Federal Aviation Administration September 2007 – 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:

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 various repetitive inspections to detect cracks along the chemically milled steps of the fuselage skin or missing or loose fasteners in the area of the preventative modification or repairs, replacement of the time-limited repair with the permanent repair if applicable, and applicable corrective actions if necessary, which would end certain repetitive inspections. This proposed AD results from a fatigue test that revealed numerous cracks in the upper skin panel at the chemically milled step above the lap joint. We are proposing this AD to detect and correct such fatigue-related cracks, which could result in the crack tips continuing to turn and grow to the point where the skin bay flaps open, causing decompression of the airplane.

The FAA proposes to adopt a new airworthiness directive (AD) for McCauley Propeller Systems model 4HFR34C653/L106FA propellers. This proposed AD would require a onetime fluorescent penetrant inspection (FPI) and eddy current inspection (ECI) of the propeller hub for cracks. This proposed AD results from reports of 3 hubs found cracked during propeller overhaul. We are proposing this AD to prevent failure of the propeller hub, which could cause blade separation, damage to the airplane, and loss of control of the airplane.

The FAA is requesting public comment on the City of Manchester, New Hampshire's request to change a portion (.42 acres) of Airport property from aeronautical use to non-aeronautical use. The property is located on South Willow Street, Manchester, New Hampshire and is a portion of map 854, Lot 5 and Map 854, Lot 1B. Upon disposition the property will be used for the realignment of South Willow Street for Runway Safety Area Improvements at Manchester Airport, Manchester, New Hampshire. The property was acquired under AIP Project Nos. 3-33-0011- 31 and 3-33-0011-67. The disposition of proceeds from the disposal of airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999.

This notice requests comments on proposed airworthiness standards for acceptance of the BA609 Tiltrotor under 14 CFR 21.17(b), designation of applicable regulations for special classes of aircraft for which airworthiness standards have not been issued.

Pursuant to Section 176 (c) of the Clean Air Act Amendments of 1990, the FAA announces the availability of the Final General Conformity Determination for Proposed Operations of Lynx Aviation, Inc. (Lynx), at Denver International Airport (DEN). FAA has determined that emissions from Lynx's operations at DEN conform to the applicable Colorado State Implementation Plans (SIPs). In accordance with the requirements of 40 CFR Sec. 93.156(b), FAA made the Draft Air Quality General Conformity Determination (Draft GCD) for Proposed Operations of Lynx Aviation, Inc., at Denver International Airport, Denver, CO available for public review beginning on July 20, 2007. FAA published notice of the draft determination in the ``Rocky Mountain News,'' Denver, Colorado on July 20 and 21, 2007 and DEN made copies of the draft determination available at the airport. FAA published the Notice of Availability and Public Comment Period for the Draft General Conformity Determination in the Federal Register on July 20, 2007 (72 FR 39877). FAA received one comment during the public comment period, which ended on August 20, 2007. The commenter stated that jet aviation activity results in excessive pollution and that there should be less aviation activity in general in the United States. The commenter did not provide comments specific to the Draft General Conformity Determination; therefore, a response to the comment is not necessary. Consequently, the Final General Conformity Determination consists of the Draft General Conformity Determination, with two typographical corrections. 1. Page 1, first sentence in the first paragraph under Introduction was revised to read: ``Lynx Aviation, Inc. (Lynx Aviation) has announced its interest in initiating scheduled service at Denver International Airport (DEN), now commencing in October 2007.'' 2. Page 3, first sentence in the second paragraph under Aircraft and Supportng Equipment Emissions was revised to read: ``Under the Proposed Action alternative, Lynx Aviation intends to introduce service at DEN on October 1, 2007.''

The FAA issues these special conditions for the Boeing Model 787-8 airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These novel or unusual design features are associated with carbon fiber reinforced plastic used in the construction of the fuselage. For these design features, the applicable airworthiness regulations do not contain adequate or appropriate safety standards for impact response characteristics to ensure survivable crashworthiness. 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 standards. We will issue additional special conditions for other novel or unusual design features of the Boeing Model 787-8 airplanes.

This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These novel or unusual design features include wing fuel tanks constructed of carbon fiber composite materials. For these design features, the applicable airworthiness regulations do not contain adequate or appropriate safety standards. 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 standards. Additional special conditions will be issued for other novel or unusual design features of the Boeing Model 787-8 airplanes.

The FAA is adopting a new airworthiness directive (AD) for all Viking Air Limited Model DHC-7 airplanes. This AD requires 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 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 issuing 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 is issuing this notice to advise the public of a meeting of the RTCA Program Management Committee.

Under this notice, the FAA announces that New York's John F. Kennedy International Airport (JFK) and Newark Liberty International Airport (EWR) have been designated Level 2 Schedules Facilitated Airports for the summer 2008 scheduling season in accordance with the International Air Transport Association (IATA) Worldwide Scheduling Guidelines. Accordingly, the FAA announces an October 11, 2007, deadline for submitting schedule information for all planned flights at JFK and EWR between the hours of 6 a.m. and 11 p.m., local time or 1000 and 0300 UTC. The FAA deadline coincides with the submission deadline established by IATA for the Summer 2008 Schedules Conference. The U.S. summer scheduling season is from March 9, 2008, through November 1, 2008, in recognition of the U.S. daylight saving time dates. The FAA understands the IATA summer 2008 season is March 30, 2008, through October 25, 2008. The FAA will accept schedules 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. The Level 2 designations for JFK and EWR are necessary because of increased levels of air traffic operations, congestion and delay at the airports and a tangible decrease in operational performance (performance data for each airport is provided below). The FAA is implementing a number of initiatives for JFK and EWR to improve air traffic control (ATC) efficiency and reduce delays at those and other airports. For instance, ATC has increased use of a second departure runway at JFK when conditions permit. Other measures for both airports will improve routing options during periods of adverse weather conditions. And, over the next several years, the FAA will redesign airspace in the New York/New Jersey/Philadelphia areas in order to improve efficiency and reduce delays. These near term measures, however, are not sufficient to meet the current peak hour operational demands at these airports.

This notice announces a public meeting of the FAA's Aviation Rulemaking Advisory Committee (ARAC) to discuss transport airplane and engine (TAE) issues.

We are adopting a new airworthiness directive (AD) for the products listed above that would supersede existing ADs. This AD results from mandatory continuing airworthiness information (MCAI) issued by the 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.
