon-fiber-reinforced plastic used in the construction of the fuselage. 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; Bombardier, Inc. Airplanes
Document Number: 2014-17550
Type: Proposed Rule
Date: 2014-07-25
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2013-16- 08 for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and Model CL-600-2D24 (Regional Jet Series 900) airplanes. Since we issued AD 2013-16-08, we have determined that a certain part was incorrectly identified in a certain section of that AD. This proposed AD would continue to require inspection of the MLG retraction actuator components; corrective actions if necessary; and, for certain retraction actuators, installation of a new jam nut. We are proposing this AD to prevent disconnection of the MLG retraction actuator, which could result in extension of the MLG without damping, and consequent structural damage and collapse of the MLG during landing.
Interpretation of the Special Rule for Model Aircraft
Document Number: 2014-17528
Type: Rule
Date: 2014-07-25
Agency: Federal Aviation Administration, Department of Transportation
The FAA is extending the comment period on its Interpretation of the Special Rule for Model Aircraft that was published on June 25, 2014.
Special Conditions: Learjet Inc., Model LJ-200-1A10 Airplane; Composite Fuselage In-Flight Fire/Flammability Resistance
Document Number: 2014-17518
Type: Rule
Date: 2014-07-25
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Learjet Inc. Model LJ-200-1A10 airplane. This airplane will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The fuselage of the Model LJ-200-1A10 will be made of composite materials rather than conventional aluminum, which may affect fire propagation during an in-flight fire. 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.
Special Conditions: Bombardier Aerospace, Models BD-500-1A10 and BD-500-1A11 Series Airplanes; Alternate Fuel Tank Structural Lightning Protection Requirements
Document Number: 2014-17517
Type: Proposed Rule
Date: 2014-07-25
Agency: Federal Aviation Administration, Department of Transportation
This action proposes special conditions for the Bombardier Aerospace Models BD-500-1A10 and BD-500-1A11 series airplanes. These airplanes will have a novel or unusual design feature that will incorporate a nitrogen generation system (NGS) for all fuel tanks that actively reduce flammability exposure within the fuel tanks significantly below that required by the fuel tank flammability regulations. Among other benefits, the NGS significantly reduces the potential for fuel vapor ignition caused by lightning strikes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed 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.
