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)
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A300-600 airplanes. This proposed AD would require an inspection to determine if certain spoiler actuators having certain part numbers are installed, and eventual replacement of all affected actuators. This proposed AD results from failure of a distribution block, which was detected during fatigue qualification tests of certain spoiler actuators. We are proposing this AD to prevent failure of the distribution block, which could result in leakage of the hydraulic fluid that supplies those actuators. This failure could cause failure of one of the three spoiler actuators and the associated hydraulic circuits, which could result in loss of those hydraulic circuits and consequent reduced controllability of the airplane.
Airworthiness Directives; Airbus Model A330 Airplanes and Model A340-200 and -300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330 airplanes and Model A340-200 and -300 series airplanes. This AD requires repetitive detailed inspections for cracking in the aft web of support rib 6 between certain bottom skin stringers on both wings; high frequency eddy current inspections for cracking of the attachment holes of the fuel pipes, and repair if necessary. This AD also provides for an optional modification, which extends a certain inspection threshold, and mandates, for certain airplanes, a new modification of support rib 6 on both wings, which ends the repetitive inspection requirement. This AD results from a report of significant cracking found in the aft web of support rib 6 on both wings. We are issuing this AD to prevent cracking in the aft web of support rib 6, which could result in overloading of adjacent ribs and the surrounding wing structure and consequent reduced structural integrity of the wing.
Airworthiness Directives; Boeing Model 747 Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all Boeing Model 747 series airplanes. That AD currently requires repetitive inspections for cracking of the top and side panel webs and panel stiffeners of the nose wheel well (NWW), and corrective actions if necessary. This new AD reduces the interval for certain repetitive inspections and removes a certain optional inspection. This new AD also requires replacing the NWW side and top panels with new panels, which terminates the repetitive inspections. This AD results from the development of a new modification. We are issuing this AD to prevent fatigue cracks in the top and side panel webs and stiffeners of the NWW, which could compromise the structural integrity of the NWW and could lead to the rapid decompression of the airplane.
Establishment of Class D Airspace; Ft. Riley, KS
This notice amends Part 71 of the Federal Aviation Regulations (14 CFR part 71) by establishing a Class D airspace area extending upward from the surface to and including 3,600 feet above sea level within a 3.7-mile radius of Fort Riley, Marshall Army Airfield, KS. The establishment of an air traffic control tower has made this action necessary.
Eighth Meeting: FTCA Special Committee 203/Minimum Performance Standards for Unmanned Aircraft Systems and Unmanned Aircraft
The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 203, Minimum Performance Standards for Unmanned Aircraft Systems and Unmanned Aircraft.
Notice of Passenger Facility Charge (PFC) Approvals and Disapprovals.
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.
