Federal Aviation Administration 2008 – Federal Register Recent Federal Regulation Documents

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:

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all EMBRAER Model ERJ 170-100 LR, -100 SE, -100 STD, and -100 SU airplanes; and Model ERJ 190-100 IGW, -100 LR, and -100 STD airplanes. The existing AD currently requires revising the Limitations section of the airplane flight manual (AFM) to prohibit the flightcrew from moving the throttle into the forward thrust range immediately after applying the thrust reverser. This proposed AD would add additional airplanes to the applicability and would require the AFM revision for those additional airplanes. For certain airplanes, this proposed AD would also require installing new, improved full-authority digital engine-control (FADEC) software. This proposed AD results from a report that, during landing, the thrust reverser may not re-stow completely if the throttle lever is moved into the forward thrust range immediately after the thrust reverser is applied. We are proposing this AD to prevent the flightcrew from performing a takeoff with a partially deployed thrust reverser, which could result in reduced controllability of the airplane.

The MCAI describes the unsafe condition as:

We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 525, 525A, and 525B airplanes. This AD requires you to inspect the lower wing skin structure, forward wing spar, lower fuselage skin, fairings, and the external fairing frames for corrosion; repair any damage found; apply a corrosion inhibitive sealant to the fuselage fairings before reinstalling; and disable the cockpit mounted pilot relief tube. This AD results from leaking of the cockpit mounted pilot relief tube, which caused corrosion of the airplane structure. We are issuing this AD to detect and correct any damage from corrosion of the airplane structure. Corrosion of the airplane structure could cause structural degradation and lead to structural failure of the airplane with consequent loss of control.

We are adopting a new airworthiness directive (AD) for Eurocopter Model AS 332 L2 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The European Aviation Safety Agency (EASA), the Technical Agent of France, with which we have a bilateral agreement, states in the MCAI:

The FAA is adopting a new airworthiness directive (AD) for CFM International, S.A. CFM56-7B series turbofan engines. This AD requires revising the Airworthiness Limitations Section (ALS) in the Engine Shop Manual (ESM) and the air carrier's approved continuous airworthiness maintenance program (CAMP) to add mandatory inspections of certain low pressure turbine rear frames (TRFs) to the ALS or CAMP. This AD results from a refined lifing analysis by the engine manufacturer that shows the need to identify an initial threshold for inspecting certain TRFs. We are issuing this AD to prevent failure of the TRF from low-cycle fatigue cracks. Failure of the TRF could result in engine separation from the airplane, which could lead to loss of control of the airplane.

This action proposes to establish Class E5 airspace at Indianapolis, IN. Additional controlled airspace is necessary to accommodate aircraft using new RNAV Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAP). The FAA is proposing this action to enhance the safety and management of Instrument Flight Rules (IFR) aircraft operations at Hendricks County-Gordon Graham Field Airport, Indianapolis, IN.

This action proposes to establish Class E airspace at Kobuk, AK. Two Standard Instrument Approach Procedures (SIAPs) are being developed for the Kobuk Airport at Kobuk, AK. Additionally, a textual departure procedure (DP) is being developed. Adoption of this proposal would result in establishment of Class E airspace upward from 700 feet (ft.) and 1,200 ft. above the surface at the Kobuk Airport, Kobuk, AK.

This action proposes to revise Class E airspace at Bettles, AK. Two Standard Instrument Approach Procedures (SIAPs) are being developed for the Bettles Airport at Bettles, AK. Additionally, two SIAPs and a textual departure procedure (DP) are being amended. Adoption of this proposal would result in revision of existing Class E airspace upward from 700 feet (ft.) and 1,200 ft. above the surface at the Bettles Airport, Bettles, AK.

This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-120 series airplanes. That action would have required repetitive calibration testing of potentiometers to detect noisy signals, replacement of only those with noisy signals, and reporting results of the calibration tests of the potentiometers and the readouts of the flight data recorder (FDR) to the airplane manufacturer. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has determined that while a noisy or defective potentiometer may hamper the ability to access certain aircraft data in support of either an accident or incident investigation or just general maintenance activities, there is no direct effect on the aircraft's ability to be operated safely. Accordingly, the proposed rule is withdrawn.

We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 747 airplanes. This proposed AD would require modification of the refuel valve control unit for the reserve fuel tanks. This proposed AD would also require a revision to the FAA- approved maintenance program to incorporate airworthiness limitation (AWL) No. 28-AWL-20 or AWL No. 28-AWL-25, as applicable. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent lightning-induced electrical energy from entering a reserve fuel tank through the refuel valve, which could result in a fuel tank explosion and consequent loss of the airplane.

The FAA is correcting typographical errors in two NPRMs that were published in the Federal Register on January 4, 2008 (73 FR 833, and 73 FR 830). The errors resulted in incorrect docket numbers. One NPRM applies to all Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. The other NPRM applies to all Bombardier Model 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. Both actions proposed to require revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems.

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

We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 172R and 172S airplanes. This AD requires you to inspect the fuel return line assembly for chafing; replace the fuel return line assembly if chafing is found; and inspect the clearance between the fuel return line assembly and both the right steering tube assembly and the airplane structure, adjusting as necessary. This AD results from reports of chafed fuel return line assemblies, which were caused by the fuel return line assembly rubbing against the right steering tube assembly during full rudder pedal actuation. We are issuing this AD to detect and correct chafing of the fuel return line assembly, which could result in fuel leaking under the floor and fuel vapors entering the cabin. This condition could lead to fire under the floor or in the cabin area.

The FAA invites public comments about our intention to request the Office of Management and Budget's (OMB) revision of a current information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on October 29, 2007, vol. 72, no. 208, page 61199-61200. Information collected is used to determine certification eligibility of Flight Engineers and Flight Navigators.

The FAA invites public comments about our intention to request the Office of Management and Budget's (OMB) revision of a current information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on October 29, 2007, vol. 72, no. 208, pages 61198-61199. The DOT/FAA certification program is implemented by Title 14 CFR parts 61 and 67. The parts prescribe minimum airman medical standards, and duration of a medical certificate.

This action proposes to amend the Class E airspace area at Factoryville, PA, to accommodate a new Standard Instrument Approach Procedure (SIAP) that has been developed for Seamans Field. This proposal would enhance the safety and management of IFR operations at Seamans Field, Factoryville, PA.

The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-135 airplanes; and Model EMB-145, -145ER, - 145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This AD requires inspections to detect discrepancies of the components of the elevator control system, repetitive movements of the control column to observe the normal response of the elevators, repetitive inspections to detect discrepancies of the skin of the elevators, and applicable related investigative actions and corrective actions. This AD also provides for optional terminating actions for the inspections and measurements. This AD results from a report indicating that a Model EMB-145 airplane did not rotate in response to the command from the yoke during take-off, which resulted in a rejected take-off. We are issuing this AD to detect and correct discrepancies of the elevator control system, which could result in reduced control of the elevators and consequent reduced controllability of the airplane.

This action establishes Class E Airspace at Marienville, PA to support a new Area Navigation (RNAV) Global Positioning System (GPS) Special Instrument Approach Procedure (IAP) that has been developed for medical flight operations into the East Marien High School Heliport. This action enhances the safety and management of Instrument Flight Rule (IFR) operations by providing that required controlled airspace to protect for this approach near the high school in Marienville, PA.

This action establishes Class E Airspace at new Albany, MS. Airspace is needed to support new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) that have been developed for New Albany-Union County Airport. This action enhances the safety and management of Instrument Flight Rule (IFR) operations in the area by providing the required controlled airspace to protect for these approaches around new Albany, MS.

This action proposes special conditions for the Embraer Model EMB-500 airplane. This airplane will have a novel or unusual design feature(s) associated with airspeed system. 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 are adopting a new airworthiness directive (AD) for Eurocopter France Model AS 355 F2 and AS 355 N helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The European Aviation Safety Agency, the Technical Agent for France, with which we have a bilateral agreement, states in the MCAI:
