Federal Aviation Administration August 26, 2011 – Federal Register Recent Federal Regulation Documents

This action proposes to amend Class E airspace at Centerville, IA. Decommissioning of the Centerville non directional beacon (NDB) and cancellation of the NDB approach at Centerville Municipal Airport, as well as the addition of a new COPTER RNAV standard instrument approach procedure (SIAP) at Mercy Medical Center-Centerville Heliport, have made this action necessary to enhance the safety and management of Instrument Flight Rules (IFR) operations within the National Airspace System.

This action proposes to amend Class E airspace at Carroll, IA. Decommissioning of the Carroll non-directional beacon (NDB) at Arthur N. Neu Airport, Carroll, IA, has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport.

This action proposes to amend Class E airspace in the Alice, TX, area. Cancellation of all standard instrument approach procedures at Old Hoppe Place Airport, Agua Dulce, TX, has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations in the Alice, TX, area.

This notice announces the bi-annual meeting of the Federal Aviation Administration (FAA) Aeronautical Charting Forum (ACF) to discuss informational content and design of aeronautical charts and related products, as well as instrument flight procedures development policy and design criteria.

We propose to adopt a new airworthiness directive (AD) for the products listed above 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. The MCAI describes the unsafe condition as: * * * * * * * * BAE Systems (Operations) Limited has amended the AMM [aircraft maintenance manual] to remove the life limits on shock absorber assemblies, but not the individual shock absorber components, and amend the life limits on the different standards of Main Landing Gear (MLG) Up-Locks and MLG Door Up-Locks in sub- chapter 05-10-15. In addition BAE Systems has amended Chapter 05-10- 15 of the AMM to introduce and amend life limits on MLG components. * * * * * The unsafe condition is fatigue cracking of certain structural elements which could adversely affect the structural integrity of these airplanes. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 relating to airspace designations to reflect the approval by the Director of the Federal Register of the incorporation by reference of FAA Order 7400.9V, Airspace Designations and Reporting Points. This action also explains the procedures the FAA will use to amend the listings of Class A, B, C, D, and E airspace areas; air traffic service routes; and reporting points incorporated by reference.

This action proposes to amend Class E airspace at Winters, TX. Decommissioning of the Winters RBN and cancellation of the non- directional radio beacon (NDB) Standard Instrument Approach Procedures (SIAP), as well as the addition of new area navigation (RNAV) SIAPs, have made this action necessary to enhance the safety and management of Instrument Flight Rules (IFR) operations at Winters Municipal Airport.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval for to renew an information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on June 21, 2011, vol. 76, no. 119, page 36169-36170. This collection covers the reporting of unauthorized illumination of aircraft by lasers.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval for to renew an information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on June 21, 2011, vol. 76, no. 119, page 36167. The information collected is used by the FAA to register aircraft or hold an aircraft in trust. The information required to register and prove ownership of an aircraft is required by any person wishing to register an aircraft.

We are superseding an existing airworthiness directive (AD) that applies to 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:

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires installation of an automatic shutoff system for the center tank fuel boost pumps, and installation of a placard in the airplane flight deck if necessary. This AD also requires 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 automated center tank fuel pump shutoff control. This AD further requires installation of a secondary control relay for the electrical control circuit of each of the two center tank fuel boost pumps. Additionally, this AD requires a revision to the maintenance program to incorporate Airworthiness Limitation (AWL) No. 28-AWL-23. This AD also provides an option of installation and maintenance of universal fault interrupters using a certain supplemental type certificate, which terminates certain requirements of this AD. This AD was prompted by fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent center tank fuel pump operation 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 fuel tank. These conditions, in combination with flammable fuel vapors, could result in a center fuel tank explosion and consequent loss of the airplane.

This amendment supersedes an existing emergency airworthiness directive (EAD) for the specified Agusta S.p.A. (Agusta) model helicopters. That EAD currently requires inspecting the main rotor scissor fitting assembly to determine if there are 2 washers installed under the head of each main rotor scissor fitting assembly fixing bolt (fixing bolt). If there are not 2 washers installed under the head of each fixing bolt, that EAD requires replacing each fixing bolt and installing 2 washers under the head of each fixing bolt. This superseding airworthiness directive (AD) is prompted by the determination that a wrong part number (P/N) for the main rotor scissor fitting assembly was listed in the EAD. This AD retains the requirements of the EAD and corrects a P/N for the main rotor scissor fitting assembly. The actions specified by this AD are intended to prevent a crack in a fixing bolt, failure of a fixing bolt, and subsequent loss of control of the helicopter.

This amendment adopts a new airworthiness directive (AD) for ECF Model EC120B helicopters. This action requires inserting an emergency procedure appendix from an ECF Emergency Alert Service Bulletin into the Rotorcraft Flight Manual (RFM). This action also requires modifying the emergency switch electrical wiring and performing tests to ensure correct operation of the emergency switch. This action also requires removing the emergency procedure appendix from the RFM after modifying the emergency switch electrical wiring and performing tests to ensure correct operation. This amendment is prompted by the discovery that simultaneously setting the emergency switch to the low position ``CUT-OFF'' and the generator (GENE) pushbutton to ``OFF'' position caused the starter-generator to restart. Investigation revealed that cross-wiring at the emergency switch caused this malfunction. This condition, if not corrected, could lead to the inability to isolate electrical equipment during an emergency, creating the risk of an uncontrolled electrical fire and subsequent loss of control of the helicopter.
