Federal Aviation Administration 2011 – Federal Register Recent Federal Regulation Documents

This action establishes Class E Airspace at Nahunta, GA, to accommodate the new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures serving Brantley County Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations within the National Airspace System. This action also makes a minor adjustment to the geographic coordinates of the airport.

This action establishes Class E airspace at Palmyra, PA, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures at Reigle Field. This action enhances the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also makes a minor adjustment to the geographic coordinates of the airport.

We propose to supersede an existing airworthiness directive (AD) that applies to all CPAC, Inc. (type certificate formerly held by Commander Aircraft Corporation, Gulfstream Aerospace Corporation, and Rockwell International) Models 112, 112B, 112TC, 112TCA, 114, 114A, 114B, and 114TC airplanes. The existing AD currently requires a one- time inspection of the elevator spar for cracks and, if any crack is found, either replace with a serviceable elevator spar that is found free of cracks or repair/modify the elevator spar with an FAA-approved method. That AD also requires reporting to the FAA the results of the inspection. Since we issued that AD, using the data collected through the reporting requirement, we have determined there is a need for continued inspections. This proposed AD would require repetitive inspections of the elevator spar for cracks and, if any crack is found, either replace with a serviceable elevator spar that is free of any cracks and/or corrosion or repair/modify the elevator spar with an FAA- approved procedure. We are proposing this AD to correct the unsafe condition on these products.

This action amends the time of designation for restricted areas R-5314A, B, C, D, E, F, H, and J in Dare County, NC, by removing the specific published times on Saturday and Sunday. This change reflects current utilization of the restricted areas and provides increased public access to the area on weekends.

Under the provisions of title 49, U.S.C. Section 47153(c), notice is being given that the FAA is considering a request from the Laurinburg-Maxton Airport Commission to waive the requirement that approximately 20.26 acres of airport property, located at the Laurinburg-Maxton Airport, be used for aeronautical purposes.

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to the products listed above. The effective date in paragraph (a) of the Amended section of the AD is incorrect. This document corrects that error. In all other respects, the original document remains the same.

This 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.

These special conditions are issued for the Gulfstream Aerospace LP (GALP) model G280 airplane. This airplane will have a novel or unusual design feature associated with engine torque loads imposed by sudden engine stoppage. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. 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 action proposes special conditions for the Learjet Model LJ-200-1A10 airplane. This airplane will have a novel or unusual design feature associated with hydrophobic windshield coatings in lieu of windshield wipers. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed 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.

We propose to revise an existing airworthiness directive (AD) that applies to all Eclipse Aerospace, Inc. Model EA500 airplanes equipped with Pratt & Whitney Canada, Corp. (P&WC) Model PW610F-A engines. The existing AD currently requires incorporating an operating limitation of a maximum operating altitude of 30,000 feet into Section 2, Limitations, of the airplane flight manual (AFM). Since we issued that AD, P&WC has developed a design change for the combustion chamber liner assembly. This proposed AD would retain the requirements of the current AD, clarify the engine applicability, and allow the option of incorporating the design change to terminate the current operating limitation and restore the original certificated maximum operating altitude of 41,000 feet. We are proposing this AD to correct the unsafe condition on these products.

This notice announces the FAA's cancellation of TSO-C129a, Airborne Supplemental Navigation Equipment Using the Global Positioning System (GPS) effective October 21, 2011. TSO cancellation will not affect production according to an existing TSO authorization (TSOA). Articles produced under an existing TSOA can still be installed according to existing airworthiness approvals and applications for new airworthiness approvals will still be processed. The effect of the cancelled TSO will result in no new TSO-C129a design or production approvals. However, we will accept applications for new TSO-C129a TSO Authorizations (TSOA) until October 21, 2012 if we know that you were working toward a TSO-C129a approval prior to October 21, 2011.

The FAA is issuing this notice to advise the public that a Record of Decision (ROD), resulting from an Environmental Impact Statement (EIS) Re-evaluation has been prepared for Sikorsky Memorial Airport in Stratford, Connecticut.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require installing an automatic shutoff system for the center and auxiliary tank fuel boost pumps, as applicable, and installing a placard in the airplane flight deck if necessary; replacing the P5-2 fuel system module assembly; and installing the un-commanded on (UCO) protection system for the center and auxiliary tank fuel boost pumps, as applicable. This proposed AD would also require revisions to the Limitations and Normal Procedures sections of the airplane flight manual to advise the flightcrew of certain operating restrictions for airplanes equipped with an automatic shutoff system. This proposed AD would also require revising the maintenance program by incorporating new airworthiness limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This proposed AD was prompted by fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent operation of the center and auxiliary tank fuel boost pumps with continuous low pressure, which could lead to friction sparks or overheating in the fuel pump inlet that could create a potential ignition source inside the center and auxiliary fuel tanks. These conditions, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

We are adopting a new airworthiness directive (AD) for Diamond Aircraft Industries GmbH Model (Diamond) DA 40 airplanes equipped with cabin air conditioning vapor cycle system (VCS) installed per STC SA03674AT held by Premier Aircraft Services (originally held by DER Services, Inc.) following DER Services Master Document List MDL-2006- 020-1, Revision C, dated February 3, 2009; Revision D, dated April 22, 2009; Revision E, dated May 12, 2010; or Revision F, dated July 6, 2010. This AD was prompted by reports of damage around the VCS compressor mounting areas found during maintenance inspections. This AD requires deactivation of the VCS, removal of the compressor and bracket, and revision to the airplane weight and balance. We are issuing this AD to correct the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:

The MCAI describes the unsafe condition as:

The FAA is superseding an existing airworthiness directive (AD) that applies to all Model 767 airplanes. The existing AD currently requires repetitive detailed and high frequency eddy current (HFEC) inspections of the station (STA) 1809.5 bulkhead for cracking, and corrective actions if necessary. This AD expands the inspection area to include the vertical inner chord at STA 1809.5. This AD results from reported fatigue cracking in the vertical inner chord and the forward outer chord while doing the detailed inspection of the horizontal inner chord at STA 1809.5. We are issuing this AD to detect and correct fatigue cracking in the bulkhead structure at STA 1809.5 and the vertical inner chord at STA 1809.5, which could result in failure of the bulkhead structure for carrying the flight loads of the horizontal stabilizer, and consequent loss of controllability of the airplane.

We propose to adopt a new airworthiness directive (AD), for certain Airbus Model A300 B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4- 203 airplanes and Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, and F4-605R airplanes, that would supersede an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product.

We propose to adopt a new airworthiness directive (AD) for certain Model 767-200 and 767-300 series airplanes. This proposed AD would require installing cargo bulkhead supports, ceiling supports, secondary dam support, drainage tubing, and ceiling panels to the forward lower lobe in the forward cargo compartment. This proposed AD was prompted by reports of water accumulation in the forward lower lobe of the forward cargo compartment. We are proposing this AD to prevent water from accumulating in the forward lower lobe of the forward cargo compartment and entering the adjacent electronic equipment bay, which could result in an electrical short and the potential loss of several functions essential for safe flight.

We are revising an earlier proposed airworthiness directive (AD) for all Model 767 airplanes. That NPRM proposed repetitive inspections to detect fatigue cracking in the wing skin, and corrective actions if necessary. That NPRM was prompted by reports of cracking in the upper wing skin at the fastener holes common to the inboard and outboard pitch load fittings of the front spar which could result in the loss of the strut-to-wing upper link load path and possible separation of a strut and engine from the airplane during flight. This action revises that NPRM by reducing compliance times. We are proposing this supplemental NPRM to correct the unsafe condition on these products. Since these actions 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 these proposed changes.

We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 747-400 series airplanes. This proposed AD was prompted by reports of water leaking into electrical and electronic equipment in the main equipment center, which could result in an electrical short and potential loss of several functions essential for safe flight. This proposed AD would require 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 proposing this AD to correct the unsafe condition on these products.

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to Viking Air Limited Model DHC-3 (Otter) airplanes equipped with a Honeywell TPE331- 10 or -12JR turboprop engine installed per STC SA09866SC (Texas Turbines Conversions, Inc.). The wording on how the AD is justified and the wording of the temporary placard need clarification. The clarification does not affect the actions of the AD. This document makes this clarification. In all other respects, the original document remains the same.

We are revising an earlier proposed airworthiness directive (AD) for certain Aviation Communication & Surveillance Systems (ACSS) traffic alert and collision avoidance system (TCAS) units installed on but not limited to various transport and small airplanes. That NPRM proposed to require upgrading software. That NPRM was prompted by reports of anomalies with TCAS units during a flight test over a high density airport. The TCAS units dropped several reduced surveillance aircraft tracks because of interference limiting. This action revises that NPRM by proposing to require new updated software for certain TCAS units. We are proposing this supplemental NPRM to correct the unsafe condition on these products. Since these actions 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 these proposed changes.

This document announces the availability of and request for public comments on the proposed policy statement addressing the action taken by some Design Approval Holders (DAH) restricting the availability, distribution, and use of Instructions (ICA) through contractual agreements or restrictive language in the actual ICA.
