High Density Airports; Notice of Extension of the Lottery Allocation and Amended Policy for Reallocation Procedures for Slot Exemptions at LaGuardia Airport
The FAA is extending by fourteen months the current allocation of slot exemptions at LaGuardia Airport (LaGuardia) through December 31, 2006. This action maintains the current limit on scheduled operations at LaGuardia pending the adoption of a long-term solution for congestion management and the expiration of the High Density Traffic Airports Rule (High Density Rule) at LaGuardia on January 1, 2007. We also are amending the lottery reallocation procedures at LaGuardia in response to a petition submitted by Northwest Airlines, Inc. (Northwest). Air carriers that do not currently serve small hub/ non-hub airports from LaGuardia can now participate in any reallocation of AIR-21 slot exemptions that are returned to the FAA or become available through non-use.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
This document revises an earlier proposed airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, that would have required performing repetitive inspections of the electrical harnesses of the spoiler and the brake pressure sensor unit on both sides of the wing root to detect any chafing or wire damage, and repairing or replacing any damaged or chafed harness or wire with a new harness, as applicable. This new action revises the proposed rule by expanding the applicability to include additional airplanes, deleting the repetitive inspections, and by adding a terminating modification for the one-time inspection. The actions specified by this new proposed AD are intended to detect and correct chafing of the electrical cables of the spoiler and brake pressure sensor unit on both sides of the wing root, which could result in loss of flight control system and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Boeing Model 737-300, -400, and -500 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-300, -400, and -500 series airplanes. This AD requires repetitive inspections for cracking of the crown area of the fuselage skin, and corrective actions if necessary. This AD is prompted by a Model 737 fuselage structure test and fatigue analysis that indicate fuselage skin cracking could occur between 21,000 and 42,000 total flight cycles. We are issuing this AD to detect and correct fatigue cracking of the fuselage skin, which could cause the fuselage skin to fracture and fail, and could result in rapid decompression of the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-9-10 Series Airplanes; Model DC-9-20 Series Airplanes; Model DC-9-30 Series Airplanes; Model DC-9-40 Series Airplanes; Model DC-9-50 Series Airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) Airplanes; and Model MD-88 Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain SAFT America Inc. part number (P/N) 021929-000 (McDonnell Douglas P/N 43B034LB02) and P/N 021904-000 (McDonnell Douglas P/N 43B034LB03) nickel cadmium batteries. That AD currently requires replacing all battery terminal screws, verifying that the battery contains design specification cells, and replacing the cells if the battery contains non-design specification cells. This new AD requires an inspection for certain nickel cadmium batteries and, if necessary, replacing battery terminal screws with new hex head bolts and adding shims. This AD is prompted by a report of battery screws shearing off while under normal torque loads. We are issuing this AD to prevent internal shorting, arcing, and loss of emergency battery power due to failed battery screws, which could result in loss of emergency power to electrical flight components or other emergency power systems required in the event of loss of the aircraft primary power source.
Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes; 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
The FAA is adopting a new airworthiness directive (AD) for certain Airbus models, as specified above. This AD requires installing safety signs on all passenger/crew doors, emergency exit doors, and cargo compartment doors. This AD is prompted by a report of injuries occurring on in-service airplanes when crewmembers forcibly initiated opening of passenger/crew doors against residual pressure causing the doors to rapidly open. We are issuing this AD to ensure that crewmembers are informed of the risks associated with forcibly opening passenger/crew, emergency exit, and cargo doors before an airplane is fully depressurized, which will prevent injury to crewmembers, and subsequent damage to the airplane caused by the rapid opening of the door.
Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777-200 and -300 series airplanes. This AD requires a one-time inspection of the clevis end of the vertical tie rods that support the center stowage bins to measure the exposed thread, installation of placards that advise of weight limits for certain electrical racks, a one-time inspection and records check to determine the amount of weight currently installed in those electrical racks, corrective actions, and replacement of the vertical tie rods for the center stowage bins or electrical racks with new improved tie rods, as applicable. The actions specified by this AD are intended to prevent failure of the vertical tie rods supporting certain electrical racks and the center stowage bins, which could cause the center stowage bins or electrical racks to fall onto passenger seats below during an emergency landing, impeding an emergency evacuation or injuring passengers. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This AD requires inspecting for the installation of the tie plate for the wire bundles routed from lower section 41 into the center control stand in the flight deck; inspecting for any wire chafing or damage and repair if necessary; and installing a tie plate if necessary. This AD is prompted by a report of missing tie plates for the wire bundles. We are issuing this AD to prevent wire chafing, which could result in the loss of flight control, communication, navigation, and engine fire control systems. Loss of these systems could consequently result in a significant reduction of safety margins, an increase in flight crew workload, and in the case where loss of engine fire control is combined with an engine fire, could result in an uncontrollable fire.
Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300 B2 and B4 series airplanes. This AD requires modifying the wiring of the autopilot pitch torque limiter switch. This AD is prompted by several reports of pitch trim disconnect caused by insufficient length in the wiring to the pitch torque limiter lever. We are issuing this AD to prevent possible trim loss when the flightcrew tries to override the autopilot pitch control, which could result in uncontrolled flight of the airplane.
Airworthiness Directives; Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes. This AD requires a detailed inspection to determine the presence of incorrectly installed bushings in the attachment holes of the reinforcing strap of the left- and right-hand wings' lower skin, and corrective actions if necessary. This AD is prompted by a report that bushings were installed in accordance with improper procedures in the structural repair manual. We are issuing this AD to detect and correct improperly installed bushings, which could result in reduced tensile strength of the reinforcing strap of the wing's lower skin, and consequently a reduction of the structural capability of the wing and possible wing failure.
Airworthiness Directives; Boeing Model 737-100, -200, and -200C Series Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 737-100, -200, and -200C series airplanes, that requires repetitive inspections to detect discrepancies of certain fuselage skin panels located just aft of the wheel well, and repair if necessary. The actions specified by this AD are intended to detect and correct fatigue cracking of the skin panels, which could cause rapid decompression of the airplane. This action is intended to address the identified unsafe condition.
