Federal Aviation Administration August 8, 2005 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A300 B2 and B4 series airplanes. This proposed AD would require an inspection to determine the part number of all angle of attack (AOA) sensors, and repetitive replacement of the AOA sensors with new or overhauled AOA sensors if necessary. This proposed AD would also provide an optional terminating action for the repetitive replacements. This proposed AD is prompted by reports of several false stall warnings associated with stick-shaker activation, occurring during take-off. We are proposing this AD to prevent false stall warnings associated with stick-shaker activation, which could result in increased pilot workload as the pilot tries to determine the cause of the stall warning and possible reduction in the pilot's ability to control the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4-620, A310-304, A310-324, and A310-325 airplanes. This proposed AD would require installing fused adaptors between the external wiring harness and the in-tank wiring at the connectors on the fuel tank wall of the auxiliary center tank (ACT). This proposed AD is prompted by the results of fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent an ignition source in the ACT, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for all Gulfstream Model GV and certain Model GV-SP series airplanes. This proposed AD would require a one-time inspection of the left and right aileron and elevator actuators to determine the part and serial numbers of each actuator, repetitive inspections of suspect actuators to detect broken damper shafts, and replacement of any actuator having a broken damper shaft. This proposed AD would also require that operators report any broken damper shaft they find to the FAA. This proposed AD also would provide an optional terminating action for the repetitive inspection requirements of this proposed AD. This proposed AD is prompted by reports of broken or cracked damper shafts within the aileron and elevator actuator assemblies. We are proposing this AD to detect and correct broken damper shafts, which could result in locking of an aileron or elevator actuator (hard-over condition), which would activate the hard-over protection system (HOPS), resulting in increased pilot workload and consequent reduced controllability of the airplane.

This action proposes to establish Class C airspace at the Orlando Sanford International Airport (SFB), FL; revoke the existing Sanford, FL, Class D airspace area; and modify the existing Orlando International Airport (MCO), FL, Class B airspace area. The FAA is proposing this action to improve the flow of air traffic, enhance safety, and reduce the potential for midair collision in the Orlando, FL, terminal area.

This action revises Very High Frequency Omni-directional Range (VOR) Federal Airways V-9, V-50, V-67, V-69, V-129, V-173 and V-233; and Jet Routes J-35, J-80, J-101 and J-137 over the Springfield, IL area. The FAA is taking this action due to the relocation of the Capital VOR/Tactical Air Navigation (VORTAC) and the renaming of the ``Capital VORTAC'' to the ``Spinner VORTAC'' to enhance the management of aircraft operations over the Springfield, IL area.

The FAA publishes a monthly notice, as appropriate, of PFC approvals and disapprovals under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub. L. 101-508) and part 158 of the Federal Aviation Regulations (14 CFR part 158). This notice is published pursuant to paragraph d of Sec. 158.29.
