Federal Aviation Administration June 8, 2006 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Boeing Model 707-100 Long Body, -100B Long Body, -100B Short Body, -E3F, -300, -300B, and -300C Series Airplanes; Model 727-100 and -200 Series Airplanes; Model 737-200, -200C, -300, -400, and -500 Series Airplanes; Model 747-100B, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747SR, and 747SP Series Airplanes; Model 757-200 and 757-200PF Series Airplanes; and Model 767-200 and -300 Series Airplanes; Equipped With Observer or Attendant Seats
Document Number: E6-8901
Type: Proposed Rule
Date: 2006-06-08
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing airplanes. The existing AD currently requires inspection of the attachment of the shoulder restraint harness to the mounting bracket on certain observer and attendant seats to determine if a C-clip is used in the attachment, and corrective action, if necessary. This proposed AD would remove certain airplanes from the applicability and add others. This proposed AD results from the determination that some airplanes had been inadvertently included in or excluded from the applicability of the existing AD and that certain additional new airplanes are now subject to the identified unsafe condition. We are proposing this AD to prevent detachment of the shoulder restraint harness of the attendant or observer seat from its mounting bracket during service, which could result in injury to the occupant of the seat.
Airworthiness Directives; Airbus Model A300 Airplanes, Equipped With General Electric CF6-50 Series Engines
Document Number: E6-8900
Type: Proposed Rule
Date: 2006-06-08
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A300 airplanes. This proposed AD would require modifying the airplane and the engine/nacelle to install a third line of defense against inadvertent deployment of the thrust reverser in flight. This proposed AD would also require two other actions that must be accomplished before or concurrently with the modification: installing a structural change in the fan cowl to avoid interference; and installing a dedicated, shielded electrical circuit. This proposed AD results from a report that the manufacturer has developed a third line of defense against the inadvertent deployment of the thrust reverser of A300 airplanes that are equipped with General Electric CF6- 50 series engines (in accordance with FAA guidelines). We are proposing this AD to prevent inadvertent deployment of the thrust reverser in flight, which could result in reduced controllability of the airplane.
Airworthiness Directives; McDonnell Douglas Model 717-200 Airplanes
Document Number: E6-8899
Type: Proposed Rule
Date: 2006-06-08
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This proposed AD would require modifying the fuel boost pump container of the center tank. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent exposing the fuel pump container vapor area to electrical arcing during a fuel pump motor case or connector burn through, which could result in a fuel tank explosion.
Airworthiness Directives; Bombardier Model DHC-8-100, DHC-8-200, DHC-8-300, and DHC-8-400 Series Airplanes
Document Number: E6-8898
Type: Proposed Rule
Date: 2006-06-08
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC-8-100, DHC-8-200, DHC-8-300, and DHC- 8-400 series airplanes. This proposed AD would require inspecting the left and right control column torque tube assemblies to determine the type of rivets installed and replacing incorrect or indeterminate type rivets with the correct type rivets. This proposed AD results from a report that incorrect rivets having lower than required strength were installed on the control column torque tube during production. We are proposing this AD to prevent shear failure of control column torque tube rivets, which could cause unexpected decoupling of the elevators and large unwanted deflection of the free elevator, and consequent reduced controllability of the airplane.
Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Airplanes
Document Number: E6-8897
Type: Proposed Rule
Date: 2006-06-08
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This proposed AD would require a one-time detailed inspection to detect corrosion on the wing rear spar lower girder, and related investigative and applicable corrective actions if necessary. This proposed AD results from reports of corrosion of the wing rear spar lower girder between wing station (STA) 8700 and wing STA 9200. We are proposing this AD to detect and correct corrosion of the wing rear spar lower girder, which could result in reduced structural integrity of the wing rear spar.
