Department of Transportation March 17, 2010 – Federal Register Recent Federal Regulation Documents

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: Certain main landing gear components have experienced premature failure during certification testing. Revision has been made to the DHC-8-400 Maintenance Requirements Manual, Airworthiness Limitation Items, to incorporate the revised safe life limits for the main landing gear lock actuator assembly, retraction actuator assembly rod end and piston, and the upper bearing in the main landing gear shock strut assembly. Failure of these components could adversely affect the structural integrity of the main landing gear. The proposed

In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. Chapter 35, as amended), this notice announces that the Information Collection Request (ICR) abstracted below will be forwarded to the Office of Management and Budget (OMB) for renewal and comment. The ICR describes the nature of the information collection and its expected costs and burden. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on January 8, 2010 [Vol. 75, No. 5, Page 1112]. No comments were received.

The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-45 and CF6-50 series turbofan engines with certain low-pressure turbine (LPT) stage 3 disks installed. This AD requires fluorescent penetrant inspection (FPI) of the LPT stage 3 disk under certain conditions and removal of the disk from service before further flight if found cracked. This AD also requires initial and repetitive borescope inspections of the high-pressure turbine (HPT) rotor stage 1 and stage 2 blades for wear and damage, including excessive airfoil material loss. This AD results from three reports of uncontained failures of LPT stage 3 disks and eight reports of cracked LPT stage 3 disks found during shop visit inspections. We are issuing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.

FMCSA proposes to amend its regulations by establishing direct final rulemaking procedures for use on noncontroversial rules. Under these procedures, FMCSA would make regulatory changes that would become effective a specified number of days after the date of publication in the Federal Register, unless FMCSA receives written adverse comment(s) or written notice of intent to submit adverse comment(s), received by the date specified in the direct final rule. These new procedures would expedite the promulgation of routine or noncontroversial rules by reducing the time and resources necessary to develop, review, clear, and publish separate proposed and final rules. FMCSA would not use the direct final rule procedures for complex or controversial issues.

We are adopting a new airworthiness directive (AD) for certain Model 45 airplanes. This AD requires a general visual inspection for cracked and missing ballscrew assembly sleeves of the flap actuator, repetitive non-destructive liquid penetrant inspections of each sleeve or flap actuator for cracks, and replacement or modification of the flap actuator if necessary. This AD results from reports of cracked and missing ballscrew assembly sleeves of the flap actuators. We are issuing this AD to detect and correct cracked and missing sleeves, which could cause loss of the load-carrying ball bearings on both actuators on one flap, resulting in flap asymmetry and loss of control of the airplane.

The FAA hereby provides notice of intent to release certain airport properties, 15.819 acres at the Melbourne International Airport, Melbourne, Florida from the conditions, reservations, and restrictions as contained in a Quitclaim Deed agreement between the FAA and the City of Melbourne, dated August 6, 1947. The release of property will allow the Melbourne Airport Authority to dispose of the property for other than aeronautical purposes. The property is located in the the Southwest \1/4\ of Section 21, Township 27 South, Range 37 East, Brevard County, Florida. The parcel is currently designated as non-aeronautical use. The property will be disposed of for the purpose of municipal use. The fair market value of the property has been determined by appraisal to be $1,061,211. The airport will receive fair market value for the property, which will be subsequently reinvested in another eligible airport improvement project.

This action amends the legal description of two Jet Routes and seven VHF Omnidirectional Range (VOR) Federal Airways in the vicinity of Gage, OK. The FAA is taking this action because the Gage VHF Omnidirectional Range/Tactical Air Navigation (VORTAC), included as part of the route structure for the airways, is being renamed the Mitbee VORTAC for identity clarification.

This amendment adopts a new airworthiness directive (AD) for the specified Sikorsky Aircraft Corporation (Sikorsky) Model S-76C helicopters. This action requires inspecting the emergency flotation system squib connector (flotation system connector) to determine if a metallic foil shunt is installed. This amendment is prompted by a discovery that a metallic foil shunt meant to prevent inadvertent activation of a flotation system during installation was still installed in the left-hand flotation system connector of a Model S-76C helicopter. The actions specified in this AD are intended to determine if a metallic foil shunt is installed in the flotation system, which could prevent the flotation system from deploying and could prevent the helicopter from staying afloat long enough to enable emergency evacuation after a water landing.

We are adopting a new airworthiness directive (AD) for the specified model helicopters. This AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI AD states that the AD is issued following a manufacturing nonconformity found on one batch of the servo-control caps. With a defective servo-control, rotation of the distributor might not be stopped mechanically since only friction of inner seals holds the distributor sleeve in its position. The AD

This action revises Class E airspace at Dillingham, AK, to accommodate amended Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAPs), conventional SIAPs, and an Obstacle Departure Procedure (ODP) at Dillingham Airport. The FAA is taking this action to enhance safety and management of Instrument Flight Rules (IFR) operations at Dillingham Airport.

This action revises Class E airspace at Scammon Bay, AK, to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAPs) at Scammon Bay Airport. The FAA is taking this action to enhance safety and management of Instrument Flight Rules (IFR) operations at Scammon Bay Airport.
