This document corrects an error that appeared in Docket No. NM438, Special Conditions No. 25-423-SC, which were published in the Federal Register on March 28, 2011. The error resulted in the omission of two paragraphs of text in The Special Conditions section.
Airworthiness Directives; Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Galaxy and Gulfstream 200 airplanes. This proposed AD was prompted by reports of degraded brake performance during landing due to improperly-sized wear indicating pins. This proposed AD would require determining the lengths of the wear indicating pins of all brake assemblies, shortening the pin if the wear indicating pin is too long, inspecting for normal brake wear, and replacing brakes with new brakes if necessary. We are proposing this AD to detect and correct improperly-sized wear indicating pins, which, if not corrected, could result in worn-out brake pads and subsequent loss of braking power, which could result in runway overruns.
Airworthiness Directives; Airbus Airplanes
We propose to supersede an existing airworthiness directive (AD) for all Airbus Model A318-111 and -112 airplanes; and all Model A319, A320, and A321 series airplanes. The existing AD currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. Since we issued that AD, Airbus has issued more restrictive maintenance requirements and/or airworthiness limitations. This proposed AD would revise the maintenance program to incorporate revised fuel maintenance and inspection tasks, and add airplanes to the applicability. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; The Boeing Company Model 747 Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 747 airplanes. The existing AD currently requires repetitive visual inspections around the bushings of the wing landing gear (WLG) beam outboard end fittings for corrosion, and rework if necessary; and ultrasonic inspections for cracks of the outboard end fittings of the WLG support beams, and rework if necessary. Since we issued that AD, there have been new reports of corrosion damage to the end fittings of the WLG support beams, and one report of subsequent cracking in the end fittings. This proposed AD would add airplanes and repetitive inspections of the outboard end fitting of the left and right WLG support beams for cracks and corrosion, and corrective actions if necessary. We are proposing this AD to detect and correct corrosion and subsequent cracking in the outboard end fittings, which could result in separation of the fitting and damage to adjacent flight control cables and hydraulic systems and consequent reduced controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. The existing AD currently requires inspecting for scribe lines in the skin along lap joints, butt joints, certain external doublers, and the large cargo door hinges, and related investigative and corrective actions if necessary. Since we issued that AD, we have determined that scribe lines could occur where external decals are installed or removed across lap joints, large cargo door hinges, or external doublers. This proposed AD would add inspecting for scribe lines where external decals have been applied or removed across lap joints, large cargo door hinges, and external doublers, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct scribe lines which can develop into fatigue cracks in the skin. Undetected fatigue cracks can grow and cause sudden decompression of the airplane.
Airworthiness Directives; Honeywell International, Inc. Turbofan Engines
We are adopting a new airworthiness directive (AD) for all Honeywell International, Inc. ALF502L-2C; ALF502R-3; ALF502R-3A; ALF502R-5; LF507-1F; and LF507-1H turbofan engines. This AD was prompted by two reports of engines experiencing uncontained release of low-pressure (LP) turbine blades. This AD requires operational checks of the engine overspeed trip system. We are issuing this AD to prevent LP turbine overspeed leading to uncontained release of the LP turbine blades and damage to the airplane.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We are adopting a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-Trent 800 series turbofan engines. This AD requires removal from service of certain critical engine parts based on reduced life limits. This AD was prompted by RR adding a new flight profile and an associated set of life limits. We are issuing this AD to prevent the failure of critical rotating parts, which could result in uncontained failure of the engine and damage to the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 707 airplanes, and Model 720 and 720B series airplanes. This proposed AD was prompted by reports of cracking of the midspar fittings, and of the engine and nacelle strut separating from the airplane. This proposed AD would require performing a detailed inspection of the midspar fittings of the nacelle strut to confirm that the correct part number is installed, and installing the correct part number if necessary; performing repetitive high frequency eddy current inspections (HFEC) of the midspar fittings of the nacelle strut for cracks, and repair if necessary; and performing repetitive general visual inspections of the nacelle struts to verify that the nacelle strut has not drooped below its normal position, applying the droop stripe to the nacelle strut and sailboat fairing if necessary, and repair if necessary. We are proposing this AD to detect and correct cracking of the midspar fitting, which could result in separation of the nacelle strut and engine from the airplane while in flight, and consequent loss of controllability of the airplane.
Airworthiness Directives; the Boeing Company Airplanes
We are revising an earlier proposed airworthiness directive (AD) for certain the Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes. That NPRM proposed to inspect for part numbers of the operational program software of the flight control computers, and corrective actions if necessary. That NPRM was prompted by reports of undetected erroneous output from a single radio altimeter channel, which resulted in premature autothrottle retard during approach. This action revises that NPRM by also proposing to supersede an existing AD. We are proposing this supplemental NPRM to detect and correct an unsafe condition associated with erroneous output from a radio altimeter channel, which could result in premature autothrottle landing flare retard and the loss of automatic speed control, and consequent loss of control of the airplane. Since the proposal to now supersede an existing AD may impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on this proposed change.
Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes
We are adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model G-1159, G-1159A, and G-1159B airplanes. This AD requires, for certain airplanes, a measurement to determine the clearance (gap) of the exposed rounded portion of the doubler and clothespin fitting at the wing-to-fuselage attachment, and repair if necessary. This AD also requires, for certain other airplanes, determining if a certain aircraft service change has been incorporated, and for affected airplanes, a measurement to determine the clearance (gap) of the exposed rounded portion of the doubler and clothespin fitting at the wing-to-fuselage attachment, and repair if necessary. This AD was prompted by a report of an improper structural modification that had excessive gaps in the wing-to-fuselage attachment fittings. We are issuing this AD to detect and correct excessive gaps in the wing-to-fuselage attachment fittings, which could result in reduced structural integrity at the wing-to-fuselage attachment and consequent separation of the wing from the airplane.
Withdrawal of Notice of Intent To Prepare an Environmental Impact Statement for the George Bush Intercontinental Airport, Houston, TX
The FAA is issuing this notice to advise federal, state, and local government agencies and the public that the FAA is withdrawing its Notice of Intent to prepare an Environmental Impact Statement (EIS) for proposed capacity improvements at the George Bush Intercontinental Airport (IAH). The Houston Airport System (HAS), the sponsor of the proposed improvements, has requested that the EIS be terminated because the need for the proposed capacity improvements no longer exists. The HAS noted that arrival and departure delays at IAH have been decreasing and stated that IAH is currently one of the least delayed large hub airports in the United States.
Proposed Establishment of Class E Airspace; Chenega Bay, AK
This action proposes to establish Class E airspace at Chenega Bay Airport, Chenega Bay, AK, to accommodate aircraft using new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Chenega Bay Airport, Chenega Bay, AK. The FAA is proposing this action to enhance the safety and management of aircraft operations at the airport.
Airworthiness Directives; Rolls-Royce plc (RR) Turbofan Engines
We are superseding an existing airworthiness directive (AD) for all RR RB211-Trent 553-61, 553A2-61, 556-61, 556A2-61, 556B-61, 556B2-61, 560-61, 560A2-61, 768-60, 772-60, 772B-60, 875-17, 877-17, 884-17, 884B-17, 892-17, 892B-17, and 895-17 turbofan engines. That AD currently requires inspecting the intermediate-pressure (IP) compressor rotor shaft rear balance land for cracks. This new AD continues to require initial inspections, adds additional inspections, and a mandatory terminating action. This AD was prompted by additional cracking on RB211-Trent 700 and RB211-Trent 800 IP compressor rotor shafts found since the existing AD was issued. We are issuing this AD to detect cracking on the IP compressor rotor rear balance land. IP compressor rotor rear balance land cracking can lead to uncontained failure of the rotor and damage to the airplane.
Meeting: RTCA Program Management Committee
The FAA is issuing this notice to advise the public of a meeting of the RTCA Program Management Committee.
Airworthiness Directives; Bell Helicopter Textron Canada Limited Helicopters
We are adopting a new airworthiness directive (AD) for Bell Helicopter Textron Canada Limited (BHTC) Model 427 helicopters which requires replacing certain tailboom attachment hardware and at certain intervals thereafter, determining the torque of that tailboom attachment hardware. This AD was prompted by a review of the tailboom attachment installation, which revealed that the torque value of the bolts specified in the BHTC Model 427 Maintenance Manual and applied during manufacturing was incorrect and exceeded the torque range recommended for the bolts. The actions are intended to prevent an over- torque of the tailboom attachment bolt (bolt), bolt failure, loss of the tailboom, and subsequent loss of control of the helicopter.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702); CL-600-2D15 (Regional Jet Series 705); CL-600-2D24 (Regional Jet Series 900); and CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by reports of deformation of the pressure regulator on the oxygen cylinder, which was attributed to batches of raw material that did not meet required tensile strength. This AD requires an inspection to determine if certain oxygen pressure regulators are installed, and replacement of oxygen cylinder and regulator assemblies (CRAs) containing pressure regulators that do not meet required material properties. We are issuing this AD to prevent elongation of the pressure regulator neck, which could result in rupture of the oxygen cylinder, and in the case of cabin depressurization, oxygen would not be available when required.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing 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.

Airworthiness Directives; Piper Aircraft, Inc. Airplanes
We are superseding an existing airworthiness directive (AD) for certain Piper Aircraft, Inc. (type certificate previously held by The New Piper Aircraft Inc.) Models PA-31T and PA-31T1 airplanes. That AD currently requires correcting a model identification error on the aircraft data plate. Since we issued that AD, we have become aware that some owner/operators of the affected airplanes modified the aircraft data plate in error because of confusion in the serial number applicability. Because of the confusion, the manufacturer has issued new service information to clarify affected airplane serial numbers. This new AD requires determining the airplane model based on the serial number and modifying the aircraft data plate to properly identify the airplane model. This new AD also requires doing a detailed search for all applicable airworthiness related documents that apply to any airplane that has an incorrectly marked data plate and take necessary corrective actions based on the search findings. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD was prompted by reports of corrosion damage on the outer diameter chrome surface of the horizontal stabilizer pivot pins. Micro-cracks in the chrome plating of the pivot pin, some of which extended into the base metal, were also reported. This condition, if not corrected, could result in a fractured horizontal stabilizer pivot pin. This AD requires replacing the existing horizontal stabilizer pivot pins with new or reworked pivot pins having improved corrosion resistance, doing repetitive inspections after installing the pivot pins, and doing corrective actions if necessary. We are issuing this AD to prevent a fractured horizontal stabilizer pivot pin, which may cause excessive horizontal stabilizer freeplay and structural damage significant enough to result in loss of control of the airplane.

Airworthiness Directives; Continental Motors, Inc. (CMI) Reciprocating Engines
We are superseding an existing airworthiness directive (AD) for certain Continental Motors, Inc. (CMI) models TSIO-520, TSIO-550-K, TSIOF-550K, and IO-550-N series reciprocating engines with new or rebuilt CMI starter adapters installed between January 1, 2011 and November 20, 2011. That AD currently requires replacing affected CMI starter adapters with starter adapters eligible for installation. This AD requires the same actions, but to an expanded population of reciprocating engines. This AD was prompted by two additional reports received of fractures in starter adapter gear shafts in certain additional part number (P/N) CMI starter adapters since we issued the existing AD. We are issuing this AD to prevent starter adapter gear shaft failure which could cause oil scavenge pump failure and engine in-flight shutdown.
Clarification of Prior Interpretations of the Seat Belt and Seating Requirements for General Aviation Flights
This action clarifies prior interpretations of FAA's seat belt and seating requirements. These prior interpretations state that the shared use of a single restraint may be permissible. This clarification states that the use of a seat belt and/or seat by more than one occupant is permitted only if the seat usage conforms to the limitations contained in the approved portion of the Airplane Flight Manual (AFM). In addition, before multiple occupants use the same seat and/or seat belt, if the pertinent information is available, the pilot in command (PIC) must also check whether: The seat belt is approved and rated for such use; and the structural strength requirements for the seat are not exceeded. This clarification also emphasizes that, because it is safer for each individual person to have his or her own seat and seat belt, whenever possible, each person onboard an aircraft should voluntarily be seated in a separate seat and be restrained by a separate seat belt.
Amendment of Restricted Area R-2502E; Fort Irwin, CA
This action changes the designated controlling agency for restricted area R-2502E, Fort Irwin, CA, from the Federal Aviation Administration, High-Desert Terminal Radar Approach Control (TRACON), Edwards, CA, to FAA, Los Angeles Air Route Traffic Control Center (ARTCC). This change will improve the efficiency of air traffic operations in the vicinity of Fort Irwin, CA.
Amendment of Area Navigation (RNAV) Route Q-130; UT
This action amends the description of RNAV route Q-130 by changing the name of the MRRNY waypoint to ROCCY. The FAA is taking this action following a pilot deviation incident wherein confusion resulted from the two similarly sounding waypoint names in the Q-130 description. In addition, the FAA is making minor editorial changes to the route description to standardize the format.
Airworthiness Directives; Pratt & Whitney Division Turbofan Engines
We propose to supersede an existing airworthiness directive (AD) that applies to all Pratt & Whitney Division (Pratt & Whitney) PW4052, PW4056, PW4060, PW4062, PW4062A, PW4074, PW4077, PW4077D, PW4084D, PW4090, PW4090-3, PW4152, PW4156A, PW4158, PW4164, PW4168, PW4168A, PW4460, and PW4462 turbofan engines. The existing AD currently requires initial and repetitive fluorescent penetrant inspections (FPI) for cracks in the blade locking and loading slots of the high-pressure compressor (HPC) drum rotor disk assembly rear drum. Since we issued that AD, Pratt & Whitney has developed a redesigned HPC drum rotor disk assembly for certain affected engine models. This proposed AD would also require replacement of the 13th, 14th, and 15th stage HPC seals as an additional action and would add an optional terminating action to the repetitive inspection requirements by allowing replacement of the entire HPC drum rotor disk assembly. We are proposing this AD to prevent failure of the HPC drum rotor disk assembly, which could lead to an uncontained engine failure, and damage to the airplane.
Amendment of Restricted Area R-2101; Anniston Army Depot, AL
This action amends the description of restricted area R-2101, Anniston Army Depot, AL, by removing the abbreviation ``CST'' from the time of designation, and by including a controlling agency for the restricted area. This amendment does not change the dimensions of, or activities conducted within, R-2101.
Proposed Amendment of Air Traffic Service Routes; Southwestern United States
This action corrects the description of VOR Federal airway V- 16 to include a previous amendment to the description that was inadvertently omitted in the NPRM.
Thirtieth Meeting: RTCA Special Committee 206, Aeronautical Information and Meteorological Data Link Services
The FAA is issuing this notice to advise the public of the thirtieth meeting of RTCA Special Committee 206, Aeronautical Information and Meteorological Data Link Services.
Operating Limitations at New York LaGuardia Airport; Technical Amendment
The FAA is correcting a notice of extension to the order published on April 4, 2011 (76 FR 18616). In that notice, the FAA extended the order limiting operations at LaGuardia Airport until the final Congestion Management Rule for LaGuardia Airport, John F. Kennedy International Airport, and Newark Liberty International Airport becomes effective but not later than October 26, 2013. This document corrects errors in the amended order text of that document.
Proposed Establishment of Class E Airspace; Apopka, FL
This action proposes to establish Class E Airspace at Apopka, FL, to accommodate the Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures at Orlando Apopka Airport. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.
Proposed Establishment of Class E Airspace; Quakertown, PA
This action proposes to establish Class E Airspace at Quakertown, PA, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures at Quakertown Airport. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.
Airworthiness Directives; International Aero Engines AG Turbofan Engines
We are superseding an existing airworthiness directive (AD) for all International Aero Engines AG (IAE) V2500-A1, V2525-D5 and V2528-D5 turbofan engines, and certain serial numbers (S/Ns) of IAE V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, and V2533-A5 turbofan engines. That AD currently requires initial and repetitive ultrasonic inspections (USIs) of certain high-pressure compressor (HPC) stage 3 to 8 drums, and replacement of drum attachment nuts. This new AD expands the affected population for initial and repetitive inspections of the HPC stage 3 to 8 drum, introduces an eddy current inspection (ECI) procedure, and requires additional cleaning and repetitive USI of some HPC stage 3 to 8 drums. We are issuing this AD to prevent uncontained failure of the HPC stage 3 to 8 drum, which could result in damage to the airplane.
Airworthiness Directives; Agusta S.p.A. Helicopters
We propose to adopt a new airworthiness directive (AD) for certain Agusta S.p.A. (Agusta) Model AW139 helicopters. This proposed AD is prompted by the discovery of improper installation of solder splices on the co-pilot audio system causing intermittent noise through the audio system during flight. The proposed actions are intended to prevent degradation and complete loss of communications between the pilot and co-pilot during flight, impairing the co-pilot's capability to react immediately to operational difficulties, which could lead to subsequent loss of control of the helicopter.
Living History Flight Experience (LHFE)-Exemptions for Passenger Carrying Operations Conducted for Compensation and Hire in Other Than Standard Category Aircraft
The FAA is announcing public meetings to gather additional technical input on the subject of exemptions relating to the LHFE. Input gathered will aid in developing future FAA guidance for evaluating LHFE petitions for exemption. Prior to the public meetings, the FAA is seeking public comment on the guidance.
Sec. 221 Public Private Partnerships Public Meeting
The FAA is conducting a public meeting on May 30 to seek initial input from interested stakeholders about program design and implementation of an equipage incentives program for commercial aircraft and general aviation to equip their aircraft with Next Generation Air Transportation (NextGen) capabilities, pursuant to the FAA's authority in the FAA Modernization and Reform Act of 2012 (sec. 221). The statute requires that such a program be based on public- private partnership (PPP) principles and maximize the use of private sector capital. The purpose of this meeting is to serve as an information sharing session. The FAA is interested in engaging stakeholders and potential public-private partners in the process of developing an effective public-private partnership equipage incentive program. This notice is for the initial meeting. A subsequent meeting will be planned within 90 days of the May 30 meeting after FAA has assessed stakeholder comments and feedback and further solidified its policy on how to implement a PPP equipage incentives program.
Airport Improvement Program (AIP) Use of Mineral Revenue at Certain Airports
On February 14, 2012, the FAA Modernization and Reform Act of 2012 (FMRA) was signed into law (Pub. L. 112-95). Section 813 permits the Administrator of the Federal Aviation Administration (FAA) to declare certain revenue derived from or generated by mineral extraction, production, lease, or other means at a general aviation airport to be revenue greater than the amount needed to carry out the five-year projected maintenance needs of the airport in order to comply with the applicable design and safety standards of the Administration. Although the FMRA directed the FAA to promulgate regulations to carry out Section 813 not later than 90 days after the date of enactment, the authorizing committees agreed to support the FAA's request to issue guidance in lieu of a formal rulemaking due to the time limits imposed by the statute. This notice contains the FAA's proposed guidance developed to carry out Section 813 and offers the public an opportunity to comment.
Airworthiness Directives; Agusta S.p.A. Helicopters
We propose to adopt a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109E and Model A109S helicopters with certain lower semichannel assemblies installed. This proposed AD results from reported cases of damage to the main drive shaft caused by improperly secured metallic spacers on some A109 model helicopters. This proposed AD would require a one-time inspection of the lower semichannel assemblies to determine if metallic spacers are installed. If the metallic spacers are installed, this proposed AD would require an inspection for the correct installation of the metallic spacers on the semichannels and for the correct seating of the gaskets. If the metallic spacers are not installed with rivets, the lower semichannel assemblies would be required to be modified, and the main drive shaft would be inspected for damage. The actions specified by this proposed AD are intended to detect missing spacer rivets, which could allow the metallic spacers to rotate and lead to damage and failure of the main drive shaft, and subsequent loss of helicopter control.
Airworthiness Directives; Bell Helicopter Textron Helicopters
We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron (BHT) Model 412, 412EP, and 412CF helicopters. This proposed AD is prompted by a reported failure of a collective lever. These proposed actions are intended to detect a crack in the collective lever, which could lead to failure of the collective lever and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter Deutschland Helicopters
We propose to adopt a new airworthiness directive (AD) for all Eurocopter Deutschland GmbH Model MBB-BK117 C-2 helicopters with certain Generator Control Units (GCU) installed. This proposed AD is prompted by reports of internal short circuits in certain GCUs. The proposed actions are intended to replace any affected GCUs to prevent a short circuit, which could result in a loss of electrical generating power, loss of systems required for continued safe flight and landing, and subsequent loss of control of the helicopter.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4-600 and A300 B4-600R, Model A300, and Model A310 series airplanes. This proposed AD was prompted by reports of fatigue cracking in the crossbeams at the junction of the actuator beam of the lower deck cargo door. This proposed AD would require repetitive inspections of the crossbeams of certain fuselage frames, and repair if necessary. We are proposing this AD to detect and correct cracking of the crossbeams at the junction of the actuator beam of the lower deck cargo door, which could result in failure to withstand ultimate load conditions, and consequent reduced structural integrity of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are superseding an existing airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. That AD currently requires a one- time inspection of the main landing gear (MLG) shock strut assemblies for part and serial numbers; for certain MLG shock strut assemblies, a one-time inspection of the torque link apex joint, and corrective actions if necessary; and, for certain MLG shock strut assemblies, replacement or rework of the apex nut. This new AD continues to require the actions in the existing AD, and adds the previously omitted part and serial numbers. This AD was prompted by reports of loose or detached main landing gear (MLG) torque link apex pin locking plate and the locking plate retainer bolt in the torque link apex joint. We are issuing this AD to detect and correct improper assembly and damage of the MLG torque link apex joint, which could cause heavy vibration during landing, consequent damage to MLG components, and subsequent collapse of the MLG.
Amendment of Class E Airspace; Rock Springs, WY
This action amends Class E airspace at Rock Springs-Sweetwater County Airport, Rock Springs, WY. Decommissioning of the Rock Springs Tactical Air Navigation System (TACAN) has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also adjusts the geographic coordinates of the airport.
Airworthiness Directives; BAE SYSTEMS (Operations) Limited Airplanes
We propose to adopt a new airworthiness directive (AD) for all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. This proposed AD was prompted by reports that the fire extinguisher in the toilet vanity unit needs to be mounted vertically rather than horizontally. This proposed AD would require inspecting to determine if a certain fire extinguisher bottle is installed, and repositioning the affected fire extinguisher bottle to the vertical position. We are proposing 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.
Establishment of Class E Airspace; Freer, TX
This action establishes Class E airspace at Freer, TX. Controlled airspace is necessary to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at Seven C's Ranch Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.
Amendment of Class E Airspace; Baraboo, WI
This action amends Class E airspace at Baraboo, WI. Additional controlled airspace is necessary to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at Reedsburg Municipal Airport. The geographic coordinates of the airport also are adjusted. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport. The Airspace Docket No. is corrected to 11-AGL-29.
Amendment of Class E Airspace; Maryville, MO
This action amends Class E airspace for Maryville, MO. Decommissioning of the Emville non-directional beacon (NDB) at Northwest Missouri Regional Airport has made this action necessary to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport. The geographic coordinates of the airport also are adjusted.
