Federal Aviation Administration 2007 – Federal Register Recent Federal Regulation Documents

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:

The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on July 30, 2007 (72 FR 41438). The error resulted in certain compliance times being mislabeled as units of flight cycles instead of flight hours. This AD applies to all Boeing Model 747 airplanes. This AD requires an inspection of the No. 2 and No. 3 windows on the left and right sides of the airplane to determine their part numbers, and related investigative and corrective actions if necessary.

This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2007-18-52 that was sent previously to all known U.S. owners and operators of Boeing Model 737- 600, -700, -700C, -800, -900, and -900ER series airplanes by individual notices. This AD requires repetitive detailed inspections of the slat track downstop assemblies to verify that proper hardware is installed, one-time torquing of the nut and bolt, and corrective actions if necessary. This AD is prompted by reports of parts coming off the main slat track downstop assemblies. We are issuing this AD to detect and correct loose or missing parts from the main slat track downstop assemblies, which could result in a fuel leak and consequent fire.

The FAA is superseding an existing airworthiness directive (AD) for Turbomeca Artouste III B, Artouste III B1, and Artouste III D turboshaft engines. That AD currently requires removing certain fuel pumps from service and installing serviceable fuel pumps. This AD requires the same actions and adds to the applicability, additional fuel pumps by serial number (SN). This AD results from Turbomeca identifying a number of fuel pump SNs that they omitted from the original population. We are issuing this AD to prevent reduced engine fuel flow and subsequent loss of control of the helicopter, or an accident.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from Mandatory Continuing Airworthiness Information (MCAI) provided by the aviation authority of France to identify and correct an unsafe condition on SMA SR305-230 and SR305-230-1 reciprocating engines. The MCAI states the following:

The Federal Aviation Administration (FAA) announces the final policy for Policy for Diesel (Compression Ignition) Engine Certification.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD would require doing repetitive internal eddy current and detailed inspections to detect cracked stringer tie clips; doing applicable corrective and related investigative actions, if necessary; and measuring the fastener spacing and the edge margin; as applicable. As a temporary alternative to doing the actions described previously, this proposed AD would require repetitive external general visual inspections of the skin and lap joints for cracks and evidence of overload resulting from cracked stringer tie clips, and applicable corrective actions if necessary. This proposed AD results from a report of several cracked stringer tie clips. We are proposing this AD to prevent multiple cracked stringer tie clips and damaged skin and frames, which could lead to the skin and frame structure developing cracks and consequent decompression of the airplane.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Boeing Model 767 airplanes. The existing AD currently requires repetitive measurements of the rudder and elevator freeplay, repetitive lubrications of rudder and elevator components, and related investigative/corrective actions if necessary. This proposed AD would instead require revised repetitive measurements of the rudder freeplay and the elevator freeplay for each of the power control actuators (PCAs) that move the rudder and elevator, corrective and related investigative actions if necessary, and repetitive lubrications of the rudder and elevator components. For some airplanes, this proposed AD would also require related concurrent actions. This proposed AD results from reports of freeplay-induced vibration of the rudder and the elevator. The potential for vibration of the control surface should be avoided because the point of transition from vibration to divergent flutter is unknown. We are proposing this AD to prevent excessive vibration of the airframe during flight, which could result in loss of control of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD would require repetitive detailed inspections for cracking of the left side and right side frame and reinforcement angles at fuselage station (FS) 640 between stringer 9 and stringer 12, and corrective actions if necessary. This proposed AD results from reports that cracks have been discovered on the frame and reinforcement angles at FS 640. We are proposing this AD to detect and correct cracking of the frame, which could lead to failure of the fuselage structure and possible loss of the airplane.

This rule amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of changes in the National Airspace System, such as the commissioning of new navigational facilities, adding of 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. 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 revising an earlier NPRM for an airworthiness directive (AD) that applies to all Airbus Model A300 airplanes; and all Airbus Model A300 B4-601, A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R, A300 F4-622R, and A300 C4-605R Variant F airplanes. The original NPRM would have required inspecting to determine the part number of the sliding rods of the main landing gear (MLG) retraction actuators. For MLG retraction actuators equipped with sliding rods having certain part numbers, the original NPRM would also have required inspecting for discrepancies, including but not limited to cracking, of the sliding rod; and performing corrective actions if necessary. The original NPRM resulted from a report of a failure of a sliding rod of the MLG retraction actuator before the actuator reached the life limit established by the manufacturer. This action revises the original NPRM by proposing to require the return of affected sliding rods to the manufacturer. We are proposing this supplemental NPRM to prevent failure of the sliding rod of the MLG retraction actuator, which could result in reduced structural integrity of the MLG.

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 adopt a new airworthiness directive (AD) for GE CF6-80C2 series and CF6-80E1 series turbofan engines. This proposed AD would require installing doubler pads (deflectors) on stage 5 of certain LPT cases, or replacing those LPT cases with LPT cases that have the deflectors already installed. This proposed AD results from four events of hardware fragments, which liberated into the flowpaths and wore through LPT cases on CF6-80C2 and -80E1 series engines. We are proposing this AD to prevent an uncontained release of engine debris and loss of the structural integrity of the mount system that supports the engine. Loss of the mount system structural integrity could result in the engine separating from the airplane.

This action removes an erroneous reference to a section that appears in the applicability section of operating requirements for commuter and on-demand operations. The intent of this action is to ensure that the regulations are clear and accurate.

We are superseding an existing airworthiness directive (AD) by adopting a new AD for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) provided by the aviation authority of France to identify and correct an unsafe condition on Turbomeca Arriel 2B1 turboshaft engines. The MCAI states the following:

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

This document makes a correction to Airworthiness Directive (AD) 2007-17-03, which was published in the Federal Register on August 21, 2007 (72 FR 46541), and applies to certain Pacific Aerospace Corporation Ltd Model 750XL airplanes. AD 2007-17-03 requires inspecting the inboard end of the rear spar for security of the blind rivets, inspecting the radii of the rear spar upper and lower flanges for cracking, inspecting the aft flange of the inboard rib for cracking, replacing the rear spar if cracks are found in any of the inspections, and replacing rear spar blind rivets with bolts or rivets. The paragraph following the section heading Materials Incorporated by Reference does not have a paragraph designator. This document corrects that paragraph by inserting the paragraph designator ``(i)'' preceding the paragraph text.

We are adopting a new airworthiness directive (AD) for the products listed above.

The FAA announces on October 11, 2007, deadline for submitting requests for international Arrival Authorizations at Chicago O'Hare International Airport (ORD) for allocation under 14 CFR 93.29. The deadline coincides with the submission deadline established by the International Air Transport Association (IATA) for the Summer 2008 Schedules Conference. The U.S. summary scheduling season is from March 9, 2008 through November 1, 2008, in recognition of the U.S. daylight saving time dates. The FAA is aware that the IATA summer 2008 season is March 30, 2008 through October 25, 2008. The FAA will accept schedule changes that coincide with the IATA scheduling season, rather than U.S. daylight saving dates, in order to ease the administrative burdens on carriers conducting international operations and in order to ensure that FAA has the most accurate schedule information. Schedules for the beginning or end of a U.S. scheduling season may be reviewed at the winter or summer schedules conference, as appropriate. The FAA limits arrivals at ORD from 7 a.m. to 9 p.m., Central Time, Monday through Friday, and 12 p.m. to 9 p.m., on Sunday, based primarily on runway capacity limits. The FAA's restrictions at ORD are the equivalent of a Level 3 Full Coordinated Airport as used in the IATA Worldwide Scheduling Guidelines. Separate schedule facilitation is done at the airport level for international passenger flights operating at Terminal 5. Carriers also should file Terminal 5 schedules, if appropriate, to the address listed in the IATA Worldwide Scheduling Guidelines, Annex 3.

The Federal Aviation Administration (FAA) announces that it is reviewing a proposed Noise Compatibility Program that was submitted for Hartsfield-Jackson Atlanta International Airport under the provisions of 49 U.S.C. 47504 et. seq (the Aviation Safety and Noise Abatement Act hereinafter referred to as ``the Act'') and 14 CFR part 150 by the City of Atlanta, Georgia. This program was submitted subsequent to a determination by FAA that the associated Noise Exposure Maps submitted under 14 CFR part 150 for Hartsfield-Jackson Atlanta International Airport were in compliance with applicable requirements effective April 10, 2007, and was published in the Federal Register on April 23, 2007. The proposed Noise Compatibility Program will be approved or disapproved on or before March 4, 2008.

This notice announces the availability of and requests comments on a proposed Advisory Circular (AC): AC No. 135-42, Extended Operations (ETOPS) and Operations in the North Polar Area. Also in this Federal Register, the FAA publishes draft AC No. 120-42B, Extended Operations (ETOPS) and Polar Operations, for public comment.
