Department of Transportation February 10, 2005 – Federal Register Recent Federal Regulation Documents

This document incorporates corrections to Airworthiness Directive (AD) 2005-01-04, which was published in the Federal Register on January 6, 2005 (70 FR 1169) with regulatory corrections published on January 27, 2005 (70 FR 3871). AD 2005-01-04 applies to certain Raytheon Aircraft Company 90, 99, 100, 200, and 300 series airplanes. This action incorporates the corrections into one document to help eliminate any confusion. We are re-issuing the AD in its entirety.

The National Park Service (NPS) and the Federal Aviation Administration (FAA), as required by the National Parks Air Tour Management Act of 2000, established the National Parks Overflights Advisory Group (NPOAG) in March 2001. The NPOAG was formed to provide continuing advice and counsel with respect to commercial air tour operations over and near national parks. This notice informs the public of two vacancies on the NPOAG (now the NPOAG Aviation Rulemaking Committee) for members representing environmental interests and invites interested persons to apply to fill the vacancies.

This document proposes superseding an existing airworthiness directive (AD) for the specified Eurocopter France (ECF) model helicopters. That AD currently requires replacing certain main or combiner gearboxes with airworthy gearboxes. Further investigation has shown that the main gearbox is not affected, and this action would require replacing a certain combiner gearbox with a modified airworthy gearbox. This proposal is prompted by a report of a freewheel unit slipping resulting in an engine overspeed and shutdown. Also, this proposal is prompted by the conclusion of the investigation, which finds the freewheel slippage is due to the surface treatment applied to certain freewheel rollers in the combiner gearbox. The actions specified by the proposed AD are intended to prevent an engine overspeed, an engine shutdown, and subsequent loss of control of the helicopter.

This document proposes adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A119 helicopters. This proposal would require visually inspecting each main transmission support fitting (fitting) attachment bolt (bolt) for a fracture, a crack, or looseness, and verifying the torque on each fitting bolt. This proposal is prompted by two incidents of fatigue failure of the bolts that secure the transmission rear support fittings to the helicopter. The actions specified by this proposed AD are intended to detect a fracture, a crack, or looseness of a fitting bolt, and prevent fatigue failure of a fitting bolt and subsequent loss of control of the helicopter.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing transport category airplanes listed above. This proposed AD would require repetitive inspections for cracks of the upper surface of the aft lower spar web of the inboard and outboard struts, as applicable; and repetitive inspections for cracks of the upper surface of the intermediate web bay of the aft lower spar. This proposed AD would also require repetitive inspections and torque checks of the bolts common to the aft lower spar chords and the fitting of the rear engine mount bulkhead for missing, loose, or fractured bolts, as applicable; and corrective action, if necessary. This proposed AD is prompted by reports of cracking in the aft lower spar web and reports of missing and fractured bolts. We are proposing this AD to detect and correct cracking of the aft lower spar web, and to prevent missing, loose, or fractured bolts common to the aft lower spar chords and the fitting of the rear engine mount bulkhead, which could result in the loss of the aft lower spar load path and reduced structural capability of the pylon, which may result in the separation of the engine from the airplane.

RSPA is extending until April 28, 2005, the period for interested persons to submit comments on the December 30, 2004 notice of proposed rulemaking In the December 30, 2004 NPRM, we proposed to amend the Hazardous Materials Regulations to prohibit flammable liquids from being transported in unprotected product piping on existing and newly manufactured DOT specification cargo tank motor vehicles. If adopted as proposed, this action will reduce fatalities and injuries that result from accidents involving unprotected product piping. This proposal was developed jointly with the Federal Motor Carrier Safety Administration.

The Maritime Administration (MARAD) has received applications under 46 CFR part 249 from Axis Specialty Limited and Gard Marine and Energy Limited, both Bermuda based underwriters, to write marine hull insurance on Title XI program vessels. In accordance with 46 CFR 249.7(b), interested persons are hereby afforded an opportunity to bring to MARAD's attention any discriminatory laws or practices relating to the placement of marine hull insurance which may exist in the applicant's country of domicile. All comment submissions must include the docket number that appears at the top of this document. Written comments may be submitted to the Docket Clerk, U.S. DOT Dockets, Room PL-401, 400 Seventh Street, SW., Washington, DC 20590. Comments may also be submitted by electronic means via the Internet at https://dmses.dot.gov/submit. All comments received will be available for examination at the above address between 10 a.m. and 5p.m., Monday through Friday, except Federal holidays.

In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), this notice announces that the information Collection Request (ICR) abstracted below has been forwarded to the Office of Management and Budget (OMB) for extension of the currently approved collection. The ICR describes the nature of the information collection and the expected burden. The Federal Register notice with a 60-day comment period soliciting comments on the following collection of information was published on September 10, 2004, page 54840.

This action amends Title 14 Code of Federal Regulations, part 71 (14 CFR part 71) by revising Class E airspace at Nevada, MO. A review of the Class E airspace area extending upward from 700 feet above the surface at Nevada, MO, revealed it does not reflect the current Nevada Municipal Airport airport reference point (ARP) nor the correct location of the Nevada nondirectional radio beacon (NDB) and is not in compliance with established airspace criteria. Extensions to this airspace area are enlarged and modified to conform to FAA Orders. The intended effect of this rule is to provide controlled airspace of appropriate dimensions to protect aircraft departing from and executing Standard Instrument Approach Procedures (SIAPs) to Nevada Municipal Airport.

The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce Deutschland Ltd. & Co KG (RRD) (formerly Rolls- Royce plc) Model Tay 611-8, 620-15, 650-15, and 651-54 turbofan engines, with low pressure (LP) fuel tube, part number (P/N) JR33021A, installed. That AD currently requires initial and repetitive inspections of the LP fuel tubes. This AD requires the same inspections and adds a requirement to replace the fuel tube with a new design tube, as mandatory terminating action to the repetitive inspections. This AD results from the manufacturer introducing a new design fuel tube, which eliminates the unsafe condition. We are issuing this AD to prevent a dual-engine flameout due to fuel exhaustion, which could lead to forced landing and possible damage to the airplane.
