Federal Aviation Administration April 30, 2015 – Federal Register Recent Federal Regulation Documents

Special Conditions: L-3 Communications Integrated Systems, Boeing Model 747-8 Series Airplanes; Therapeutic Oxygen for Medical Use
Document Number: 2015-10103
Type: Proposed Rule
Date: 2015-04-30
Agency: Federal Aviation Administration, Department of Transportation
This action proposes special conditions for the Boeing Model 747-8 series airplanes. This airplane, as modified by L-3 Communications Integrated Systems (L-3), will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is therapeutic oxygen for medical use installed in an executive-interior airplane. 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.
Special Conditions: Bombardier Inc. Model BD-700-2A12 and BD-700-2A13 Airplanes; Design Roll-Maneuver Condition
Document Number: 2015-10102
Type: Rule
Date: 2015-04-30
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Bombardier Inc. Model BD-700-2A12 and BD-700-2A13 airplanes. These airplanes will have a novel or unusual design feature associated with an electronic flight- control system that provides roll control of the airplanes through pilot inputs to the flight computers. 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 A319-151n/171n, A320-251n/271n, and A321-251n/271n (SAneo) Series Airplanes; Transient Engine-Failure Loads
Document Number: 2015-10098
Type: Rule
Date: 2015-04-30
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for Airbus Model A319- 151n/171n, A320-251n/271n, and A321-251n/271n (collectively known as Single Aisle new engine option (SA neo)) series airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is a new generation of high-bypass engines, and the potential loads resulting from extreme engine-failure conditions. 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.
Notice of a Land Release Affecting the Federal Grant Assurance Obligations at Ryan Field Airport, Tucson, Pima County, Arizona
Document Number: 2015-10097
Type: Notice
Date: 2015-04-30
Agency: Federal Aviation Administration, Department of Transportation
The Federal Aviation Administration (FAA) proposes to rule and invites public comment on the application for a land release of approximately 5.12 acres of airport property, along with an easement over 2.09 acres, at Ryan Field Airport, Tucson, Pima County, Arizona from the airport use provisions of the Grant Agreement Assurances since the land is not needed for airport purposes. The property will be used by the Arizona Department of Transportation to widen State Route 86 that is located along the southern edge of the airport. The airport will be compensated for the fair market value of the released property. The use of the land for a roadway represents a compatible land use that will not interfere with the airport or its operation, thereby protecting the interests of civil aviation.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2015-09813
Type: Rule
Date: 2015-04-30
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by a determination that without an effective maintenance task to maintain the airplane's inherent level of safety, there is a potential that a dormant failure of the alternate release system of the landing gear could occur. This AD requires revising the maintenance or inspection program, as applicable, to incorporate a maintenance task for an operational check of the electro- mechanical actuator and release mechanism of the alternate extension system for the nose landing gear and main landing gear. We are issuing this AD to prevent failure of the alternate release system of the landing gear, which could prevent the landing gear from extending during a failure of the normal landing gear extension system.
Airworthiness Directives; Airbus Airplanes
Document Number: 2015-09811
Type: Rule
Date: 2015-04-30
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Airbus Model A318-111 and -112 airplanes and Model A319, A320, and A321 series airplanes. This AD was prompted by reports of cracks on the forward corner fittings of engine pylon aft secondary structures. This AD requires repetitive inspections of certain forward corner fittings of the pylon aft secondary structures, and corrective actions if necessary. This AD also provides optional terminating action for the repetitive inspections. We are issuing this AD to detect and correct detachment of the lower fairing attachment and/or loss of the aft fixed fairing with the movable fairing from the airplane in flight, which could result in damage to the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2015-09805
Type: Rule
Date: 2015-04-30
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600 and -700 series airplanes. This AD was prompted by reports of cracking in the body station (STA) 727 bulkhead lower frame. This AD requires a detailed and open hole high frequency eddy current (HFEC) inspection of the left- and right-side lower frame webs and inner chords for cracking, and corrective actions and preventative modifications if necessary. This AD also provides for optional terminating action of the repetitive inspections, under certain conditions. We are issuing this AD to detect and correct cracking in a bulkhead lower frame web and inner chord, which could result in a severed frame and induced skin cracks, and could lead to rapid decompression of the fuselage.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2015-07802
Type: Rule
Date: 2015-04-30
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This AD was prompted by a determination that the forward lugs of the flap hinge box might not conform to engineering drawings, which could result in premature fatigue cracking. This AD requires revising the maintenance or inspection program to include new airworthiness limitations tasks; and measuring the forward lug edge distance of each flap hinge box, inspecting for cracking and damage (i.e., deformation or bearing failure) of the forward lug edge of each flap hinge box, and repairing any cracking or damage if necessary. We are issuing this AD to detect and correct non-conforming flap hinge box forward lugs, which could result in failure of the lugs and detachment of the flap hinge box and consequent detachment of the flap surface.
