Federal Aviation Administration October 18, 2012 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; EADS CASA (Type Certificate Previously Held by Construcciones Aeronáuticas, S.A.) Airplanes
Document Number: 2012-25673
Type: Proposed Rule
Date: 2012-10-18
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all EADS CASA (Type Certificate Previously Held by Construcciones Aeron[aacute]uticas, S.A.) Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes. This proposed AD was prompted by reports of incorrect electrical polarity connections on engine fire extinguishing discharge cartridges. This proposed AD would require a one-time inspection to identify the correct polarity for each pair of electrical connectors on each engine fire extinguisher cartridge, and repair if necessary. We are proposing this AD to detect and correct incorrect polarity connections, which could prevent the actuation of the discharge cartridge in case of automatic fire detection or manual initiation during a potential engine fire, and could result in damage to the airplane and injury to passengers.
Special Conditions: Airbus Model A318, A319, A320, and A321 Series Airplanes; Design Roll Maneuver Conditions
Document Number: 2012-25606
Type: Rule
Date: 2012-10-18
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Airbus Model A318, A319, and A320 series airplanes with modification 160500 and Model A321 series airplanes with modification 160023 (Sharklet). These airplanes will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These design features include electronic flight controls that affect maneuvering. 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 A318, A319, A320, and A321 Series Airplanes; Design Dive Speed

These special conditions are issued for the Airbus Model A318, A319, and A320 series airplanes with modification 160500 and Model A321 series airplanes with modification 160023 (Sharklet). These airplanes will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These design features include a high-speed protection system. 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 A318, A319, A320, and A321 Series Airplanes; Interaction of Systems and Structures
Document Number: 2012-25604
Type: Rule

These special conditions are issued for the Airbus Model A318, A319, and A320 series airplanes with modification 160500 and Model A321 series airplanes with modification 160023 (Sharklet). These airplanes will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The design features are associated with the systems that affect the structural performance of the airplane. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. 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.
