Installed Systems and Equipment for Use by the Flightcrew
This rule amends design requirements in the airworthiness standards for transport category airplanes to minimize the occurrence of design-related flightcrew errors. The new design requirements will enable a flightcrew member to detect and manage his or her errors when the errors occur. Adopting this rule will eliminate regulatory differences between the airworthiness standards of the United States (U.S.) and those of the European Aviation Safety Agency (EASA) without affecting current industry design practices.
Notice of Intent To Release Certain Properties From All Terms, Conditions, Reservations and Restrictions of a Quitclaim Deed Agreement Between the City of Zephyrhills and the Federal Aviation Administration for the Zephyrhills Municipal Airport, Zephyrhills, FL
The FAA hereby provides notice of intent to release certain airport properties 33 acres at the Zephyrhills Municipal Airport, Zephyrhills, FL from the conditions, reservations, and restrictions as contained in a Quitclaim Deed agreement between the FAA and the City of Zephyrhills, dated May 15, 1947. The release of property will allow the City of Zephyrhills to dispose of the property for other than aeronautical purposes. The property is located on the southeast corner of airport property. The parcel is currently designated as non- aeronautical use. The property will be released of its federal obligations for municipal purposes. The fair market value of this parcel has been determined to be $500,000. Documents reflecting the Sponsor's request are available, by appointment only, for inspection at the Zephyrhills Municipal Airport and the FAA Airports District Office.
Notice of Termination of Environmental Impact Statement for the Friedman Memorial Replacement Airport, Hailey, ID
The Federal Aviation Administration (FAA) announces its decision to terminate the Environmental Impact Statement (EIS) for the Friedman Memorial Replacement Airport.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 727 airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the frame-to-floor beam attachment is subject to widespread fatigue damage (WFD). This proposed AD would require repetitive high frequency eddy current inspections for any crack of the frames at body station (STA) 188 through STA 344, and repair if necessary. We are proposing this AD to detect and correct fatigue cracking at the frame-to-floor beam attachment, on both the left- and right-sides, which could result in reduced structural integrity of the airplane, and decompression of the cabin.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200, -300 and -200 Freighter series airplanes, and Model A340-200, -300, -500, and -600 series airplanes. This proposed AD would require, for certain airplanes, revising the airplane flight manual (AFM) to advise the flight crew of emergency procedures for addressing Angle of Attack (AOA) sensor blockage. This proposed AD would also mandate replacing the AOA sensor conic plates with AOA sensor flat plates, which is a terminating action for the AFM revision. This proposed AD was prompted by a report that an airplane equipped with AOA sensors installed with conic plates recently experienced blockage of all sensors during climb, leading to autopilot disconnection and activation of the alpha protection (Alpha Prot) when Mach number was increased. We are proposing this AD to prevent reduced control of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 747 series airplanes. The existing AD currently requires inspection of the fuselage skin lap splice between body station (BS) 340 and BS 400 at stringers (S)-6L and S-6R, and repair, if necessary. Since we issued that AD, analysis results indicated that the protruding head fastener modification and related post-modification inspections currently required are not adequate to prevent cracking at the upper row of fasteners in the stringer 6 lap joint before the cracks reach a critical length. This proposed AD would add new repetitive inspections for cracking in the stringer 6 skin lap splice, which would terminate the existing inspections; and eventual modification of the lap splice, which would terminate the repetitive inspections; post-modification inspections; and corrective actions if necessary. This proposed AD would also add airplanes to the applicability. We are proposing this AD to detect and correct cracking at the upper row of fasteners in the stringer(s) 6 lap joint, which could result in a sudden loss of cabin pressurization and the inability of the fuselage to withstand failsafe loads.
Special Conditions: Airbus, Model A340-600 Series Airplanes; Lower Deck Crew Rest Compartments
These special conditions are issued for the Airbus Model A340 series airplanes. These airplanes, as modified by Flight Structures, Inc., will have a novel or unusual design feature associated with the installation of lower deck crew rest (LDCR) compartments. The LDCR compartment is novel in terms of part 25 in that it will be located under the passenger cabin floor in the aft cargo compartment of Airbus Model A340-200 series airplanes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Proposed Standard Operating Procedure (SOP) of the Aircraft Certification Service (AIR) Project Prioritization and Resource Management
This notice announces the availability of, and request for public comments on, the Aircraft Certification Service (AIR) standard operating procedure (SOP) describing the process used to prioritize certification projects and manage certification project resources when local resources are not available.
