Airworthiness Directives; CFM International S.A. Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for all CFM International (CFM) S.A. CFM56-7B series turbofan engines. This proposed AD was prompted by a dual engine thrust instability event that resulted in the overspeed and in-flight shutdown (IFSD) of one engine. This proposed AD would require modification of the engine by removing full authority digital engine control (FADEC) software, version 7BV4 or earlier, installed in the electronic engine controls (EECs) on CFM56-7B engines. We are proposing this AD to prevent a thrust instability event, which could lead to overspeed and IFSD of one or more engines, loss of thrust control, damage to the engine, and damage to the airplane.
Airworthiness Directives; Rolls-Royce Corporation Turboprop and Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for certain Rolls-Royce Corporation (RRC) AE 2100 series turboprop engines and AE 3007A and 3007C series turbofan engines. This proposed AD was prompted by reports of pitting in the wheel bores and subsequent RRC analysis that concluded that lower life limits are needed for the affected turbine wheels. This proposed AD would reduce the approved life limits of the affected turbine wheels. This proposed AD would also require an eddy current inspection (ECI) of certain RRC engines with affected turbine wheels. We are proposing this AD to prevent uncontained failure of the turbine wheels, damage to the engine, and damage to the airplane.
Airworthiness Directives; Alpha Aviation Concept Limited Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Alpha Aviation Concept Limited Model R2160 airplanes. 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 paint adherence defects inside the engine air intake box and cohesion defects inside the laminated ducting from the filter to the air intake box. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Rolls-Royce Corporation Turboprop and Turboshaft Engines
We propose to supersede airworthiness directive (AD) 2012-14- 06, which applies to certain Rolls-Royce Corporation (RRC) 250-C20, - C20B, and -C20R/2 turboshaft engines. AD 2012-14-06 currently requires a one-time visual inspection and fluorescent-penetrant inspection (FPI) on certain 3rd-stage and 4th-stage turbine wheels for cracks in the turbine blades. Since we issued AD 2012-14-06, we determined that the one-time inspection required by AD 2012-14-06 should be changed to repetitive inspections and that we should add an inspection after any engine hot start. We also identified additional engine models subject to the unsafe condition. This proposed AD would replace the one-time visual inspection and FPI with repetitive visual inspections and FPIs, and would also require inspection and FPI after any engine hot start. This proposed AD would also add certain engine models to the applicability. We are proposing this AD to prevent failure of 3rd-stage and 4th-stage turbine wheel blades, which could cause engine failure and damage to the aircraft.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for all Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by reports of dislodged engine fan cowl panels. This proposed AD would require installing additional attaching hardware on the left and right fan cowl access panels and the nacelle attaching structures. We are proposing this AD to prevent damage to the fuselage and flight control surfaces from dislodged engine fan cowl panels.

Airworthiness Directives; Airbus Airplanes
We propose to rescind Airworthiness Directive (AD) 2010-08-08, which applies to certain Airbus Model A330-243, -341, -342, and -343 airplanes. AD 2010-08-08 requires deactivating the water scavenge automatic operation and revising the Limitations section of the airplane flight manual (AFM). We also propose to rescind AD 2011-06-04, which applies to certain Model A330-243F airplanes. AD 2011-06-04 requires revising the Limitations section of the AFM. We issued ADs 2010-08-08 and 2011-06-04 to prevent fuel flow restriction, caused by ice, resulting in a possible engine surge or stall condition, and the engine being unable to provide the commanded thrust. Since we issued ADs 2010-08-08 and 2011-06-04, we have determined that the water scavenge system (WSS) operation does not induce any risk of fuel feed system (including the engine) blockage by ice on the pipework or pump inlets. We have also determined that the risk of fuel flow restriction by ice at the fuel oil heat exchanger (FOHE) interface on airplanes equipped with Trent 700 engines is now addressed by a re-designed FOHE, which incorporates enhanced anti-icing and de-icing performance.
Maintenance of and Access to Records Pertaining to Individuals
This rule conforms DOT's regulations on Maintenance of and Access to Records Pertaining to Individuals to the applicable System of Records Notices (SORNs) and current DOT practice. This rule adds the General Investigation Records System to the list of DOT Privacy Act Systems of Records that are exempt from one or more provisions of the Privacy Act. DOT also exempts the Personnel Security Record System from additional provisions of the Privacy Act, as well as correcting the identification number for that System. These exemptions were initially established in 1975; however, a 1980 rulemaking accidentally omitted these exemptions. These changes are effective immediately, though DOT invites public comment.
General Technical, Organizational, and Conforming Amendments to the Federal Motor Carrier Safety Regulations
FMCSA amends its regulations by making technical corrections throughout title 49 of the Code of Federal Regulations (CFR), subtitle B, chapter III. The Agency is making minor changes to correct errors and omissions, ensure conformity with Office of the Federal Register style guidelines, update references, and improve clarity and consistency of certain regulatory provisions. This rule does not make any substantive changes to the affected regulations.
Projects of National and Regional Significance Survey
This notice announces that the Projects of National and Regional Significance (PNRS) survey required under section 1120 of the Moving Ahead for Progress in the 21st Century Act (MAP-21) will re-open on October 2, 2014. The original survey period ran from May 29, 2014, to June 30, 2014. However, in order to develop a more comprehensive catalogue of Projects of National and Regional Significance to assist DOT in planning and investment decisionmaking, DOT will re-open the survey for 45 calendar days, including Federal holidays through November 17, 2014. This will provide interested parties with an additional opportunity to submit projects for consideration and supplement existing submissions. The DOT may not consider responses submitted after November 17, 2014, so as to allow DOT to deliver the MAP-21 mandated report to Congress within a reasonable timeframe.
Harmonization of Airworthiness Standards-Miscellaneous Structures Requirements
This final rule amends certain airworthiness regulations for transport category airplanes, based on recommendations from the FAA- sponsored Aviation Rulemaking Advisory Committee (ARAC). This amendment eliminates regulatory differences between the airworthiness standards of the FAA and the European Aviation Safety Agency (EASA). This final rule does not add new requirements beyond what manufacturers currently meet for EASA certification and does not affect current industry design practices. This final rule revises the structural test requirements necessary when analysis has not been found reliable; clarifies the quality control, inspection, and testing requirements for critical and non-critical castings; adds control system requirements that consider structural deflection and vibration loads; expands the fuel tank structural and system requirements regarding emergency landing conditions and landing gear failure conditions; adds a requirement that engine mount failure due to overload must not cause hazardous fuel spillage; and revises the inertia forces requirements for cargo compartments by removing the exclusion of compartments located below or forward of all occupants in the airplane.
Disadvantaged Business Enterprise: Program Implementation Modifications
The U.S. Department of Transportation (DOT or Department) is amending its disadvantaged business enterprise (DBE) program regulations to improve program implementation in three major areas or categories. First, the rule revises the uniform certification application and reporting forms, creates a uniform personal net worth form, and collects data required by the Moving Ahead for Progress in the 21st Century Act (MAP-21), on the percentage of DBEs in each State. Second, the rule strengthens the certification-related program provisions, which includes adding a new provision authorizing summary suspensions under specified circumstances. Third, the rule modifies several other program provisions concerning such subjects as: Overall goal setting, good faith efforts, transit vehicle manufacturers, and counting for trucking companies. The revision also makes minor corrections to the rule.
