Federal Aviation Administration September 30, 2005 – Federal Register Recent Federal Regulation Documents

The FAA recently issued a letter responding to a request from the Regional Airlines Association (RAA) for a blanket waiver of the minimum slot usage requirement for all slots at the three High Density Traffic Airports. The text of that letter is set forth in this notice.

The FAA is issuing this notice to advise the public that the FAA's Record of Decision (ROD), resulting from an Environmental Impact Statement (EIS) prepared by the Federal Highway Administration (FHWA) for its I-49 Connector Highway Project (State Project No. 700-24-0073 and Federal Aid Project No. DE-0009 (802) through Lafeyette, Louisiana.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Cessna Model 500, 550, S550, 560, 560XL, and 750 airplanes. This proposed AD would require installing identification sleeves on the wires for the positive and negative terminal studs of the engine and/or auxiliary power unit (APU) fire extinguishing bottles, as applicable, and re-connecting the wires to the correct terminal studs. This proposed AD results from a report of mis-wired fire extinguishing bottles. We are proposing this AD to ensure that the fire extinguishing bottles are activated in the event of an engine or APU fire, and that flammable fluids are not supplied during a fire, which could result in an unextinguished fire in the nacelle or APU.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Dassault Model Falcon 2000 airplanes equipped with CFE Company CFE738-1-1B turbofan engines. This proposed AD would require determining the serial number of the engines installed on the airplane, inspecting any affected engine to verify that a spherical bearing is installed on the attachment fitting of the engine mount, and corrective action if necessary. This proposed AD results from a report of a missing spherical bearing on the attachment fitting of the front engine mount on an in-service airplane, and subsequent damage and abnormal fatigue of the attachment fitting. We are proposing this AD to prevent reduced structural integrity of the engine mount, which could result in possible separation of an engine from the airplane.

The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on September 15, 2005 (70 FR 54474). The error resulted in an inadvertent reference to a nonexistent paragraph. This AD applies to certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747- 200C, 747-200F, 747-300, 747SR, and 747SP series airplanes. This AD requires repetitive detailed and ultrasonic inspections of the thrust links of the rear engine mounts for any crack or fracture and corrective actions if necessary.

The FAA is correcting a typographical error in an NPRM that was published in the Federal Register on September 14, 2005 (70 FR 54318). The error resulted in an incorrect Docket No. The NPRM applies to certain Sabreliner Model NA-265, NA-265-20, NA-265-30, NA-265-40, NA-265-50, NA-265-60, NA-265-65, NA-265-70, and NA-265-80 series airplanes. The NPRM would require repetitive inspections for discrepancies in the front and rear spars of the wing in the area of the wing center section, and in the lugs on the rear spar and wing trailing edge panel rib, and corrective actions if necessary. The NPRM also would require inspections for fuel leaks of the front and rear spars of the wing, and for discrepancies in the front and rear spars of the wing in the area of the wing center section, and in the lugs on the rear spar and wing trailing edge panel rib; and related investigative and corrective actions, if necessary.

The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on September 14, 2005 (70 FR 54249). The error resulted in an incorrect Docket No. This AD applies to certain Aerospatiale Model ATR42-500 airplanes. This AD requires inspecting for correct installation of the fastener that attaches the ground braids on the elevator, modifying the forward bonded assembly of the elevator control rod, and corrective action if necessary.
