Federal Aviation Administration May 30, 2007 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Pilatus Aircraft Ltd. Model PC-6 Series Airplanes
Document Number: E7-10315
Type: Proposed Rule
Date: 2007-05-30
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Revision to Class E Airspace; Laramie, WY
Document Number: E7-10256
Type: Rule
Date: 2007-05-30
Agency: Federal Aviation Administration, Department of Transportation
This final rule will revise the Class E airspace at Laramie, WY. Additional controlled airspace is necessary for the safety of aircraft executing an instrument approach procedure (IAP), and executing a new holding pattern published at Laramie Regional Airport, Laramie, WY. Additionally, this action reflects a change in the airport name from General Brees Field to Laramie Regional Airport.
Airworthiness Directives; McDonnell Douglas Model MD-11 and MD-11F Airplanes
Document Number: E7-10111
Type: Rule
Date: 2007-05-30
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all McDonnell Douglas Model MD-11 and MD-11F airplanes. This AD requires installing bracket assemblies and jumper wires in the center main wheel well to improve the bonding path between the structure (wall) of the lower auxiliary fuel tank and its internal fuel pumps; measuring the electrical resistance between the fuel pump housings and the fuel tank structure; and doing corrective actions if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to detect and correct an inadequate bond between the internal fuel pump housings and the structure of the lower auxiliary fuel tank. This condition, if not corrected, could fail to meet fault current requirements and result in a potential ignition source that, in combination with flammable fuel vapors, could cause a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) Airplanes, Model DC-10-40 and DC-10-40F Airplanes, and Model MD-10-30F Airplanes
Document Number: E7-10110
Type: Rule
Date: 2007-05-30
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-10-30 and DC-10-30F (KC-10A and KDC- 10) airplanes, Model DC-10-40 and DC-10-40F airplanes, and Model MD-10- 30F airplanes. This AD requires installing bracket assemblies and jumper wires in the center main wheel well to improve the bonding path between the structure (wall) of the lower auxiliary fuel tank and its internal fuel pumps; measuring the electrical resistance between the fuel pump housings and the fuel tank structure; and doing corrective actions if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to detect and correct an inadequate bond between the internal fuel pump housings and the structure of the lower auxiliary fuel tank. This condition, if not corrected, could fail to meet fault current requirements and result in a potential ignition source that, in combination with flammable fuel vapors, could cause a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ Airplanes
Document Number: E7-10108
Type: Rule

Agency: Federal Aviation Administration, Department of Transportation

This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product.

Airworthiness Directives; Airbus Model A310 Series Airplanes
Document Number: E7-10028
Type: Rule
Date: 2007-05-30
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD) that applies to all Airbus Model A310 series airplanes. That AD currently requires inspections of the lower door surrounding structure to detect cracks and corrosion; inspections to detect cracking of the holes of the corner doublers, the fail-safe ring, and the door frames of the door structures; and repair if necessary. That AD also currently provides for optional terminating action for certain inspections. This new AD retains all requirements of the existing AD, mandates the previously optional terminating action, and reduces the applicability of the existing AD. This AD results from a determination that further rulemaking is necessary to improve the fatigue behavior of the cabin door surroundings. We are issuing this AD to prevent corrosion between the scuff plates at exit and cargo doors and fatigue cracks originating from certain fastener holes located in adjacent structure, which could result in reduced structural integrity of the door surroundings.
