Federal Aviation Administration September 6, 2012 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2012-21946
Type: Proposed Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-100-1A10 (Challenger 300) airplanes. This proposed AD was prompted by reports of failure of a screw cap or end cap of the auxiliary hydraulic system accumulator while on the ground, which resulted in loss of use of that hydraulic system and high-energy impact damage to adjacent systems and structures. This proposed AD would require inspecting for the correct serial number of a certain hydraulic system accumulator, and replacing affected hydraulic system accumulators with new or serviceable accumulators. We are proposing this AD to prevent failure of a screw cap or end cap and loss of the related hydraulic system, which could result in damage to airplane structure and consequent reduced controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-21944
Type: Proposed Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 727, 727C, 727-100, 727-100C, 727-200, and 727-200F series airplanes. This proposed AD was prompted by a structural re-evaluation by the manufacturer, which identified elements within the wing trailing edge flap area that qualify as structural significant items (SSI). This proposed AD would require revising the maintenance inspection program to include inspections that will give no less than the required damage tolerance rating for certain SSIs, and repairing cracked structure. We are proposing this AD to detect and correct fatigue cracking of the wing trailing edge structure, which could result in compromised structural integrity of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-21933
Type: Proposed Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 747-400 and 747- 400F series airplanes. The existing AD currently requires installing drains and drain tubes to eliminate water accumulation in the dripshield above the M826 cardfile in the main equipment center. Since we issued that AD, we received reports of continued water damage to diode fire card 285U0072-1 in the M826 automatic fire overheat logic test system cardfile following a false FWD CARGO FIRE message, with no change in frequency, which resulted in an air turn back. This proposed AD would instead require installing drain tubes, relocating wire bundle routing, installing a new drip shield and drip shield deflectors, and replacing insulation blankets. For certain airplanes, this proposed AD would also concurrently require sealing the drain slot, installing spuds, and installing drain tubes. We are proposing this AD to prevent water from exiting over the edge of the existing drip shield and contaminating electrical components in the M826 cardfile, which could result in an electrical short and potential loss of several functions essential for safe flight.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-21931
Type: Proposed Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 767 airplanes. The existing AD currently requires sealing certain fasteners and stiffeners in the fuel tank, changing certain wire bundle clamp configurations on the fuel tank walls, inspecting certain fasteners in the fuel tanks and determining the method of attachment of the vortex generators, and performing corrective action if necessary. We issued that AD to prevent possible ignition sources in the auxiliary (center) fuel tank, main fuel tanks, and surge tanks caused by a wiring short or lightning strike, which could result in fuel tank explosions and consequent loss of the airplane. Since we issued that AD, another possible ignition source location was identified. This proposed AD would add a general visual inspection for the presence of a polytetrafluoroethylene (TFE) sleeve at the clamp location on the rear spar, and installation of a TFE sleeve if necessary. This proposed AD would also add airplanes to the applicability. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-21928
Type: Proposed Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-300, -400, -500, -600, -700, - 700C, -800, -900, and -900ER series airplanes. This proposed AD was prompted by a review of the tail strobe light installation, which revealed that the tail strobe light is not electrically bonded to primary structure of the airplane. This proposed AD would require installing a new tail strobe light housing and a new disconnect bracket, and changing the wire bundles. We are proposing this AD, in case of a direct lightning strike to the tail strobe light, to prevent damage to the operation of other critical airplane systems due to electromagnetic coupling and large transient voltages, and damage to the control mechanisms or surfaces due to a fire, which could result in loss of control of the airplane.
Revocation of Jet Route J-528; WA
Document Number: 2012-21842
Type: Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
This action removes Jet Route J-528 because the route is too short to serve a useful navigation or air traffic control purpose and is causing flight plan rejections in the air traffic control automation system.
Airworthiness Directives; the Boeing Company Airplanes
Document Number: 2012-21838
Type: Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model DC-9-10, DC-9-20, DC-9-30, DC-9-40, and DC-9- 50 series airplanes; and Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9- 83 (MD-83), DC-9-87 (MD-87), MD-88, and MD-90-30 airplanes; equipped with center wing fuel tank and Boeing original equipment manufacturer- installed auxiliary fuel tanks. This AD was prompted by fuel system reviews conducted by the manufacturer. This AD requires adding design features to detect electrical faults and to detect a pump running in an empty fuel tank. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Amendment of Class D and Class E Airspace; Lakehurst, NJ; Correction
Document Number: 2012-21830
Type: Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
This action corrects the geographic coordinates in the airspace description of a final rule, published in the Federal Register on July 10, 2012, amending controlled airspace at Lakehurst Naval Support Activity/Maxfield Field (Joint Base McGuire-Dix-Lakehurst).

Document Number: 2012-21827
Type: Proposed Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to modify VHF Omnidirectional Range (VOR) Federal airway V-170 between Devils Lake, ND (DVL), and Jamestown, ND (JMS). The FAA is proposing this action to ensure the airway provides the necessary clearance from the western boundary of the newly established restricted area R-5402, Devils Lake, ND, to support non- radar separation requirements when the restricted area is active.
Proposed Establishment of VOR Federal Airway V-629; Las Vegas, NV
Document Number: 2012-21824
Type: Proposed Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to establish a new VHF Omnidirectional Range (VOR) Federal airway near Las Vegas, NV, to supplement the existing route structure for aircraft navigating in an area of marginal radar coverage. This would enhance the efficiency of the National Airspace System (NAS).
Airworthiness Directives; Pratt & Whitney Division Turbofan Engines
Document Number: 2012-21821
Type: Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Pratt & Whitney Division PW4000-94'' and PW4000-100'' turbofan engines having a 1st stage high-pressure turbine (HPT) seal support, part number (P/N) 55K601 (contained within assembly P/N 55K602-01) or P/N 50K532 (contained within assembly P/N 50K530-01), installed. This AD was prompted by 58 reports of cracked 1st stage HPT air seal rings, including 15 in-flight engine shutdowns. This AD requires removal and replacement of the 1st stage HPT seal support and inspection of the 1st stage HPT air seal ring. We are issuing this AD to prevent failure of the 1st stage HPT air seal ring, which could lead to an internal oil fire, uncontained engine failure, and damage to the airplane.
Airworthiness Directives; Diamond Aircraft Industries GmbH Airplanes
Document Number: 2012-21653
Type: Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Diamond Aircraft Industries GmbH Models DA 42, DA 42 NG, and DA 42 M-NG airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as excessive voids in the adhesive joint between the center wing spars and the upper center wing skins. This condition could cause the wing to fail, which could result in loss of control of the airplane. We are issuing this AD to require actions to address the unsafe condition on these products.

Type: Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 series airplanes. This AD was prompted by reports of water leaking into electrical and electronic equipment in the main equipment center (MEC). This AD requires modifying the floor panels; removing drains; installing floor supports, floor drain trough doublers, drain troughs, and drains; and sealing and taping the floor panels. We are issuing this AD to prevent water from entering the MEC, which could result in an electrical short and potential loss of several functions essential for safe flight.
Airworthiness Directives; BAE SYSTEMS (Operations) Limited Airplanes
Document Number: 2012-21288
Type: Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. This AD was prompted by reports that the fire extinguisher in the toilet vanity unit needs to be mounted vertically rather than horizontally. This AD requires inspecting to determine if a certain fire extinguisher bottle is installed, and repositioning the affected fire extinguisher bottle to the vertical position. We are issuing this AD to detect and correct the orientation of the fire extinguisher bottle in the toilet vanity unit to the vertical position, which if not corrected, could result in a toilet waste bin fire spreading, and consequent damage to the airplane and injury to its occupants.
Airworthiness Directives; Eurocopter France Helicopters
Document Number: 2012-21261
Type: Rule
Date: 2012-09-06
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Eurocopter France Model AS350 helicopters. This AD requires installing protection sleeves over certain forward (pitch) servo-control hydraulic hoses. This AD was prompted by an in-flight fire caused by the ignition of hydraulic fluid leaking from a damaged forward servo-control hydraulic hose. This AD's actions are intended to prevent the forward servo-control hydraulic hoses from becoming damaged and leaking hydraulic fluid that could ignite in flight, which could result in loss of main rotor (M/R) control, power loss, structural damage, propagation of fire, and subsequent loss of control of the helicopter.
