Federal Aviation Administration February 28, 2014 – Federal Register Recent Federal Regulation Documents

We propose to supersede Airworthiness Directive (AD) 2000-17- 03 that applies to all Fokker Services B.V. Model F.28 Mark 0100 airplanes. AD 2000-17-03 currently requires a one-time visual inspection and repetitive eddy current and dye penetrant inspections of the nose landing gear (NLG) main fitting to detect cracking of the NLG main fitting subassembly, and corrective actions if necessary. Since we issued AD 2000-17-03, we were advised that replacement of certain nose landing gear (NLG) units eliminates the need for repetitive inspections. This proposed AD would retain existing requirements, require installation a new part number NLG unit that would terminate the repetitive inspections, and add airplanes to the applicability. We are proposing this AD to prevent cracking of the NLG main fitting, which could lead to collapse of the NLG during takeoff and landing, and possible injury to the flight crew and passengers.

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4-601, B4-603, B4-620, B4-622, -B4-605R, B4- 622R, -F4-605R, F4-622R, and -C4-605R Variant F airplanes; and Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes. This proposed AD was prompted by a report of inner skin disbonding damage on a rudder. This proposed AD would require repetitive ultrasonic inspections for disbonding of certain rudders; an elasticity of laminate checker inspection; a woodpecker or tap test inspection; venting the core, if necessary; and repairing, if necessary. We are proposing this AD to detect and correct rudder disbonding, which could affect the structural integrity of the rudder.

This action establishes Class E airspace at Eagle Airport, Eagle, AK. Controlled airspace is necessary to accommodate aircraft using the new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at the airport. This action enhances the safety and management of aircraft operations at the airport. This action also makes a minor correction to the airspace's vertical dimensions, and corrects the Docket Numbers in the Addresses section.
