Federal Aviation Administration June 2009 – Federal Register Recent Federal Regulation Documents

This action establishes a high altitude area navigation (RNAV) route, designated Q-42, extending between the New York-Philadelphia area and the Kirksville, MO, very high frequency omnidirectional range/ tactical air navigation (VORTAC) facility. The route will streamline RNAV procedures in the east-central United States by creating a route parallel to the existing Jet Route J-80. This action will help alleviate departure delay issues for westbound aircraft flying from the New York and Philadelphia areas.

This action amends Class E airspace at Ada, OK. Additional controlled airspace is necessary to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAP) at Ada Municipal Airport, Ada, OK. This action also updates the geographic coordinates of the airport to coincide with the FAA's National Aeronautical Charting Office. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at Ada Municipal Airport.

This action amends Class E airspace at Mansfield, OH. Additional controlled airspace is necessary to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAP) at Mansfield Lahm Regional Airport, Mansfield, OH. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at Mansfield Lahm Regional Airport. This action also updates the airport name to Mansfield Lahm Regional Airport and updates the geographic coordinates of Shelby Community Airport and Willard Airport.

The Federal Aviation Administration (FAA) is considering a proposal to change a portion of the airport from aeronautical use to non-aeronautical use and to authorize the release of 37.016 acres of airport property for the proposed development bulk warehouse/ distribution facilities as a component of the Rickenbacker Global Logistics Park. The land was acquired by the Rickenbacker Port Authority through two Quitclaim Deeds dated March 30, 1984 from the Administrator of General Services for the United States of America and May 11, 1999 from the United States of America, acting by and through the Secretary of the Air Force. There are no impacts to the airport by allowing the airport to dispose of the property. Approval does not constitute a commitment by the FAA to financially assist in the disposal of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the disposal of the airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999.

We are adopting a new airworthiness directive (AD) for certain Boeing Model 747-400 and -400F series airplanes. This AD requires modifying certain thrust reverser control system wiring to the flap control unit (FCU). This AD results from a report of automatic retraction of the leading edge flaps during takeoff due to indications transmitted to the FCU from the thrust reverser control system. We are issuing this AD to prevent automatic retraction of the leading edge flaps during takeoff, which could result in reduced climb performance and consequent collision with terrain and obstacles or forced landing of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for International Aero Engines AG (IAE) V2500-A1, V2527E-A5, V2530-A5, and V2528-D5 turbofan engines. This proposed AD would require reducing the published life limit of certain high-pressure compressor (HPC) stage 9-12 disc assemblies. This proposed AD would also remove from service those HPC stage 9-12 disc assemblies using a drawdown schedule. This proposed AD results from IAE updating the low-cycle-fatigue (LCF) life analysis for certain HPC stage 9-12 disc assemblies. We are proposing this AD to prevent an uncontained failure of the HPC stage 9- 12 disc assembly, resulting in an in-flight engine shutdown and possible damage to the airplane.

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747 airplanes. That AD currently requires repetitive inspections to detect evidence of wear damage in the area at the interface between the vertical stabilizer seal and fuselage skin, and corrective actions, if necessary. The existing AD also provides for an optional terminating action for the repetitive inspections. For all Boeing Model 747-100, 747-100B, 747- 100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes, this new AD requires repetitive inspections for wear damage and cracks of the fuselage skin in the interface area of the vertical stabilizer seal and fuselage skin, a detailed inspection for wear damage and cracks of the surface of any skin repair doubler in the area, and corrective actions if necessary. For airplanes on which the fuselage skin has been blended to remove wear damage, this new AD requires repetitive external detailed inspections or high frequency eddy current inspections for cracks of the blended area of the fuselage skin, and corrective actions if necessary. This AD results from reports of wear damage on airplanes with fewer than 8,000 total flight cycles. In addition, there have been three reports of skin wear damage on airplanes that applied Boeing Material Specifications 10-86 Teflon-filled coating (terminating action per the existing AD). We are issuing this AD to detect and correct wear damage and cracks of the fuselage skin in the interface area of the vertical stabilizer seal and fuselage skin in sections 46 and 48, which could cause in-flight depressurization of the airplane.

We are adopting a new airworthiness directive (AD) for all McDonnell Douglas Model MD-90-30 airplanes. This AD requires repetitive inspections for cracks of the upper aft skin panels on the horizontal stabilizer, and related investigative and corrective actions if necessary. This AD results from a report of cracks found in the aft skin panels on the upper right side of the horizontal stabilizer at the aft inboard corner. We are issuing this AD to detect and correct cracks in the fail-safe structure that may not be able to sustain limit load, which could result in the loss of overall structural integrity of the horizontal stabilizer.

The FAA proposes to rule and invites public comment on the release of land at Pocahontas Municipal Airport under the provisions of Title 49, U.S.C. 47153(c).

We propose to adopt a new airworthiness directive (AD) for all Boeing Model 777 series airplanes. This proposed AD would require inspections 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. This proposed AD results from reports of scribe lines found at lap joints and butt joints, around external doublers, and at locations where external decals had been cut. 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.

The FAA is issuing this notice to advise the public of a meeting of the NextGen Mid-Term Implementation Task Force.

The FAA is correcting airworthiness directive (AD) 2009-04-18, which was previously published in the Federal Register. That AD applies to PW models JT9D-7, -7A, -7AH, -7H, -7F, and -7J turbofan engines. The two references to the engine manual in paragraph (h) and in Table 1, are incomplete. This document corrects those references. In all other respects, the original document remains the same.

This action proposes to modify Class E airspace at Lake Havasu City, AZ. Additional controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at Lake Havasu City Airport, Lake Havasu, AZ. The FAA is proposing this action to enhance the safety and management of aircraft operations at Lake Havasu City Airport, Lake Havasu, AZ.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

This action proposes to establish Class D airspace at Arlington, TX. Establishment of an air traffic control tower at Arlington Municipal Airport has made this action necessary for the safety and management of Instrument Flight Rules (IFR) aircraft operations at Arlington Municipal Airport.

This action proposes to establish Class E airspace at Neligh, NE. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Antelope County Airport, Neligh, NE. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at Antelope County Airport.

The FAA proposes to adopt a new airworthiness directive (AD) for General Electric Company (GE) GE90-110B1, GE90-113B, and GE90-115B series turbofan engines with stage 6 low-pressure turbine (LPT) blades, part number (P/N) 1765M37P03 or P/N 1765M37P04, installed. This proposed AD would require initial and repetitive inspections for shroud interlock wear of the stage 6 LPT blades. This proposed AD would also require replacing those blades with stage 6 LPT blades eligible for installation at the next engine shop visit as terminating action to the repetitive blade inspections. This proposed AD results from eight reports of GE90-115B stage 6 LPT single-blade separation events. We are proposing this AD to prevent failure of stage 6 LPT blades, which could result in uncontained engine failure and damage to the airplane.

We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-200B, 747-200C, 747-200F, and 747SR series airplanes. This proposed AD would require a one-time general visual inspection for missing fasteners in certain stringer-to- stringer clip joints at the station (STA) 760 through STA 940 frames, and related investigative and corrective actions if necessary. This proposed AD results from a report of broken and cracked frame shear ties, cracks on the frame doubler and frame web, and missing fasteners in the stringer (S)-10L stringer-to-stringer clip joint at the STA 820 frame. We are proposing this AD to detect and correct missing fasteners in the stringer-to-stringer clip joints, which could result in shear tie and skin cracks and rapid in-flight decompression of the airplane.

This notice announces the issuance of Advisory Circular (AC) 33-7A, Guidance for 30-Second and 2-Minute One-Engine-Inoperative (OEI) Ratings for Rotorcraft Turbine Engines. This AC provides guidance and acceptable means, but not the only means, for demonstrating compliance with the specific requirements applicable to 30-second and 2-minute OEI rotorcraft turbine engine ratings in part 33 of Title 14 of the Code of Federal Regulations (14 CFR part 33).

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.

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:

The FAA is superseding an existing airworthiness directive (AD), which applies to all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. That AD currently requires repetitive inspections for corrosion of frames 15, 18, 41, and 43 and applicable related investigative and corrective actions. The existing AD also provides an optional action that would extend the repetitive inspection interval. This new AD also requires a high frequency eddy current inspection for corrosion of the outer frame flanges and door hinge bosses of frames 15, 18, 41, and 43. This AD results from a report indicating that corrosion has been detected in the outer frame flanges and door hinge bosses during scheduled maintenance. We are issuing this AD to prevent reduced structural integrity of the airplane.
