Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Airplanes
Document Number: E6-11806
Type: Proposed Rule
Date: 2006-07-25
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. This proposed AD would require modifying the nose landing gear. This proposed AD results from reports of loss of the nose wheel assembly. We are proposing this AD to prevent the nose wheel nut from loosening, and consequently, the nose wheel assembly detaching from the airplane; and to prevent the nose wheel clamping loads from applying to the machined radius at the root of the stub axle, which could result in damage to the nose landing gear.
Airworthiness Directives; McDonnell Douglas Model DC-8-55, DC-8F-54, and DC-8F-55 Airplanes; and DC-8-60, DC-8-70, DC-8-60F, and DC-8-70F Series Airplanes
Document Number: E6-11805
Type: Proposed Rule
Date: 2006-07-25
Agency: Federal Aviation Administration, Department of Transportation
This document revises an earlier proposed airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-8 airplanes. That proposed AD would have required a one-time inspection for cracks of the aft fuselage skin panel at the longeron 28 skin splice; repair of any cracks detected; and reporting of the findings of the inspection to the manufacturer. This new action revises the proposed AD by removing airplanes from the applicability; and adds repetitive inspections for cracks in the same area, a one-time inspection for previous repairs, and repair if necessary. This new action also would require reporting the inspection findings to the manufacturer, and would provide optional actions for extending the repetitive inspection intervals. The requirements proposed by this new action are intended to detect and correct cracks in the aft fuselage skin at the longeron 28 skin splice, which could lead to loss of structural integrity of the aft fuselage, resulting in rapid decompression of the airplane. This action is intended to address the identified unsafe condition.
Performance and Handling Qualities Requirements for Rotorcraft
Document Number: E6-11726
Type: Proposed Rule
Date: 2006-07-25
Agency: Federal Aviation Administration, Department of Transportation
The FAA is proposing new and revised airworthiness standards for normal and transport category rotorcraft due to technological advances in design and operational trends in normal and transport rotorcraft performance and handling qualities. The changes would enhance the safety standards for performance and handling qualities to reflect the evolution of rotorcraft capabilities.
Airworthiness Directives; Airbus Model A300 Airplanes; Model A310 Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
Document Number: E6-11713
Type: Rule
Date: 2006-07-25
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 airplanes and Model A310 airplanes, and for certain Airbus Model A300-600 series airplanes. This AD requires an inspection of the wing and center fuel tanks to determine if certain P-clips are installed and corrective action if necessary. This AD also requires an inspection of electrical bonding points of certain equipment in the center fuel tank for the presence of a blue coat and related investigative and corrective actions if necessary. This AD also requires installation of new bonding leads and electrical bonding points on certain equipment in the wing, center, and trim fuel tanks, as necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to ensure continuous electrical bonding protection of equipment in the wing, center, and trim fuel tanks and to prevent damage to wiring in the wing and center fuel tanks, due to failed P-clips used for retaining the wiring and pipes, which could result in a possible fuel ignition source in the fuel tanks.
Airworthiness Directives; Construcciones Aeronauticas, S.A. (CASA), Model C-212-CC Airplanes
Document Number: E6-11706
Type: Rule
Date: 2006-07-25
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain CASA Model C-212-CC airplanes. This AD restricts the operation of the airplane to carrying either passengers or cargo (but not both) in the same compartment, unless the airplane is modified to include an approved protective liner between the passengers and the cargo. This AD results from our determination that affected airplanes, when carrying both cargo and passengers in the same compartment, cannot achieve the required level of performance. We are issuing this AD to prevent a hazardous quantity of smoke, flames, and/or fire extinguishing agent from the cargo compartment from entering a compartment occupied by passengers or crew.

Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Airbus Model A310-200 and -300 Series Airplanes
Document Number: E6-11700
Type: Rule
Date: 2006-07-25
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600 series airplanes); and Model A310-200 and -300 series airplanes. This AD requires a one-time inspection of the trimmable horizontal stabilizer actuator (THSA), corrective actions if necessary, and follow-on repetitive tasks. This AD results from reports of THSAs that have reached their design operational life. We are issuing this AD to extend the operational life of the THSA to prevent a possible failure of high- time THSAs, which could result in reduced controllability of the airplane.
