Federal Aviation Administration July 2013 – Federal Register Recent Federal Regulation Documents

This action proposes special conditions for the Eclipse EA500 airplane. This airplane as modified by Innovative Solutions and Support (IS&S) will have a novel or unusual design feature(s) associated with the autothrottle system (ATS). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed 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.

We propose to adopt a new airworthiness directive (AD) for certain Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by a design review, which revealed that under certain failure conditions of the maximum level (Max Level) sensor wiring, a short circuit may develop that causes a hot spot on the wiring conduit, or puncturing of the wiring conduit wall in the center wing fuel tank. This proposed AD would require installing fuses in the Max Level sensor wiring; and revising the airplane maintenance program by incorporating critical design configuration control limitations. We are proposing this AD to prevent an ignition source in the center wing fuel tank vapor space, which could result in a fuel tank explosion and consequent loss of the airplane.

We propose to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes. This proposed AD was prompted by a report of a cracked pick- up bracket of the forward outboard pylon of the number 1 engine due to stress corrosion. This proposed AD would require repetitive inspections and, depending on findings, repair of the pylon pick-up brackets. We are proposing this AD to detect and correct cracking of the pick-up bracket, which could result in the engine pylon separating from the wing, with consequent damage to the airplane and reduced controllability.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval for a new information collection. The collection involves an assessment of the number of ferry flights typically conducted by on-demand air carriers and the costs associated with those flights. The information to be collected will be used to conduct a benefit cost analysis in connection with rulemaking as required by Congress.

We are revising an earlier proposed airworthiness directive (AD) for all The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. That supplemental notice of proposed rulemaking (SNPRM) proposed to require revising the maintenance program to incorporate a revision to the Airworthiness Limitations Section of the maintenance planning data (MPD) document. That SNPRM 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 SNPRM by adding Model 777F series airplanes to the applicability. We are proposing this AD to detect and correct failure of the engine fuel suction feed 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 this action imposes an additional burden over that proposed in the previous SNPRM, we are reopening the comment period to allow the public the chance to comment on this proposed change.

This action amends Class E airspace at Gustavus Airport, Gustavus, AK. Decommissioning of the Gustavus Nondirectional Radio Beacon (NDB) has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also adjusts the geographic coordinates of the airport.

We are adopting a new airworthiness directive (AD) for certain CFM International, S. A. (CFM) model CFM56-5 and CFM56-5B series turbofan engines. This AD was prompted by corrosion of the delta-P valve in the hydro-mechanical unit (HMU) fuel control caused by exposure to type TS-1 fuel. This AD requires cleaning, inspection, and repair of affected HMUs. We are issuing this AD to prevent seizure of the HMU, leading to failure of one or more engines and damage to the airplane.

This action proposes to establish Class E airspace at the Rome VHF Omni-Directional Radio Range/ Distance Measuring Equipment (VOR/DME) navigation aid, Rome, OR, to facilitate vectoring of Instrument Flight Rules (IFR) aircraft under control of Salt Lake City, Oakland and Seattle Air Route Traffic Control Centers (ARTCCs). The FAA is proposing this action to enhance the safety and management of aircraft operations within the National Airspace System.

This action proposes to amend Class E airspace at St. George Municipal Airport, St. George, UT, by removing the operating hours established by a Notice to Airmen (NOTAM) due to the airport changing from a part time to a full time facility. The FAA is proposing this action to enhance the safety and management of aircraft operations at St. George Municipal Airport, St. George, UT.

Under the provisions of Title 49, U.S.C. 47153(c), notice is being given that the FAA is considering a request from the Huntsville- Madison County Airport Authority to waive the requirement that a 4.58- acre parcel of surplus property, located at the Huntsville International Airport, be used for aeronautical purposes.

This notice contains a summary of a petition seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

The FAA is correcting a final rule published on January 18, 2013 (78 FR 4038). In that rule, the FAA established airworthiness standards for airplane propellers. That action required a safety analysis to identify a propeller critical part. Manufacturers would identify propeller critical parts, and establish engineering, manufacturing, and maintenance processes for propeller critical parts. An unintentional error was introduced in Sec. 35.15 when we revised paragraph (d). We did not intend to revise paragraph (d). This correction will add paragraph (d) to the end of paragraph (c), and restore the former paragraph (d).

We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) GE90-110B1 and -115B turbofan engines. This proposed AD was prompted by multiple events of a leaking variable bypass valve (VBV) actuator fuel supply tube. This proposed AD would require replacement of this VBV actuator fuel supply tube with a part eligible for installation. We are proposing this AD to prevent failure of the affected fuel supply tube, fuel leakage, engine fire, and damage to the airplane.

This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.

We are adopting a new airworthiness directive (AD) for all Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440), CL- 600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD requires revising the airplane flight manual (AFM) by incorporating an emergency procedure for uncommanded yaw motion. This AD was prompted by reports of airplanes experiencing uncommanded rudder movements while in flight. We are issuing this AD to advise the flightcrew of procedures to address a possible failure of the voltage regulator inside the yaw damper actuator that could lead to uncommanded yaw movement and consequent loss of the ability to control the airplane.

We propose to adopt a new airworthiness directive (AD) for all DASSAULT AVIATION Model FAN JET FALCON; Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This proposed AD was prompted by reports of defective fire extinguisher bottle cartridges. This proposed AD would require checking manufacturing references of pyrotechnical cartridges for batch number and date, repetitive checking of cartridges for electrical continuity, and replacing defective pyrotechnical cartridges if necessary. We are proposing this AD to detect and correct defective fire bottle cartridges, which could affect the capability to extinguish a fire in an engine, auxiliary power unit, or rear compartment, which could result in damage to the airplane and injury to the occupants.

We are adopting a new airworthiness directive (AD) for Eurocopter Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, and AS350D1 helicopters with a single hydraulic system and a certain hydraulic pump drive installed. This AD requires inspecting the hydraulic pump drive pulley bearing (pulley bearing) for leaks, rust, overheating, and condition. This AD is prompted by six reports of hydraulic pump drive belt failure caused by seizure of the pulley bearing. These actions are intended to prevent hydraulic pump drive belt failure, loss of hydraulic servo assistance, and subsequent loss of control of the helicopter.

We propose to adopt a new airworthiness directive (AD) for certain Eurocopter Deutschland GmbH (Eurocopter) Model EC135P2+ and EC135T2+ helicopters. This proposed AD would require inspecting the mechanical air conditioning system compressor bearing block upper bearing (upper bearing) for corrosion, leaking grease, condensation, or water. This proposed AD is prompted by metallic debris from an upper bearing found in the air inlet areas of both engines in a Model EC135P2+ helicopter. The proposed actions are intended to prevent metallic debris from damaging the engine, causing loss of engine power, and subsequent loss of helicopter control.

We propose to adopt a new airworthiness directive (AD) for Sikorsky Model S-70, S-70A, and S-70C helicopters. This proposed AD would establish a new life limit based on a prorated formula for certain identified components (parts) installed on Model S-70, S-70A, and S-70C helicopters after being previously installed on certain military model helicopters. This proposed AD is prompted by the discovery that certain parts have been interchanged between military helicopter models with different life limits and the possibility that these same parts can be interchanged with civilian models with different life limits. The proposed actions are intended to establish a pro-rated in service life limit for each identified part to prevent fatigue failure of a part and subsequent loss of control of the helicopter.

We are revising an earlier proposed airworthiness directive (AD) for the Sikorsky Model S-70, S-70A, S-70C, S-70C (M), and S-70C (M1) helicopters with General Electric (GE) T700-GE-401C or T700-GE- 701C engines installed, which proposed establishing new fatigue life limits for certain GE engine gas generator turbine (GGT) rotor parts. The proposed AD was prompted by a reevaluation of the method for determining the life limit for certain GE engine gas generator turbine (GGT) rotor parts and the determination that these life limits need to be based on low cycle fatigue (LCF) events instead of hours time-in- service. This action would retain the previously proposed requirements but correct the life limit formula for a certain GGT rotor part. The proposed actions are intended to prevent fatigue failure of a GGT rotor part, engine failure, and subsequent loss of control of the helicopter.

We propose to adopt a new airworthiness directive (AD) for AgustaWestland Model A109S, AW109SP, A119, and AW119 MKII helicopters to require removing certain rod end assemblies from service. This proposed AD is prompted by reports of fractures on the rod end assemblies that could damage the main rotor assembly and lead to loss of control of the helicopter.

The FAA is issuing this notice to advise the public of the Sixty-Second meeting of the RTCA Special Committee 135, Environmental Conditions and Test Procedures for Airborne Equipment.

The FAA is issuing this notice to advise the public of the twenty-third meeting of the RTCA Special Committee 224, Airport Security Access Control Systems.

The FAA is withdrawing a notice of proposed rulemaking (NPRM). The NPRM proposed a new airworthiness directive (AD) that had applied to certain Hamilton Sundstrand Corporation 14SF-7, 14SF-15, and 14SF-23 series propellers. The NPRM had applied to those propellers using certain Hamilton Sundstrand Corporation auxiliary pumps and motors (auxiliary feathering pumps). The proposed action would have required removal of certain serial numbers (S/Ns) of auxiliary feathering pumps from service. Since we issued the NPRM, we attended a meeting sponsored by Hamilton Sundstrand Corporation, which provided additional information regarding the unsafe condition. The information included results from bond strength tests that predicts a significantly lower fleet risk than the prior qualitative analysis. Accordingly, we withdraw the proposed rule.
