Federal Aviation Administration March 29, 2006 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for all DORNIER LUFTFAHRT GmbH (DORNIER) Models 228-100, 228-101, 228-200, 228- 201, 228-202, and 228-212 airplanes. This proposed AD would require you to repetitively inspect the wiring in the flight deck overhead panels (locations 5VE and 6VE) for chafing and damage and repair any chafed or damaged wires. Regardless of the results of each inspection, this proposed AD would require you to assure correct installation of the wiring in the flight deck overhead panels by reattaching or replacing the wire tie attachment holders and securing any loose wires to the wire tie attachment holders with plastic wire ties. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are proposing this AD to detect, correct, and prevent chafed or damaged wires in the flight deck overhead panels, which could result in short-circuiting of related wiring. This condition could lead to electrical failure of affected systems and potential fire in the flight deck.

This notice proposes special conditions for the Airbus A380- 800 airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. Many of these novel or unusual design features are associated with the complex systems and the configuration of the airplane, including its full- length double deck. For these design features, the applicable airworthiness regulations do not contain adequate or appropriate safety standards for design roll maneuvers. 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. Additional special conditions will be issued for other novel or unusual design features of the Airbus Model A380-800 airplane.

This document makes a correction to Airworthiness Directive (AD) 2005-13-09, which published in the Federal Register on August 23, 2005 (70 FR 49184), and applies to certain GROB-WERKE Model G120A airplanes. AD 2005-13-09 requires replacement of the main landing gear (MLG) up-lock hook assembly. Current language in paragraph (e)(2) of AD 2005-13-09 incorrectly references the MLG up-lock assembly as ``elevator and aileron hinge pins.'' This AD corrects that paragraph to reference the appropriate part number MLG up-lock hook assembly.
