Department of Transportation April 2010 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede an existing airworthiness directive (AD) for certain serial numbers (S/Ns) of Bombardier-Rotax GmbH type 912 F and 914 F series reciprocating engines. That AD currently requires initial and repetitive visual inspections of the engine crankcase for cracks. This proposed AD would require those same inspections, would add the 912 S series to the affected population, add a test procedure to determine the engine suitability for a special flight permit, and would change applicability from engine S/N to crankcase S/N. This proposed AD results from an increase in the affected crankcase population. We are proposing this AD to prevent oil loss caused by cracks in the engine crankcase, which could lead to in- flight failure of the engine and forced landing.

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 amend Class E airspace at Cherokee, IA. Decommissioning of the Pilot Rock non-directional beacon (NDB) at Cherokee County Regional Airport has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport.

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.

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

This notice announces a limited program to forgo enforcement action for persons who disclose before September 30, 2010, previous falsification on applications for airman medical certification regarding the use of antidepressant medication, the underlying condition for which the antidepressant was prescribed, and visits to health professionals in connection with the antidepressant use or underlying condition.

The FAA is issuing this notice to advise the public of a meeting of Joint RTCA Special Committee 213: EUROCAE WG-79: Enhanced Flight Vision Systems/Synthetic Vision Systems (EFVS/SVS).

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.

PHMSA is considering amendments to the Hazardous Materials Regulations (HMR) as they apply to the transportation of combustible liquids. Specifically, we are considering whether to harmonize the domestic regulations applicable to the transportation of combustible liquids with international transportation standards. In addition, we are examining ways to revise, clarify, or relax certain regulatory requirements to facilitate the transportation of these materials while maintaining an adequate level of safety. The intent of this ANPRM is to invite public comments on how to accomplish these goals, provide an opportunity for comment on amendments PHMSA is considering, and present a forum for the public to offer additional recommendations for the safe transportation of combustible liquids.

This policy statement is intended to serve as notice that the Federal Aviation Administration (FAA) will consider for a special- issuance medical certificate applicants for first-, second-, and third- class airman medical certification who are being treated for depression with one of four antidepressant medications. The FAA will evaluate affected applicants on a case-by-case basis and will issue certificates based on a medical finding that an individual's use of such medication will not endanger public safety.

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

In accordance with the Paperwork Reduction Act of 1995 and its implementing regulations, the Federal Railroad Administration (FRA) hereby announces that it is seeking renewal of the following currently approved information collection activities. Before submitting these information collection requirements for clearance by the Office of Management and Budget (OMB), FRA is soliciting public comment on specific aspects of the activities identified below.

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.

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 Board is instituting a proceeding to determine the railroad industry's cost of capital for 2009. The decision solicits comments on the following narrow issues: (1) The railroads' 2009 current cost of debt capital; (2) the railroads' 2009 current cost of preferred equity capital (if any); (3) the railroads' 2009 cost of common equity capital; (4) how the change in BNSF Railway Company's (BNSF's) share prices from November 2009 through December 2009, following the announcement of BNSF's acquisition by Berkshire Hathaway Inc., should be considered in calculating the 2009 cost of common equity capital; and (5) the 2009 capital structure mix of the railroad industry on a market value basis. Comments should focus on the various cost of capital components listed above using the same methodology followed in Railroad Cost of Capital2008, Ex Parte No. 558 (Sub-No. 12) (STB served Sept. 25, 2009).

The FAA assigned the Aviation Rulemaking Advisory Committee (ARAC) a new task to identify and develop recommendations on additional requirements for low speed alerting in new transport category airplanes. This task is the first phase of an overall effort to examine new standards, as well as possible retrofit standards. This notice is to inform the public of this ARAC activity.

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 review and comment. The ICR describes the nature of the information collection and the expected burden. The Federal Register notice with a 60-day comment period was published on June 22, 2009. This is a request for a new collection.

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.
