Airworthiness Directives; Boeing Model 737-600, -700, -700C, and -800 Series Airplanes
Document Number: E6-9174
Type: Proposed Rule
Date: 2006-06-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to revise an existing airworthiness directive (AD) that applies to certain Boeing Model 737-600, -700, -700C, and - 800 series airplanes. The existing AD currently requires inspecting/ measuring the length of the attachment fasteners between the nacelle support fittings and the lower wing skin panels, and related investigative/corrective actions if necessary. This proposed AD would correct errors found in the existing AD. This proposed AD results from detection of those inadvertent errors. We are proposing this AD to prevent inadequate fastener clamp-up, which could result in cracking of the fastener holes, cracking along the lower wing skin panels, fuel leaking from the wing fuel tanks onto the engines, and possible fire.
Airworthiness Directives; Boeing Model 737-600, -700, -700C, -800 and -900 Series Airplanes
Document Number: E6-9163
Type: Proposed Rule
Date: 2006-06-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800 and -900 series airplanes. This proposed AD would require replacing the aero/fire seals of the blocker doors on the thrust reverser torque boxes on the engines with new, improved aero/fire seals. This proposed AD results from a report that the top three inches of the aero/fire seals of the blocker doors on the thrust reverser torque boxes are not fireproof. We are proposing this AD to prevent a fire in the fan compartment (a fire zone) from migrating through the seal to a flammable fluid in the thrust reverser actuator compartment (a flammable leakage zone), which could result in an uncontrolled fire.

Date: 2006-06-13
Agency: Federal Aviation Administration, Department of Transportation
The Federal Aviation Administration (FAA) is giving notice that a portion of the airport property containing 16.6 acres located across the Waupaca River from the airport and is not needed for aeronautical use as currently identified on the Airport Layout Plan. This parcel was originally purchased as part of a larger City purchase in December 1944. The parcel is presently open and undeveloped. The land comprising this parcel is, therefore, no longer needed for aeronautical purposes. Income from the sale will be used to improve the airport. There are no impacts to the airport by allowing the airport to dispose of the property. 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.
Public Notice for Waiver of Aeronautical Land-Use Assurance Boscobel Municipal Airport, Boscobel, WI
Document Number: 06-5324
Type: Notice
Date: 2006-06-13
Agency: Federal Aviation Administration, Department of Transportation
The Federal Aviation Administration (FAA) is giving notice that a portion of the airport property containing 60.6 acres located between the airport and the Wisconsin River is not needed for aeronautical use as currently identified on the Airport Layout Plan. This parcel was originally acquired through Grant No. AIP-01 in 1998. The parcel was an uneconomic remnant left from land acquisition from an airport expansion project, presently open and undeveloped. The land comprising this parcel is, therefore, no longer needed for aeronautical purposes. The sale of this parcel will allow for the airport to purchase other property that will provide approach protection for the airport. Income from the sale will be used to improve the airport. There are no impacts to the airport by allowing the airport to dispose of the property. 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.
Safe, Efficient Use and Preservation of the Navigable Airspace
Document Number: 06-5319
Type: Proposed Rule
Date: 2006-06-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to amend the regulations governing objects that may affect the navigable airspace. Specifically, the FAA is proposing to add notification requirements and obstruction standards for electromagnetic interference and amend the obstruction standards for civil airport imaginary surfaces to more closely align these standards with FAA airport design and instrument approach procedure criteria. The FAA proposes to require proponents to file with the agency a notice of proposed construction or alteration of structures near private use airports that have an FAA approved instrument approach procedure. This proposal, if adopted, would also increase the number of days in which a notice must be filed with the FAA before beginning construction or alteration; add and amend definitions for terms commonly used during the aeronautical evaluation process; and remove the provisions for public hearings and antenna farms. Lastly, the FAA proposes to retitle the rule and reformat it into sections that closely reflect the aeronautical study process. These proposals incorporate case law and legislative action, and simplify the rule language. The intended effect of these proposed changes is to improve safety and promote the efficient use of the National Airspace System.
Airworthiness Directives; Boeing Model 737-200C Series Airplanes
Document Number: 06-5287
Type: Rule
Date: 2006-06-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD) which applies to all Boeing Model 737-200C series airplanes. That AD currently requires a one-time external detailed inspection for cracking of the fuselage skin in the lower lobe cargo compartment; repetitive internal detailed inspections for cracking of the frames in the lower lobe cargo compartment; repair of cracked parts; and terminating action for the repetitive internal detailed inspections. This new AD restates the requirements of the existing AD and adds a requirement to perform repetitive detailed inspections of the body station (BS) 360 and BS 500 fuselage frames, after accomplishing the terminating action, and repair if necessary. This AD results from multiple reports that the existing AD is not fully effective in preventing cracks in the BS 360 and BS 500 fuselage frames. We are issuing this AD to detect and correct cracking of the fuselage frames from BS 360 to BS 500B, which could lead to loss of the cargo door during flight and consequent rapid decompression of the airplane.
Airworthiness Directives; Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, -314, and -315 Airplanes; Equipped With Certain Cockpit Door Installations
Document Number: 06-5286
Type: Rule
Date: 2006-06-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, -314, and -315 airplanes. This AD requires certain Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, -314, and -315 airplanes. This AD results from a report that, during structural testing of the cockpit door, the lower hinge block rotated and caused the mating hinge pin to disengage, and caused excessive door deflection. We are issuing this AD to prevent failure of a door attachment, which could result in uncontrolled release of the cockpit door under certain fuselage decompression conditions, and possible damage to the airplane structure.
Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
Document Number: 06-5285
Type: Rule
Date: 2006-06-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This AD requires repetitive inspections for cracks of the first fuel access panel outboard of the nacelle on the left- and right-hand wings, and related investigative/corrective actions if necessary. This AD also requires eventual replacement of each access panel with a new access panel having a new part number. The replacement terminates the repetitive inspection requirements. This AD results from reports of cracks of the fuel access panels. We are issuing this AD to detect and correct cracked fuel access panels, which could lead to arcing and ignition of fuel vapor during a lightning strike, and result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Hamilton Sundstrand Model 14RF-19 Propellers
Document Number: 06-5284
Type: Rule
Date: 2006-06-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for Hamilton Sundstrand model 14RF-19 propellers. This AD requires replacing certain actuator yokes with improved actuator yokes. This AD results from certain propeller system actuator yoke arms breaking during flight. 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.
Airworthiness Directives; Empresa Brasileira del Aeronautica S.A. (EMBRAER) Model EMB-120, -120ER, -120FC, -120QC, and -120RT Airplanes
Document Number: 06-5245
Type: Rule
Date: 2006-06-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-120, -120ER, -120FC, -120QC, and -120RT airplanes. This AD requires replacing the shut-off and crossbleed valves of the bleed air system with new valves having hermetically sealed switches. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent a potential source of ignition near a fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Airbus Model A300 B2 and A300 B4 Series Airplanes; A300 B4-600, B4-600R, and F4-600R Series Airplanes; and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
Document Number: 06-5244
Type: Rule
Date: 2006-06-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A300 and A300-600 series airplanes. That AD currently requires repetitive inspections to detect cracks in Gear Rib 5 of the main landing gear (MLG) attachment fittings at the lower flange, and repair, if necessary. That AD also requires modification of Gear Rib 5 of the MLG attachment fittings, which constitutes terminating action for the repetitive inspections. This new AD requires new repetitive inspections at reduced compliance times. This new AD also requires new repetitive inspections of certain areas of the attachment fittings that were repaired in accordance with the actions specified in the existing AD. This AD results from new service information that was issued by the manufacturer and mandated by the French airworthiness authority. We are issuing this AD to prevent fatigue cracking of the MLG attachment fittings, which could result in reduced structural integrity of the airplane.
