IFR Altitudes; Miscellaneous Amendments
This action corrects errors in certain amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed listed in a final rule published in the Federal Register on August 2, 2005 (70 FR 44278).
Airworthiness Directives; Saab Model SAAB 2000 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Saab Model SAAB 2000 airplanes. This proposed AD would require modifying the manual feather-and-unfeather system for the propellers to make the design of the system more robust. This proposed AD results from reports of in-flight engine shutdown caused by uncommanded operation of the feather pump of the propeller. We are proposing this AD to prevent uncommanded feathering of the propeller, which could result in the shutdown of an engine during flight and consequent reduced controllability of the airplane.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 Airplanes, and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model EMB-135 airplanes, and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This proposed AD would require modification of the upper frame of the firewall for the auxiliary power unit (APU). This proposed AD results from the discovery of a hole in the upper frame of the firewall for the APU. We are proposing this AD to prevent smoke from entering the passenger cabin in the event of a fire in the APU compartment.
Airworthiness Directives; McDonnell Douglas Model DC-9-10, DC-9-20, DC-9-30, DC-9-40, and DC-9-50 Series Airplanes; McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) Airplanes; McDonnell Douglas Model MD-88 Airplanes; McDonnell Douglas Model MD-90-30 Airplanes; and McDonnell Douglas Model 717-200 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas transport category airplanes. This proposed AD would require an inspection to determine the part number of the upper and lower stop pad support fittings of all the lower cargo doors, repetitive inspections of all early configuration stop pad support fittings, and corrective action if necessary. This proposed AD would also provide an optional terminating action for the repetitive inspections. This proposed AD is prompted by a report of cracks found in the area of the upper and lower stop pad support fittings of the cargo door pan on numerous airplanes. We are proposing this AD to prevent cracks in the cargo door pan, which could result in the inability to fully pressurize an airplane and possible rapid decompression of the airplane.
Airworthiness Directives; General Electric Company CF34-1A, -3A, -3A1, -3A2, -3B, and -3B1 Series Turbofan Engines
The FAA proposes to supersede an existing airworthiness directive (AD) that was issued for General Electric Company (GE) CF34- 3A1 and -3B1 series turbofan engines with certain part numbers (P/Ns) and serial numbers (SNs) of stage 5 low pressure turbine (LPT) disks and stage 6 LPT disks. These engines are installed in Bombardier Canadair CL600-2B19 Regional Jet (RJ) airplanes. This proposed AD would add SNs to the affected disk population for RJ airplanes. This proposed AD would also add GE CF34-1 and -3 series turbofan engines with certain P/Ns and SNs of stage 5 LPT disks and stage 6 LPT disks, to the applicability section. These engines are installed in Bombardier Canadair models CL-600-2A12 (CL-601), CL-600-2B16 (CL-601-3A), (CL-601- 3R), and (CL-604) Business Jet (BJ) airplanes. This proposed AD would require initial and repetitive visual and eddy current inspections (ECI) of the affected disk population. This proposed AD would also allow replacement of those disks as optional terminating action to the repetitive inspections. Also, this proposed AD would require eventual replacement of the affected disks as terminating action to the repetitive inspections. This proposed AD results from the discovery of additional suspect stage 5 LPT disks and stage 6 LPT disks. These disks could fail due to low-cycle fatigue cracking that may start at the site of an electrical arc-out on the disk. We are proposing this AD to prevent low-cycle-fatigue (LCF) failure of stage 5 LPT disks and stage 6 LPT disks, which could lead to uncontained engine failure.
Membership in the National Parks Overflights Advisory Group Aviation Rulemaking Committee
The National Park Service (NPS) and the Federal Aviation Administration (FAA), as required by the National Parks Air Tour Management Act of 2000, established the National Parks Overflights Advisory Group (NPOAG) in March 2001. The NPOAG was formed to provide continuing advice and counsel with respect to commercial air tour operations over and near national parks. On October 10, 2003, the Administrator signed Order No. 1110-138 establishing the NPOAG as an aviation rulemaking committee (ARC). This notice informs the public of a vacancy on the NPOAG ARC, for a member representing air Indian tribal interests, and invites interested persons to apply to fill the vacancy.

This proposed AC provides guidance for manufacturers of aircraft, aircraft engine, and avionics incorporating databuses and databus technology in the design of their aircraft, aircraft engine, or avionics systems. In the proposed AC, we recommend how you as the manufacturer, may get design and airworthiness approval for your databus.
Public Notice for Waiver of Aeronautical Land-Use Assurance; Jackson County-Reynolds Field; Jackson, MI
The Federal Aviation Administration (FAA) is considering a proposal to change a portion of the airport from aeronautical use to non-aeronautical use and to authorize the lease of the airport property. The proposal consists of two (2) parcels of land totaling approximately 68 acres. Current use and present condition is vacant grassland with intermittent wetland areas. The land is currently zoned residential. Parcel 15A was acquired under FAA Project No. 8-26-0051-02. Parcel 62 was not acquired with federal funds. There are no impacts to the airport by allowing the airport to lease the property.The airport desires to enter into a long- term lease to provide a long-term revenue source. Approval does not constitute a commitment by the FAA to financially assist in the disposal of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the lease of the airport property will be in accordance FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. In accordance with section 47107(h) of title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose.
Noise Compatibility Program Revision Notice; Austin, TX
The Federal Aviation Administration (FAA) announces its findings on the Noise Compatibility Program revision submitted by the city of Austin under the provisions of 49 U.S.C. (the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR part 150. These findings are made in recognition of the description of Federal and nonfederal responsibilities in Senate Report No. 96-52 (1980). On April 5 and May 8, 2000, The FAA determined that the noise exposure maps submitted by the city of Austin under part 150 complied with applicable requirements. On August 5, 2005, the FAA approved a revision to the Austin-Bergstrom International Airport Noise Compatibility Program. The program measure in this revision was fully approved.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all Bombardier Model CL-600-2B19 series airplanes. That AD currently requires revising the airplane flight manual (AFM) to provide the flightcrew with operating limitations and procedures to enable them to maintain controllability of the airplane in the event that aileron control stiffness is encountered during flight. This new AD requires revising the Airworthiness Limitations section of the Instructions of Continued Airworthiness to incorporate certain repetitive tasks for the aileron control system and requires a briefing to advise flightcrews that certain aileron control checks are no longer required. After accomplishing the applicable initial tasks, the existing AFM revisions for the aileron control check may be removed from the AFM. This AD results from the development of terminating actions for the AFM revisions. We are issuing this AD to prevent aileron control stiffness during flight, which could result in reduced or possible loss of controllability of the airplane.
Airworthiness Directives; Bombardier Model CL-215-1A10 (Water Bomber), CL-215-6B11 (CL215T Variant), and CL-215-6B11 (CL415 Variant) Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Bombardier Model CL-215-1A10 and CL-215- 6B11 series airplanes. That AD currently requires repetitive ultrasonic inspections to detect cracking of the lower caps of the wing front spar and rear spar, and corrective action if necessary. This new AD reduces the threshold to do the initial inspections and revises the repetitive inspection interval. This new AD also adds a repetitive ultrasonic inspection of the wing lower skin. This AD results from reports of cracks in the front and rear spar lower caps. We are issuing this AD to detect and correct cracking of the lower caps of the wing front spar and rear spar, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Pratt & Whitney JT8D-209, -217, -217A, -217C, and -219 Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Pratt & Whitney (PW) JT8D-209, -217, -217A, -217C, and -219 turbofan engines. That AD currently requires revisions to the engine manufacturer's time limits section (TLS) to include enhanced inspection of selected critical life-limited parts at each piece-part opportunity. This AD requires modifying the airworthiness limitations section of the manufacturer's manual and an air carrier's approved continuous airworthiness maintenance program to incorporate additional inspection requirements. An FAA study of in-service events involving uncontained failures of critical rotating engine parts has indicated the need for mandatory inspections. The mandatory inspections are needed to identify those critical rotating parts with conditions, which if allowed to continue in service, could result in uncontained failures. We are issuing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.
Airworthiness Directives; Pratt & Whitney PW2000 Series Turbofan Engines

This AD requires modifying the airworthiness limitations section of the manufacturer's manual and an air carrier's approved continuous airworthiness maintenance program to incorporate additional inspection requirements. This AD results from an FAA study of in-service events involving uncontained failures of critical rotating engine parts that indicates the need for mandatory inspections. The mandatory inspections are needed to identify those critical rotating parts with conditions, which if allowed to continue in service, could result in uncontained failures. We are issuing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.
Airworthiness Directives; Cirrus Design Corporation Models SR20 and SR22 Airplanes
The FAA adopts a new airworthiness directive (AD) for certain Cirrus Design Corporation (CDC) Models SR20 and SR22 airplanes. This AD requires you to measure and adjust the crew seat break-over bolts and to replace the crew seat recline locks on both crew seats. This AD results from CDC discovering that the crew seats, under emergency landing dynamic loads, may fold forward at less than the 26 g required by the regulations. We are issuing this AD to prevent the crew seats from folding forward during emergency landing dynamic loads with consequent occupant injury.
