Department of Transportation July 2007 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This proposed AD would require installation of an automatic shutoff system for the center tank fuel boost pumps, installation of a placard in the airplane flight deck if necessary, and concurrent modification of the P5-2 fuel control module assembly. 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 automated center tank fuel pump shutoff control. This proposed AD would also require a revision to the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness to incorporate AWL No. 28-AWL- 19 and No. 28-AWL-23. This proposed AD would also require installation of two secondary override fuel pump control relays to each existing primary override fuel pump control relay for the center fuel tank fuel boost pumps. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing 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 or 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 action corrects a final rule published in the Federal Register June 15, 2007 (72 FR 33151), Airspace Docket No. 06-ASW-1, FAA Docket No. FAA-2006-24926. In that rule, an error was made in the legal description for VOR Federal Airway V-65. Specifically, the description omitted the words ``Sandusky, OH''. This action corrects that error.

This notice proposes to amend Class E5 airspace at Gainesville, FL. An Area Navigation (RNAV) Global Positioning System (GPA) Standard Instrument Approach Procedure (SIAP), helicopter point in space approach, has been developed for Shands Hospital, Gainesville, FL. As a result, controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to contain the SIAP.

This notice proposes to establish Class E5 airspace at Winfield, FL. An Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP), helicopter point in space approach, has been developed for Interstate-10 Rest Stop Heliport, Winfield, FL. As a result, controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to contain the SIAP.

These special conditions are issued for Boeing Model 737 series airplanes. These airplanes will have a novel or unusual design feature(s) associated with seats that include non-traditional, large, non-metallic panels that would affect survivability during a post-crash fire event. 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.

The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 757-200, -200CB, -200PF, and -300 series airplanes. This proposed AD would require 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 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 automated center tank fuel pump shutoff control. This proposed AD would also require a revision to the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness to incorporate AWL No. 28- AWL-20 and No. 28-AWL-26. This proposed AD would also require replacement of the fuel control panel assembly with a modified part, installation of two secondary pump control relays for the center tank fuel pumps, other specified actions, and concurrent modification of the fuel control panel assembly. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing 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 or 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.

The FAA proposes to adopt a new airworthiness directive (AD) for IAE V2500-A1, V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, V2533-A5, V2525-D5, V2528-D5 turbofan engines. This proposed AD would require removing certain No. 4 bearing seal components from service at the next shop visit or by an end date determined by the engine model. This proposed AD results from instances of oil loss from the No. 4 bearing compartment. We are proposing this AD to prevent heat damage to high pressure turbine (HPT) and low pressure turbine (LPT) critical life limited hardware such as the HPT stage 1-2 airseal. Damage to the HPT stage 1-2 airseal could cause uncontained engine failure and damage to the airplane.

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 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 proposes to adopt a new airworthiness directive (AD) for all Viking Air Limited Model DHC-7 airplanes. This proposed AD would require an inspection of certain SM-200 servo drive units (power servo motor and housing assemblies) for certain markings, related investigative action if necessary, and modification if necessary. This proposed AD results from a report that some SM-200 servo drive units that were not in configuration MOD H are installed on Model DHC-7 airplanes. MOD H prevents the internal clutch fasteners from backing out. We are proposing this AD to prevent the possibility of internal clutch fasteners from backing out, which could cause an inadvertent servo engagement and consequent reduced controllability of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 727 airplanes. This proposed AD would require revising the FAA-approved maintenance program by incorporating new airworthiness limitations (AWLs) for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This proposed AD would also require the initial inspection of a certain repetitive AWL inspection to phase in that inspection, and repair if necessary. This proposed AD results from a design review of the fuel tank systems. We are proposing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

We propose to adopt a new airworthiness directive (AD) for the products listed above. 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 proposes to supersede an existing airworthiness directive (AD) for Rolls-Royce Deutschland (RRD) Tay 611-8, Tay 620-15, Tay 650-15, and Tay 651-54 turbofan engines. That AD currently requires initial and repetitive visual inspections of all ice-impact panels and fillers in the low pressure (LP) compressor case for certain conditions and replacing as necessary, any or all panels. This proposed AD would require the same initial and repetitive inspections, provide terminating action to those repetitive actions, and add the Tay 611-8C turbofan engine to the applicability. This proposed AD results from RRD introducing new LP compressor case ice-impact panels with additional retention features, to these Tay turbofan engines. We are proposing this AD to prevent release of ice- impact panels due to improper bonding that can result in loss of thrust in both engines.

The Coast Guard and the Maritime Administration (MARAD) announce the availability of the Draft Environmental Impact Statement (DEIS) for the TORP Terminal LP, Bienville Offshore Energy Terminal Liquefied Natural Gas Deepwater Port license application. The application describes a project that would be located in the Gulf of Mexico, in Main Pass block MP 258, approximately 63 miles south of Mobile Point, Alabama. The Coast Guard and MARAD request public comments on the DEIS. Publication of this notice begins a 45 day comment period and provides information on how to participate in the process.

We are adopting a new airworthiness directive (AD) that supersedes AD 2006-22-08, which applies to all Air Tractor, Inc. (Air Tractor) Models AT-602, AT-802, and AT-802A airplanes. AD 2006-22-08 currently requires you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. Since we issued AD 2006-22-08, the FAA has received reports of two Model AT- 802A airplanes with cracked engine mounts below the initial compliance time in AD 2006-22-08. The FAA has determined that an initial inspection is required when the airplane reaches a total of 1,300 hours time-in-service (TIS) instead of 4,000 hours TIS required by AD 2006- 22-08. Consequently, this AD retains the actions of AD 2006-22-08 while requiring the initial inspection when the airplane reaches a total of 1,300 hours TIS. We are issuing this AD to detect and correct cracks in the engine mount, which could result in failure of the engine mount. Such failure could lead to separation of the engine from the airplane.

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

FMCSA announces that it has received from the National Agricultural Aviation Association (NAAA) an application for an exemption from the commercial driver's license (CDL) requirements. NAAA requests that commercial motor vehicle drivers working with agricultural aircraft operators be exempt from the required knowledge and skills tests and be eligible to receive a restricted CDL. NAAA also requests an exemption to allow these restricted CDL holders to transport fuels used to power agricultural aircraft engines if transported in quantities of 1,000 gallons or less. NAAA believes that relief from the CDL regulations will relieve a current economic hardship and will provide parity in the CDL regulations compared to other, nearly identical farm-related services. NAAA believes that the evidence provided in the exemption request demonstrates that the level of safety achieved under the exemption would be equal to or greater than the level of safety that prevails without the exemption. FMCSA requests public comment on the NAAA application for exemption.

In compliance with the Paperwork Reduction Act of 1995, this notice announces that the Information Collection abstracted below has been forwarded to the Office of Management and Budget (OMB) for review and approval. The nature of the information collection is described as well as its expected burden. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on April 23, 2007. No comments were received.

This notice announces actions taken by the FHWA and other Federal agencies that are final within the meaning of 23 U.S.C. 139(1)(1). These actions relate to a proposed Highway project on State Route 50 between Post Mile L0.9 to 12.8 in Sacramento County, State of California. These actions grant approvals for the project.

The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 186 Automatic Dependent Surveillance- Broadcast (ADS-B).

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-400, 747-400D, 747-400F, 757-200, 767-200, 767-300, and 767-300F series airplanes. This proposed AD would require inspecting to determine the date code of the time delay relay for the cargo fire suppression system, and replacing the relay if necessary. This proposed AD results from a report indicating that failure of a time delay relay on an ELMS (electrical load management system) panel led to testing of other time delay relays at Boeing and at the supplier. Similar relays are used in the cargo fire suppression system. The time delay relay controls when the fire bottles discharge. We are proposing this AD to ensure there is sufficient fire suppressant to control a cargo fire if the airplane is more than the relay delay time from a suitable airport, which could result in an uncontrollable fire in the cargo compartment.
