Federal Aviation Administration April 2010 – Federal Register Recent Federal Regulation Documents

In a final rule published in the Federal Register on November 9, 1993, an error was made in the airspace description for Restricted Area R-2510A, El Centro, CA. Specifically, the action inadvertently omitted the reference to nautical miles in the boundaries section of the description. This action corrects that error.

This action proposes to revoke Class D and E airspace at Big Delta, AK. This airspace duplicates the controlled airspace for Delta Junction, Alaska, which serves Allen Army Airfield. The duplication makes this action necessary to eliminate possible confusion, and enhance safety and management of Instrument Flight Rules (IFR) operations.

On March 7, 2008, the FAA published a final rule titled ``Revisions to Cockpit Voice Recorder and Digital Flight Data Recorder Regulations.'' The rule required certain upgrades of cockpit voice recorder and digital flight data recorder equipment on certain aircraft beginning April 7, 2010. That compliance date is being changed for certain requirements on certain aircraft.

This notice announces two fact-finding informal airspace meetings to solicit information from airspace users and others, concerning a proposal to establish Class C airspace at Long Beach, CA, and revise the Santa Ana (John Wayne) Class C airspace area, CA. The purpose of these meetings is to provide interested parties an opportunity to present views, recommendations, and comments on the proposal. All comments received during these meetings will be considered prior to any issuance of a notice of proposed rulemaking.

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: Service has shown that the small outlet of the blow-by oil separators, part number 02-7250-18100R1; 02-7250-18100R2; 02-7250- 18100R3; 02-7250-18100R4; 02-7250-18300R1; 02-7250-18300R2; 02-7250- 18300R3; 02-7250-18300R4; or 02-7250-18300R5, may cause a blow-by gas pressure increase inside the crankcase of the engine in excess of the oil seal design pressure limits. Leaking engine oil may adversely affect the gearbox clutch or the engine lubrication system. This condition, if not corrected, could lead to in-flight cases of engine power loss or ultimately, shutdown. We are proposing this AD to prevent loss of engine power or uncommanded engine shutdown during flight due to excessive crankcase blow-by gas pressure.

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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: Three cases of in-flight loss of cabin pressurization have been reported, resulting from failure of a bulkhead check valve in combination with failure of an air supply duct. In addition to mandating inspection, rework and/or replacement of the air supply ducts, Airworthiness Directive (AD) CF-2003-05 (subsequently revised to CF-2003-05R1) [which corresponds to FAA AD 2004-22-08] mandated the incorporation of a 4000 flight-hour repetitive inspection task for bulkhead check valves, Part Numbers (P/N) 92E20-3 and 92E20-4, into the approved maintenance schedule. However, this repetitive inspection task has since been superseded by a 3000 flight-hour periodic discard task for these bulkhead check valves. This directive mandates revision of the approved maintenance schedule to incorporate the discard task for bulkhead check valves, P/N 92E20-3 and 92E20-4, and supersedes the instructions in Corrective Actions, Part A, of AD CF-2003-05R1, dated 7 February 2006. The proposed AD would require

The FAA is issuing this notice to advise the public of a meeting of EUROCAE WG-72: RTCA Special Committee 216: Aeronautical Systems Security (Joint Meeting).

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: Surface defects were visually detected on the rudder of one A319 and one A321 in-service aeroplane. Investigation has determined that the defects reported on both rudders corresponded to areas that had been reworked in production. The investigation confirmed that the defects were a result of de-bonding between the skin and honeycomb core. An extended de-bonding, if not detected and corrected, may degrade the structural integrity of the rudder. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the aeroplane.

The MCAI describes the unsafe condition as: Surface defects were visually detected on the rudder of one Airbus A319 and one A321 in-service aeroplane. Investigation has determined that the defects reported on both rudders corresponded to areas that had been reworked in production. The investigation confirmed that the defects were the result of de-bonding between the skin and honeycomb core. Such reworks were also performed on some rudders fitted on A310 and A300-600 aeroplanes. An extended de-bonding, if not detected and corrected, may degrade the structural integrity of the rudder. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the aeroplane.

The Federal Aviation Administration is requesting public comment on the release of land at the Cincinnati/Northern Kentucky International Airport in the city of Hebron, Kentucky. This property, approximately 75.88 acres of fee simple release, and approximately 28.48 acres of requested easement, will change to a non-aeronautical use. This action is taken under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21).

Pursuant to section 10(a)(2) of the Federal Advisory Committee Act (Pub. L. 92-463, 5 U.S.C. App. 2), notice is hereby given of the meetings of the Commercial Space Transportation Advisory Committee (COMSTAC). The meetings will take place on Tuesday and Wednesday, May 18 and 19, 2010, starting at 8 a.m. at the National Housing Center, 1201 15th Street NW., Washington, DC 20005.

The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce plc RB211-Trent 700 series turbofan engines. That AD currently requires initial and repetitive borescope inspections of the high-pressure-and-intermediate pressure (HP-IP) turbine internal and external oil vent tubes for coking and carbon buildup, and cleaning or replacing the vent tubes if necessary. This AD requires the same actions, but adds additional inspections of the vent flow restrictor. This AD results from further analysis that the cleaning of the vent tubes required by AD 2007-02-05 could lead to loosened carbon fragments, causing a blockage downstream in the vent flow restrictor. We are issuing this AD to prevent internal oil fires due to coking and carbon buildup that could cause uncontained engine failure and damage to the airplane.

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Model 747-200C and -200F series airplanes. That AD currently requires repetitive inspections to find fatigue cracking in the floor panel attachment fastener holes of the upper chord of certain upper deck floor beams in Section 41 (i.e., body station 520 and forward), and repair if necessary. The existing AD also provides optional modifications, which extend the threshold for initiating certain repetitive inspections. This new AD requires additional repetitive inspections to find fatigue cracking in the floor panel attachment fastener holes of the upper chord of certain other upper deck floor beams in Section 41 and Section 42 (i.e., aft of body station 520); repetitive inspections to find fatigue cracking in the permanent fastener holes of the upper chord of certain upper deck floor beams in Section 41; and related investigative and corrective actions. This new AD also provides a new optional modification, which terminates certain repetitive inspections. This AD results from new reports of cracking in the upper chord of the upper deck floor beams in Sections 41 and 42, and new analysis that shows the permanent fastener holes of the upper chord of certain upper deck floor beams in Section 41 are also susceptible to fatigue cracking. We are issuing this AD to detect and correct cracking in the upper chord of the upper deck floor beams. Such cracking could extend and sever the floor beams, which could result in rapid decompression and loss of controllability of the airplane.

This supplemental NPRM revises an earlier proposed airworthiness directive (AD), for certain CFM International, S.A. models CFM56-3 and -3B turbofan engines. That proposed AD would have required initial and repetitive inspections for damage to the fan blades. That proposed AD resulted from a report of a failed fan blade with severe out-of-limit wear on the underside of the blade platform where it contacts the damper. This supplemental NPRM revises the proposed AD to reduce the initial inspection compliance threshold, to correct the engine model designations affected, and to clarify some of the inspection wording in the compliance section. This supplemental NPRM results from a report of a failed fan blade with severe out-of- limit wear on the underside of the blade platform where it contacts the damper. We are proposing this supplemental NPRM to prevent failure of multiple fan blades, which could result in an uncontained failure of the engine and damage to the airplane.

In accordance with National Environmental Policy Act regulations of 1969, as amended (NEPA) (42 U.S.C. 4321 et seq.), Council on Environmental Quality NEPA implementing regulations (40 CFR parts 1500-1508), and FAA Order 1050.1E, Change 1, the FAA is announcing the availability of and requesting comments on the Draft Supplemental Environmental Assessment (SEA) to the September 2008 Environmental Assessment for Space Florida Launch Site Operator License. The Draft SEA was prepared in response to an application for a Launch Site Operator License from Space Florida. Under the Proposed Action, the FAA would issue a Launch Site Operator License to Space Florida to operate a commercial space launch site at Launch Complex 36 (LC-36) and LC-46 at Cape Canaveral Air Force Station (CCAFS) in Brevard County, Florida. The license would allow Space Florida to support vertical launches of both solid and liquid propellant launch vehicles from LC-36 and LC-46. LC-46 is the easternmost launch complex at CCAFS, located at the tip of Cape Canaveral, and LC-36 is located in
