Federal Aviation Administration 2006 – Federal Register Recent Federal Regulation Documents

This notice proposes to establish Class E airspace at Butler, GA. Area Navigation (RNAV) Global Positioning System (GPS) and Nondirectional Radio Beacon (NDB) Standard Instrument Approach Procedures (SIAPs) Runway (RWY) 18 and RWY 36 have been developed for Butler Municipal Airport. As a result, controlled airspace extending upward From 700 Feet Above Ground Level (AGL) is needed to contain the SIAPs and for Instrument Flight Rules (IFR) operations at Butler Municipal Airport. The operating status of the airport will change from Visual Flight Rules (VFR) to include IFR operations concurrent with the publication of the SIAPs.

This action proposes special conditions for McCauley Propeller Systems. This 3D15C1401/C80MWX-X model propeller will have a novel or unusual design features(s) associated with composite blades. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the added safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 747-400 series airplanes. The existing AD currently requires replacement of the decompression panels that are located in the smoke barrier between the passenger and main deck cargo compartment with new panels of an improved design. This proposed AD would require modification of the decompression panels on the smoke barrier in the main deck cargo compartment or replacement of the smoke barrier with an improved smoke barrier, as applicable. This proposed AD would also require repetitive inspections of the decompression (vent) panels on the smoke barrier and corrective actions if necessary. This proposed AD also adds airplanes to the applicability. This proposed AD results from reports of decompression panels on the smoke barrier opening in flight and on the ground without a decompression event. We are proposing this AD to prevent inadvertent opening or tearing of decompression panels, which could result in degraded cargo fire detection and suppression capability, smoke penetration into an occupied compartment, and an uncontrolled cargo fire, if a fire occurs in the main deck cargo compartment.

This action establishes Class E airspace at Willow, AK to provide adequate controlled airspace to contain aircraft executing new Instrument Procedures. This rule results in new Class E airspace established upward from 700 feet (ft.) and 1,200 ft. above the surface at Willow, AK.

This action establishes Class D and E4 airspace and amends Class E5 airspace at Leesburg, FL. A Federal contract tower with a weather reporting system is being constructed at the Leesburg Regional Airport. Therefore, the airport will meet the criteria for establishment of Class D and E4 airspace. Class D surface area airspace and Class E4 airspace desiganted as an extension to Class D airspace is required when the control tower is open to contain existing Standard Instrument Approach Procedures (SIAPs) and other Instrument Flight Rules (IFR) operations at the airport. This action will establish Class D airspace extending upward from the surface to but not including 1,600 feet MSL, within a 4.1-mile radius of the Leesburg Regional Airport and a Class E4 airspace extension that is 4.8 miles wide and extends 7 miles southeast of the airport. This action will also amend Class E5 airspace extending upward from 700 feet Above Ground Level (AGL) needed to contain SIAPs, by decreasing the size from a 7-mile radius of the airport to a 6.6-mile radius of the airport and providing for the procedure turn area. Additionally, a technical amendment will result in a name change from the Leesburg Municipal Airport to the Leesburg Regional Airport, which was effective August 25, 1997.

This action establishes Class E airspace at Mooresville, NC. An Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) Runway (RWY) 14 has been developed for Lake Norman Airpark. As a result, controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to contain the SIAP and for Instrument Flight Rules (IFR) operations at Lake Norman Airpark. The operating status of the airport will change from Visual Flight Rules (VFR) to include IFR operations concurrent with the publication of the SIAP.

The FAA is superseding an existing airworthiness directive (AD) for Hamilton Sundstrand model 14RF-19 propellers. That AD currently requires replacing certain actuator yokes with improved actuator yokes. This AD requires the same actions. This AD results from the discovery of a part number (P/N) error in the applicability paragraph of AD 2006-12-19. We are issuing this AD to prevent actuator yoke arms breaking during flight, which could cause high propeller vibration and contribute to reduced controllability of the airplane.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-300, -400, -500, -600, -700, -700C, -800, and -900 series airplanes. This AD requires modifying the wiring for the master dim and test system. For certain airplanes, this AD also requires related concurrent actions as necessary. This AD results from a report that the master dim and test system circuit does not have wiring separation of the test ground signal for redundant equipment in the flight compartment. We are issuing this AD to prevent a single fault failure in flight from simulating a test condition and showing test patterns instead of the selected radio frequencies on the communications panels, which could inhibit communication between the flightcrew and the control tower, affecting the continued safe flight of the airplane.

The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires modification of the wiring distribution of the alternating current bus transfer power system and the right-hand and left-hand windshield anti- icing system, as necessary. This AD results from a report of electrical sparks coming out of the flight deck from a panel behind the left seat. We are issuing this AD to prevent failure of the sliding window heating element(s), due to electrical overload, which could result in smoke and fire in the cockpit.

We propose to supersede Airworthiness Directive (AD) 62-24-01, which applies to all Raytheon Aircraft Company (Raytheon) Beech Models 45 (YT-34), A45 (T-34A, B45), and D45 (T-34B) airplanes. AD 62-24-01 currently requires you to repetitively inspect, using the dye penetrant method, the front and rear horizontal stabilizer spars for cracks and replace any cracked stabilizer. Since we issued AD 62-24-01, we determined that using dye penetrant inspection method may not detect cracks before failure of the horizontal stabilizer spars. Therefore, we are proposing to require the surface eddy current inspection method to detect cracks in the horizontal stabilizer spars. Consequently, this proposed AD would retain the actions required in AD 62-24-01 and change the required inspection method from dye penetrant to surface eddy current. We are proposing this AD to prevent failure of the front and rear horizontal stabilizer spars caused by fatigue cracks. This failure could result in stabilizer separation and loss of control of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model ERJ 170 airplanes. This proposed AD would require replacing the mini-latches on certain lavatory waste compartment doors with new, stronger latches, and other specified actions. This proposed AD results from reports of certain lavatory waste compartment doors opening during flight due to movement of the waste compartment during takeoff, because the mini-latches installed on the doors of those compartments lose their strength over time. We are proposing this AD to prevent the inability of the waste compartment doors to adequately contain a fire inside the lavatory waste compartment, and consequent uncontained fire and smoke within a lavatory during flight.

This amendment adopts miscellaneous 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. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.

These special conditions are issued for the Piper PA 28-161 Cadet, Warrior II and Warrior III series airplanes, with the installation of a Thielert Aircraft Engines (TAE) Model TAE 125-1 aircraft diesel engine (ADE). These airplanes will have a novel or unusual design feature(s) associated with the installation of a diesel cycle engine utilizing turbine (jet) fuel. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for installation of this new technology engine. 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.

This amendment revises an existing airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS-365N2, AS 365 N3, EC 155B, EC155B1, SA-365N, N1, and SA-366G1 helicopters that currently requires inspecting the main gearbox (MGB) base plate for a crack and replacing the MGB if a crack is found. This amendment increases the time intervals for inspecting the MGB base plate and includes minor editorial changes throughout the AD. This amendment is prompted by crack growth tests that indicate that the inspection intervals can be increased without affecting safety. The actions specified by this AD are intended to detect a crack in an MGB base plate and prevent failure of one of the MGB attachment points to the frame, which could result in severe vibration and subsequent loss of control of the helicopter.

The FAA proposes to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. This proposed AD would require modifying the nose landing gear. This proposed AD results from reports of loss of the nose wheel assembly. We are proposing this AD to prevent the nose wheel nut from loosening, and consequently, the nose wheel assembly detaching from the airplane; and to prevent the nose wheel clamping loads from applying to the machined radius at the root of the stub axle, which could result in damage to the nose landing gear.

The FAA is proposing new and revised airworthiness standards for normal and transport category rotorcraft due to technological advances in design and operational trends in normal and transport rotorcraft performance and handling qualities. The changes would enhance the safety standards for performance and handling qualities to reflect the evolution of rotorcraft capabilities.

The FAA is adopting a new airworthiness directive (AD) for certain CASA Model C-212-CC airplanes. This AD restricts the operation of the airplane to carrying either passengers or cargo (but not both) in the same compartment, unless the airplane is modified to include an approved protective liner between the passengers and the cargo. This AD results from our determination that affected airplanes, when carrying both cargo and passengers in the same compartment, cannot achieve the required level of performance. We are issuing this AD to prevent a hazardous quantity of smoke, flames, and/or fire extinguishing agent from the cargo compartment from entering a compartment occupied by passengers or crew.

The FAA is adopting a new airworthiness directive (AD) for all 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); and Model A310-200 and -300 series airplanes. This AD requires a one-time inspection of the trimmable horizontal stabilizer actuator (THSA), corrective actions if necessary, and follow-on repetitive tasks. This AD results from reports of THSAs that have reached their design operational life. We are issuing this AD to extend the operational life of the THSA to prevent a possible failure of high- time THSAs, which could result in reduced controllability of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A310 airplanes. This proposed AD would require revising the Limitations section of the airplane flight manual by incorporating restrictions for high altitude operations. This proposed AD results from several incidents of pitch oscillations with high vertical loads that occurred during turbulence at high altitudes. We are proposing this AD to prevent pitch oscillations during turbulence, which could result in reduced controllability of the airplane.

This action revises the Class E airspace at Kalispell, MT. Additional controlled airspace is necessary for the safety of Instrument Flight Rules (IFR) aircraft executing the published Instrument Landing System (ILS) approach procedures to the newly extended runway at Kalispell/Glacier Park International Airport, Kalispell, MT.

This action amends the Norton Sound Low Offshore Airspace Area in Alaska. Specifically, this action modifies the Norton Sound Low Offshore Airspace Area in the vicinity of the Shishmaref Airport, AK, by lowering the offshore airspace floor to 1,200 feet mean sea level (MSL) within a 30-mile radius of the airport. Additionally, this action modifies the airspace in the vicinity of Nome Airport, AK, by lowering the airspace floor to 700 feet MSL within a 25-mile radius of the airport, and 1,200 feet MSL within a 77.4-mile radius of the Nome VORTAC. The FAA is taking this action to provide additional controlled airspace for aircraft instrument flight rules (IFR) operations at the Nome and Shishmaref Airports.

The FAA is issuing this notice to advise the public that an EIS will be prepared for the proposed approval of Operation Specifications for Horizon Air to provide commercial airline service with regional jets into Mammoth Yosemite Airport, Mammoth Lakes, California utilizing Bombardier DHC-8-402 (Q400). The establishment of scheduled commercial service into Mammoth Yosemite Airport also necessitates a change in the airport's 14 CFR Part 139 Certification from Class IV to Class I. If the FAA determines the potential environmental impacts of the proposed actions are not significant, FAA may consider, after public notification and agency coordination, completing the NEPA process for this proposal as an Environmental Assessment and issuing a Finding of No Significant Impact and Record of Decision. To ensure that all significant issues related to the proposed action are identified, one (1) public scoping meeting and one (1) governmental and public agency scoping meeting will be held.

This amendment amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

These amended special conditions are issued to Avidyne Corporation, 55 Old Bedford Road, Lincoln, MA 01773. This is an amendment to special condition 23-184-SC, which was published on May 23, 2006 (71 FR 29574), for installation of an EFIS manufactured by Avidyne on various models. The original issue left off the Cirrus Design Corporation SR22, which was the first model to be certified under the STC.
