Department of Transportation June 2006 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) that supersedes AD 2005-26-53, which applies to certain Pacific Aerospace Corporation Ltd. (PAC) 750XL airplanes. AD 2005-26-53 currently requires you to insert text into the Limitations Section of the Airplane Flight Manual (AFM) that reduces the maximum takeoff weight from 7,500 pounds to 7,125 pounds. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand and the FAA's decision that the actions correct an unsafe condition. Consequently, this AD would require you to remove rivets that have not been fully age hardened and replace them with bolts, washers, and nuts in specific locations where reduction in rivet strength affects overall structural capability. This AD retains the actions of the previous AD until the rivets are replaced with the bolts, washers, and nuts. We are issuing this AD so that wing ultimate load requirements are met. If wing ultimate load requirements are not met, wing failure could result with consequent loss of control of the airplane.

We propose to adopt a new airworthiness directive (AD) for certain Air Tractor, Inc. Models AT-802 and AT-802A airplanes. This proposed AD would require you to repetitively inspect the attach angles on the firewall mounted hopper rinse tank shelf for damage and/or cracks and replace damaged and/or cracked attach angles. Replacing the attach angles with steel attach angles would terminate the proposed repetitive inspection requirement. Reports of an uncommanded change in the engine power setting caused by separation of the hopper rinse tank shelf from the firewall prompted this proposed AD. We are proposing this AD to detect and correct damage and/or cracks in the attach angles on the firewall mounted hopper rinse tank shelf, which could result in failure of the attach angles. This failure could lead to shelf movement under maneuver load and shifting of the engine power cables, which could result in an uncommanded engine power setting change.

Pursuant to FAA's rulemaking provisions governing the application, processing, and disposition of petitions for exemption part 11 of Title 14, Code of Federal Regulations (14 CFR), this notice contains a summary of certain petitions seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of any petition or its final disposition.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757 airplanes. This AD requires, for certain airplanes, reworking the spar bonding path and reapplying sealant; and, for certain other airplanes, testing the electrical bond between the engine fuel feed hose and the wing front spar and, if applicable, reworking the spar bonding path and reapplying sealant. This AD also requires, for all airplanes, an inspection to ensure the electrical bonding jumper is installed between the engine fuel feed tube and the adjacent wing station. This AD also requires operators that may have installed an incorrect O-ring to install the correct part and do a re- test. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent arcing or sparking at the interface between the bulkhead fittings of the engine fuel feed tube and the front spar during a lightning strike, which could provide a possible ignition source for the fuel vapor inside the fuel tank and result in a fuel tank explosion.

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 727-200 series airplanes. That AD currently requires initial and repetitive inspections for cracks in the forward frame of the No. 3 cargo door cutout; and corrective actions, if necessary. The existing AD also provides for an optional structural modification, which terminates the repetitive inspections. This new AD reduces the compliance time for the initial inspections and adds an optional method of inspection for both the initial and repetitive inspections. This AD also adds initial and repetitive inspections of an additional area, and repair if necessary. Additionally, this AD clarifies that the previously optional structural modification is now required by other rulemaking. This AD results from additional reports of cracking in the forward frame of the No. 3 cargo door cutout. We are issuing this AD to detect and correct cracking of the forward frame and fuselage skin of the No. 3 cargo door cutout, which could result in failure of the frame and skin, and consequent rapid decompression of the airplane.

This action proposes to revise Class E airspace at Barter Island, AK. Two new Standard Instrument Approach Procedures (SIAPs) are being developed and one SIAP is being amended for the Barter Island Airport. Adoption of this proposal would result in amending Class E airspace upward from 700 feet (ft.) and 1,200 ft. above the surface at Barter Island, AK.

DOT intends to establish a system of records under the Privacy Act of 1974.

This notice announces actions taken by the FHWA and other Federal agencies that are final within the meaning of 23 U.S.C. 139(l)(1). The actions relate to various proposed highway projects in the State of South Carolina. Those actions grant licenses, permits, and approvals for the projects.

FMCSA announces its plan to request the Office of Management and Budget's (OMB) approval of an information collection (IC) associated with the Agency's Medical Examiner Performance Study. This information collection effort would gather survey, on-site observation, and interview data on the decisionmaking process of medical examiners (MEs) (which include, but are not limited to, medical doctors, doctors of osteopathy, doctors of chiropractic, physician assistants, and advanced practice nurses) who conduct FMCSA physical examinations of commercial motor vehicle (CMV) drivers. The survey would consist of a sample of the several different practitioner types for the purpose of assessing ME knowledge of key elements required for CMV interstate driver certification. The survey would also provide these medical practitioners with an opportunity to report perceived difficulties associated with the CMV driver physical examination process. Site visits would allow for the interview and observation of medical examiners during the actual physical examination and certification decisionmaking process.

The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by the City of Scottsdale, Arizona under the provisions of Title I of the Aviation Safety and Noise Abatement Act, as amended, (Public Law 96-193) (hereinafter referred to as ``the Act'') and 14 CFR part 150. These findings are made in recognition of the description of Federal and nonfederal responsibilities in Senate Report No. 96-52 (1980). On January 21, 2005, the FAA determined that the noise exposure maps submitted by the City of Scottsdale under Part 150 were in compliance with applicable requirements.

This action corrects an error in the airspace description contained in a Final Rule that was published in the Federal Register on Monday, April 24, 2006 (71 FR 20871). Airspace Docket No. 06-AAL-06.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

The FHWA is seeking public input on preliminary list of elements to be excluded from exemptions of the Interstate Highway System from consideration as historic property under the provisions of section 106 of the National Historic Preservation Act and section 4(f) of the Department of Transportation Act of 1966.\1\ This list is available at https://www.environment.fhwa.dot.gov/histpres/index.asp. This notice contains a link to and the process for interested members of the public to comment on the preliminary list of elements to be excluded from the respective exemptions of the Interstate Highway System from consideration as historic property under the authorities cited above. Comments received from the public will be factored into development of a final list of exceptional elements of the Interstate System.

The FAA proposes to supersede an existing airworthiness directive (AD) for CFM International CFM56-5 and -5B series turbofan engines. That AD currently requires exhaust gas temperature (EGT) harness replacement or the establishment of an EGT baseline and trend monitoring. That AD also requires replacement, if necessary, of certain EGT harnesses and EGT couplings as soon as a slow and continuous EGT drift downward is noticed after the effective date of that AD. This proposed AD would require the same actions but for an increased population of affected EGT harnesses. This proposed AD results from CFM International adding subsequently certified engine models to the list of engines that could have affected harnesses installed. We are proposing this AD to prevent unexpected deterioration of critical rotating engine parts due to higher than desired engine operating EGTs.

These special conditions are issued for the Cessna Aircraft Company, Model 510 airplane. This airplane will have a novel or unusual design feature(s) associated with the use of an electronic engine control system instead of a traditional mechanical control system. 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.

In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), this notice announces that the Information Collection Requirements (ICRs) abstracted below have been forwarded to the Office of Management and Budget (OMB) for review and comment. The ICRs describes the nature of the information collections and their expected burdens. The Federal Register notice with a 60-day comment period soliciting comments on the following collections of information was published on April 7, 2006 (71 FR 17945).

This document tells certain pipeline operators how to submit their written public awareness programs for review. Regulations issued in 2005 provide details about the content of the programs and establish completion dates. The 2002 amendment to the pipeline safety law requires pipeline operators to submit these programs for review and PHMSA has a clearinghouse approach for reviewing interstate and many intrastate operators. This document ensures operators know where and when to submit their programs.

This action proposes to establish 16 VOR Federal Airways (V- 65, V-176, V-383, V-396, V-406, V-410, V-414, V-416, V-418, V-426, V- 467, V-486, V-542, V-584, V-586, and V-609); modify 13 VOR Federal Airways (V-14, V-26, V-40, V-72, V-75, V-90, V-96, V-103, V-116, V-133, V-297, V-435, and V-526); and revoke one VOR Federal Airway (V-42) over the East Central United States in support of the Midwest Airspace Enhancement Plan (MASE). The FAA is proposing this action to enhance safety and to improve the efficient use of the navigable airspace assigned to the Chicago, Cleveland, and Indianapolis Air Route Traffic Control Centers (ARTCC).

In accordance with the procedures governing the application for, and the processing of, special permits from the Department of Transportation's Hazardous Material Regulations (49 CFR part 107, subpart B), notice is hereby given that the Office of Hazardous Materials Safety has received the application described herein. This notice is abbreviated to expedite docketing and public notice. Because the sections affected, modes of transportation, and the nature of application have been shown in earlier Federal Register publications, they are not repeated here. Request of modifications of special permits (e.g., to provide for additional hazardous materials, packaging design changes, additional mode of transportation, etc.) are descried in footnotes to the application number. Application numbers with the suffix ``M'' denote a modification request. These applications have been separated from the new applications for special permits to facilitate processing.

The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 208, Aeronautical Mobile Satellite Services.

The FAA adopts a new airworthiness directive (AD) for General MachineDiecron, Inc. (GMD) actuator nut assembly, part number (P/N) GMD115-810029-17 and P/N GMD115-810029-23, that are installed on certain Raytheon Aircraft Company (Raytheon) (formerly Beech) airplanes that are not equipped with a hydraulic main landing gear (MLG) or modified to a hydraulic MLG. This AD requires you to determine by maintenance records check and/or inspection whether any actuator nut assembly, P/N GMD115-810029-17 or P/N GMD115-810029-23, is installed on the right main MLG actuator, and, if installed, requires you to replace it with a new actuator nut assembly, P/N GMD115-810029-23B or FAA- approved equivalent P/N. This AD results from several reports of failures of the actuator nut assembly, P/N GMD115-810029-17 and P/N GMD115-810029-23. We are issuing this AD to prevent failure of the actuator nut assembly for the right MLG actuator, which could result in failure of the MLG. This failure could prevent the extension or retraction of the MLG.

This document makes a correction to Airworthiness Directive (AD) 2006-10-21. That AD applies to Engine Components Incorporated (ECi) reciprocating engine connecting rods. We published AD 2006-10-21 in the Federal Register on May 18, 2006, (71 FR 28769). An incorrect amendment number exists under the Sec. 39.13 amended heading. This document corrects the amendment number. In all other respects, the original document remains the same.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 airplanes. This AD requires inspecting to determine the part number and serial number of the fuel tank boost pumps and, for airplanes with affected pumps, revising the Airplane Flight Manual (AFM) and the FAA-approved maintenance program. This AD also provides for optional terminating action for compliance with the revisions to the AFM and the maintenance program. This AD results from a report that a fuel tank boost pump failed in service, due to a detached screw of the boost pump housing that created a short circuit between the stator and rotor of the boost pump motor and tripped a circuit breaker. We are issuing this AD to ensure that the flightcrew is aware of procedures to prevent the presence of a combustible air-fuel mixture in the fuel tank boost pump, which, in the event of electrical arcing in the pump motor, could result in an explosion and loss of the airplane.

The FAA is adopting a new airworthiness directive (AD) for all Raytheon Model BAe.125 series 800A (including variants C-29A and U- 125), 800B, 1000A, and 1000B airplanes and Model Hawker 800 (including variant U-125A) and 1000 airplanes; and for certain Raytheon Model HS.125 series 700A and 700B airplanes and Model Hawker 800XP airplanes. This AD requires measuring the resistance of the current limiters for the PE, PS1, and PS2 busses, and replacing a current limiter with a new part if necessary. This AD also requires reporting certain information to the airplane manufacturer. This AD allows a records review for determining if suspect current limiters were installed, which may exempt airplanes from the required measurement. This AD results from reports that certain current limiters have opened within two to four hours after installation. We are issuing this AD to prevent loss of all primary electrical power, which could result in the airplane operating only under emergency power.
