Airworthiness Directives; Rolls-Royce Corporation Turboshaft Engines
Document Number: 2012-16797
Type: Rule
Date: 2012-07-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Corporation (RRC) 250-C20, -C20B, and -C20R/2 turboshaft engines. This AD was prompted by seven cases reported of released turbine blades and shrouds, which led to loss of power and engine in- flight shutdowns (IFSDs). This AD requires a one-time visual inspection and fluorescent penetrant inspection (FPI) on certain 3rd and 4th stage turbine wheels for cracks in the turbine blades. We are issuing this AD to prevent failure of 3rd or 4th stage turbine wheel blades which could cause engine failure and damage to the airplane.

Airworthiness Directives; Airbus Airplanes
Document Number: 2012-15897
Type: Rule
Date: 2012-07-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; all Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model 300 C4-605R Variant F airplanes (collectively called A300-600 series airplanes). This AD was prompted by reports of an inoperative fire shut-off valve (FSOV) as a result of damage due to over-length of the bonding lead. This AD requires a one- time detailed inspection for length of the FSOV bonding leads and for contact or chafing of the wires, and corrective actions, if necessary. We are issuing this AD to detect and correct contact or chafing of wires and bonding leads which, if not detected could be a source of sparks in the wing trailing edge, and could lead to an uncontrolled engine fire.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-15894
Type: Rule
Date: 2012-07-10
Agency: Federal Aviation Administration, Department of Transportation
We are superseding an existing airworthiness directive (AD) for certain The Boeing Company Model 747-100, 747-100B, 747-200B, 747- 200C, 747-200F, 747-400F, 747SR, and 747SP series airplanes, without a stretched upper deck or stretched upper deck modification. That AD currently requires repetitive inspections for cracks of each affected tension tie and of the surrounding structure, and related investigative and corrective actions if necessary. This new AD requires, for certain airplanes, modifying the tension tie structure or tension tie and frame structure at certain stations; and a post-modification inspection of the modified area and post-modification repetitive inspections of the unmodified area, and repair if necessary. Doing the modification would terminate the repetitive inspection requirements in the existing AD. This AD reduces the compliance time and adds inspections for certain airplanes. This AD was prompted by reports that certain airplanes have tension ties that are susceptible to widespread fatigue damage. This AD also results from reports of cracks on the forward and aft tension tie channels at station (STA) 740 and STA 760, and a determination that initial inspection intervals need to be reduced. We are issuing this AD to prevent tension ties from becoming severed or disconnected from the frames, which could lead to rapid in-flight decompression.
Special Conditions: Boeing, Model 737-800; Large Non-Structural Glass in the Passenger Compartment
Document Number: 2012-16720
Type: Rule
Date: 2012-07-09
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Boeing Model 737- 800 airplane. This airplane as modified by Lufthansa Technik will have a novel or unusual design feature associated with the installation of large non-structural glass items in the cabin area of an executive interior occupied by passengers and crew. The installation of these items in a passenger compartment, which can be occupied during taxi, takeoff, and landing, is a novel or unusual design feature with respect to the material used. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. 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 airworthiness standards.

Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-16668
Type: Proposed Rule
Date: 2012-07-09
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposed airworthiness directive (AD) for certain The Boeing Company Model 747-400, -400D, and -400F series airplanes. That NPRM proposed to require repetitive operational tests of the engine fuel suction feed of the fuel system, and other related testing if necessary. That NPRM was prompted by reports of two in-service occurrences on Model 737-400 airplanes of total loss of boost pump pressure of the fuel feed system, followed by loss of fuel system suction feed capability on one engine, and in-flight shutdown of the engine. This action revises that NPRM by proposing to require repetitive operational tests and corrective actions if necessary. We are proposing this supplemental NPRM to detect and correct loss of the engine fuel suction feed capability of the fuel system, which in the event of total loss of the fuel boost pumps could result in dual engine flameout, inability to restart the engines, and consequent forced landing of the airplane. Since these actions impose an additional burden over that proposed in the previous NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Proposed Establishment of Class E Airspace; Reidsville, GA, and Proposed Amendment of Class E Airspace; Vidalia, GA
Document Number: 2012-16447
Type: Proposed Rule
Date: 2012-07-05
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to establish Class E Airspace at Reidsville, GA. Separation of existing Class E airspace surrounding Swinton Smith Field at Reidsville Municipal Airport, Reidsville, GA, from the Class E airspace of Vidalia Regional Airport, Vidalia, GA, has made this action necessary to enhance the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport. This action also would change the names of both airports and update the airport's geographic coordinates.

Proposed Legal Interpretation
Document Number: 2012-16342
Type: Proposed Rule
Date: 2012-07-05
Agency: Federal Aviation Administration, Department of Transportation
On June 1, 2012 at 77 FR 32441, the FAA published a proposed legal interpretation in which the agency considered clarifying prior legal interpretations regarding pilot in command discretion under 14 CFR 121.547(a)(3) and (a)(4). The agency inadvertently assigned an incorrect docket number to the proposed legal interpretation. This document corrects the docket number. Any comments submitted to docket number FAA-2011-0045 regarding the proposed legal interpretation published at 77 FR 32441 will be moved to the correct docket, FAA-2012- 0670.
Airworthiness Standards: Aircraft Engines; Technical Amendment
Document Number: 2012-16290
Type: Rule
Date: 2012-07-05
Agency: Federal Aviation Administration, Department of Transportation
This amendment clarifies aircraft engine vibration test requirements in the airworthiness standards. The clarification is in response to inquiries from applicants requesting FAA engine type certifications and aftermarket certifications, such as supplemental type certificates, parts manufacturing approvals, and repairs. We are revising the regulations to clarify that ``engine surveys'' require an engine test. The change is not substantive in nature, and will not impose any additional burden on any person.
Airworthiness Directives; Pratt & Whitney Canada Turboprop Engines
Document Number: 2012-16257
Type: Rule
Date: 2012-07-05
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Pratt & Whitney Canada (P&WC) PW118, PW118A, PW118B, PW119B, PW119C, PW120, PW120A, PW121, PW121A, PW123, PW123B, PW123C, PW123D, PW123E, PW123AF, PW124B, PW125B, PW126A, PW127, PW127E, PW127F, PW127G, and PW127M turboprop engines. This AD requires initial and repetitive inspections of certain serial numbers (S/Ns) of propeller shafts for cracks and removal from service if found cracked. This AD was prompted by reports of two propeller shafts found cracked at time of inspection during maintenance. We are issuing this AD to detect propeller shaft cracks, which could cause failure of the shaft, propeller release, and loss of control of the airplane.
Removal of the Part 67 Requirement for Individuals Granted the Special Issuance of a Medical Certificate to Carry Their Letter of Authorization While Exercising Pilot Privileges; Confirmation of Effective Date
Document Number: 2012-16317
Type: Rule
Date: 2012-07-03
Agency: Federal Aviation Administration, Department of Transportation
This action confirms the effective date of the direct final rule published on March 22, 2012. The rule removes a regulatory provision under Federal Aviation Administration (FAA) medical certification standards that requires individuals granted the Special Issuance of a Medical Certificate (Authorization) to have their letter of Authorization in their physical possession or readily accessible on the aircraft while exercising pilot privileges.
Airworthiness Directives; Agusta S.p.A. Helicopters
Document Number: 2012-16314
Type: Proposed Rule
Date: 2012-07-03
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A119 and AW119 MKII helicopters. The existing AD currently requires inspecting the pilot and copilot engine rotary variable differential transformer (RVDT) control box assemblies to determine if the control gear locking pin is in its proper position. Since we issued that AD, Agusta has developed a terminating action for this inspection. The proposed actions are intended to prevent failure of an RVDT control box assembly, loss of manual control of the engine throttle, and subsequent loss of control of the helicopter.

Draft Parachute Landing Area Standards
Document Number: 2012-15912
Type: Proposed Rule
Date: 2012-07-03
Agency: Federal Aviation Administration, Department of Transportation
The Federal Aviation Administration (FAA), U.S. Department of Transportation (DOT), invites the United States Parachute Association, skydiving businesses, airport operators, airport consultants, industry representatives and all other interested parties to review and comment on the draft ``Parachute Landing Area Standards'' contained in Change 19 to the Airport Design Advisory Circular (``AC''), AC 150/5300-13. This change establishes new standards and recommendations for parachute landing areas on airports. This action proposes to clarify the FAA policies and standards concerning access to federally obligated airports for parachute landing activities. It also proposes to clarify Grant Assurance No. 22, ``Economic Nondiscrimination,'' which is required of a sponsor as a condition of receiving a grant under the Airport Improvement Program (AIP), to incorporate these standards.
Eighth Meeting: RTCA Special Committee 225, Rechargeable Lithium Battery and Battery Systems-Small and Medium Sizes
Document Number: 2012-16110
Type: Notice

The FAA is issuing this notice to advise the public of the eighth meeting of RTCA Special Committee 225, Rechargeable Lithium Battery and Battery SystemsSmall and Medium Sizes.
Air Traffic Procedures Advisory Committee
Document Number: 2012-16100
Type: Notice
Date: 2012-07-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA is issuing this notice to advise the public of its environmental review of four standard instrument departure procedures at LaGuardia International Airport (LGA). As required by the National Environmental Policy Act, an evaluation has been performed on the four proposed standard instrument departure procedures to determine the level of environmental review warranted. The FAA has elected to ``Categorically Exclude from further environmental review'' the four proposed departure procedures identified as GLDMN FOUR (RNAV) Runway 13, NTHNS TWO (RNAV) Runway 13, HOPEA ONE (RNAV) Runway 22, and JUTES ONE (RNAV) Runway 22.
Airworthiness Directives; the Boeing Company Airplanes
Document Number: 2012-16099
Type: Proposed Rule
Date: 2012-07-02
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposed airworthiness directive (AD) to supersede an existing AD for all The Boeing Company Model 767 airplanes. The existing AD currently requires repetitive inspections to detect discrepancies of the wiring and surrounding Teflon sleeves of the fuel tank boost pumps and override/jettison pumps; replacement of the sleeves with new sleeves, for certain airplanes; and repair or replacement of the wiring and sleeves with new parts, as necessary. The previous NPRM proposed to reduce the initial compliance time and repetitive inspection interval in the existing AD. The previous NPRM was prompted by fleet information indicating that the repetitive inspection interval in the existing AD is too long because excessive chafing of the sleeving continues to occur much earlier than expected between scheduled inspections. This action revises the previous NPRM by proposing a terminating action for the repetitive inspections, to eliminate wire damage. This action also removes certain airplanes from the applicability of the previous NPRM. We are proposing this supplemental NPRM to detect and correct chafing of the fuel pump wire insulation and consequent exposure of the electrical conductor, which could result in electrical arcing between the wires and conduit and consequent fire or explosion of the fuel tank. Since these actions impose an additional burden over that proposed in the previous NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Airworthiness Directives; Airbus Airplanes
Document Number: 2012-16096
Type: Proposed Rule
Date: 2012-07-02
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by reports of the escape slide of the raft inflation system not deploying when activated due to the rotation of the cable guide in a direction which resulted in jamming of the inflation control cable. This proposed AD would require modifying the affected slide rafts. We are proposing this AD to prevent non-deployment of the inflation system of the escape slide raft, which could result in delayed evacuation from the airplane during an emergency, and consequent injury to the passengers.
Combined Drug and Alcohol Testing Programs
Document Number: 2012-16009
Type: Proposed Rule
Date: 2012-07-02
Agency: Federal Aviation Administration, Department of Transportation
This rulemaking would allow air carrier operators and commuter or on-demand operators that also conduct commercial air tour operations to combine the drug and alcohol testing required for each operation into one testing program. The current rule requires those operators to conduct separate testing programs for their air tour operations. This results in an unnecessary duplication of effort. The intended effect of this rulemaking is to decrease operating costs by eliminating the requirement for duplicate programs while maintaining the level of safety intended by the current drug and alcohol testing regulations. This proposal would also clarify existing instructions within the rule, correct an inadvertent typographical error, clarify an existing requirement by rearranging its numerical order, and remove language that describes a practice that has been discontinued.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
Document Number: 2012-15985
Type: Rule
Date: 2012-07-02
Agency: Federal Aviation Administration, Department of Transportation
We are superseding an existing airworthiness directive (AD) for all Rolls-Royce plc (RR) models RB211-Trent 970-84, 970B-84, 972- 84, 972B-84, 977-84, 977B-84, and 980-84 turbofan engines. That AD currently requires inspecting the intermediate-pressure (IP) shaft rigid coupling splines for wear resulting in rearward movement of the IP turbine. This AD requires the same inspections, and new inspections based on possible changes in wear rate. This AD was prompted by RR identifying wear beyond engine manual limits on the abutment faces of the splines. RR also determined that an additional IP shaft rigid coupling configuration requires inspection. We are issuing this AD to detect wear on the abutment faces of the splines, which could result in loss of disc integrity, an uncontained failure of the engine, and damage to the airplane.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (RRD) Turbofan Engines
Document Number: 2012-15961
Type: Rule
Date: 2012-07-02
Agency: Federal Aviation Administration, Department of Transportation
We are rescinding an airworthiness directive (AD) for RRD BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines. The existing AD resulted from the need to reduce the published life limits of high-pressure (HP) turbine stage 1 discs, part numbers (P/Ns) BRH20130 and BRH20131, and HP turbine stage 2 discs, P/Ns BRH19423 and BRH19427. We are rescinding the existing AD because RRD has revised the approved published life limits of these parts to the same or higher limits as originally certified.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-15898
Type: Rule
Date: 2012-07-02
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires inspecting parts or doing a records review to determine if certain trailing edge flap carriages are installed, doing repetitive inspections for corrosion, and flaking or missing thermal coating on suspect carriage spindles, and related investigative and corrective actions, if necessary; this AD also provides optional terminating action for the repetitive inspections. This AD was prompted by reports of corrosion found on carriage that are located on the outboard flaps. We are issuing this AD to detect and correct corrosion of the carriage spindle, which could result in a fracture; fracture of both the inboard and outboard carriage spindles, at the forward ends through the large diameters, on a single flap assembly, could adversely affect the continued safe flight and landing of the airplane.
Airworthiness Directives; Empresa Brasileria de Aeronáutica S.A. (EMBRAER) Airplanes
Document Number: 2012-15752
Type: Rule
Date: 2012-07-02
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Empresa Brasileria de Aeron[aacute]utica S.A. (EMBRAER) Model EMB-505 airplanes. 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 an inadequate amount of drain holes in the primary control surfaces (rudder, elevator, and aileron) and their tab surfaces, which may allow water to accumulate in the control surfaces. This condition could cause unbalanced flight control surfaces and reduced flutter margins, which could result in loss of control of the airplane. We are issuing this AD to require actions to address the unsafe condition on these products.
