Federal Aviation Administration February 2014 – Federal Register Recent Federal Regulation Documents

These special conditions are issued for the Bombardier Inc. Models BD-500-1A10 and BD-500-1A11 series airplanes. These airplanes will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These features are associated with an aluminum- lithium fuselage construction that may provide different levels of protection from post-crash fire threats than similar aircraft constructed from traditional aluminum structure. 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.

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 to renew an information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on December 12, 2013, vol. 78, no. 239, page 75671. Respondents to this survey are owners of general aviation aircraft. This information is used by FAA, NTSB, and other government agencies, the aviation industry, and others for safety assessment, planning, forecasting, cost/benefit analysis, and to target areas for research.

We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by a report that an investigation showed that when a certain combination of a target/proximity sensor serial number is installed on a flap interconnecting strut, a ``target FAR'' signal cannot be detected when it reaches the mechanical end stop of the interconnecting strut. This AD requires an inspection to determine the part number of the interconnecting struts installed on the wings, identifying the part number and the serial number of the associated target and proximity sensor if applicable, and replacing or re-identifying the flap interconnecting strut if applicable. We are issuing this AD to detect and correct a latent failure of the flap down drive disconnection due to an already-failed interconnecting strut sensor, which could result in asymmetric flap panel movement and consequent loss of control of the airplane.

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This AD requires repetitive inspections for fractured or incorrectly oriented fasteners on the inboard flap hinge-box forward fittings on both wings, and fastener replacement if necessary. This AD was prompted by two reports of fractured fastener heads found on the inboard flap hinge-box forward fitting. We are issuing this AD to detect and correct incorrectly oriented or fractured fasteners, which could result in detachment of the flap hinge-box and the flap surface, and consequent reduced controllability of the airplane.

We are adopting a new airworthiness directive (AD) for various restricted category helicopters, originally manufactured by Bell Helicopter Textron, Inc. (Bell), model numbers HH-1K, TH-1F, TH-1L, UH- 1A, UH-1B, UH-1E, UH-1F, UH-1H, UH-1L, and UH-1P. This AD requires inspecting the tail rotor (T/R) cable assembly for an incorrectly machined body. This AD is prompted by a report from Bell that a defective body on the cable prevents the barrel assembly from fully engaging in the body cavity. These actions are intended to prevent disengagement of the cable from the barrel, failure of the T/R pitch control, and subsequent loss of control of the helicopter.

We are adopting a new airworthiness directive (AD) for certain ATRGIE Avions de Transport R[eacute]gional Model ATR42 and Model ATR72 airplanes. This AD was prompted by reports of defective sealing between the nacelle lower fairing and the underwing box. This AD requires a one-time general visual inspection for damaged (worn, torn, or abraded) or missing seals between the nacelle lower fairing and the underwing box of both the left-hand and right-hand engine nacelles, and replacement of the seal and/or shims if necessary. We are issuing this AD to prevent the decrease of the fire extinguishing agent efficiency, which could delay fire extinction and allow fire propagation out of the nacelle fire protected area, resulting in damage to the airplane.

We propose to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-725A1-12 turbofan engines. This proposed AD was prompted by reports of wear on the receptors of the double-ended unions in the fuel metering unit (FMU) housing on BR700-725A1-12 engines causing fuel leakage. This proposed AD would require removal of the affected FMUs. We are proposing this AD to prevent failure of the FMU, which could lead to damage to one or more engines and damage to the airplane.

This action amends the Class D and Class E airspace at Christiansted, St. Croix, VI, by adjusting the geographic coordinates of Henry E. Rohlsen Airport. The airport name also is changed from Alexander Hamilton Airport. This action brings current the effected charting and enhances airspace management within the National Airspace System.

This action amends Class E Airspace at McMinnville, TN, as the Warri Non-Directional Beacon (NDB) has been decommissioned and new standard instrument approach procedures developed for Instrument Flight Rules (IFR) operations at Warren County Memorial Airport. This enhances the safety and management of aircraft operations at the airport.

This action proposes to establish Class E Airspace at Geneva, AL, to accommodate a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) serving Geneva Municipal Airport. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations within the National Airspace System.

This action proposes to establish Class E Airspace at Blairsville, GA, to accommodate a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAP) serving Blairsville Airport. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations within the National Airspace System.

This action proposes to establish Class E Airspace at Nashville, TN, to accommodate a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) serving Nashville International Airport. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations within the National Airspace System.

We propose to supersede Airworthiness Directive (AD) 2010-17- 18 R1, which applies to certain Air Tractor, Inc. Models AT-802 and AT- 802A airplanes. AD 2010-17-18 R1 currently requires repetitively inspecting (using the eddy current method) the two outboard fastener holes in both of the wing main spar lower caps at the center splice joint for cracks; repairing or replacing any cracked spar; changing the safe life for certain serial number ranges; and sending the inspection results, only if cracks are found, to the FAA. Since we issued AD 2010- 17-18 R1, we have determined that the safe life for the wing main spar lower caps should apply to all AT-802 and AT-802A airplanes regardless of configuration or operational use. This proposed AD would retain all actions of AD 2010-17-18 R1 and expand the applicability to include all serial numbers regardless of configuration or operational use. We are proposing this AD to correct the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 407 helicopters. This proposed AD would require inspecting the aft fuselage upper skin (upper skin) for a crack and the upper left longeron assembly (longeron assembly) for a crack, corrosion, or defect. This AD would require replacing or repairing a part or section, depending on the inspection's outcome. This proposed AD is prompted by reports of cracks in the upper left-hand longeron. The proposed actions are intended to prevent failure of the longeron assembly or the upper skin, which could lead to a structural failure and loss of helicopter control.

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 to renew a generic information collection. As part of a Federal Government-wide effort to streamline the process to seek feedback from the public on service delivery, FAA has an approved Generic Information Collection Request (Generic ICR): ``Generic Clearance for the Collection of Qualitative Feedback on Agency Service Delivery.''

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 to renew an information collection. The information collected is used to determine if applicants are medically qualified to perform the duties associated with the class of airman medical certificate sought.

The FAA is issuing this notice to advise the public of the thirty-sixth meeting of the RTCA Special Committee 206, Aeronautical Information and Meteorological Data Link Services.

The FAA is issuing this notice to advise the public of the fifteenth meeting of the RTCA Special Committee 222, Inmarsat AMS(R)S.

This action proposes to modify the Class E airspace areas at Redmond, OR, to accommodate Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures for Instrument Flight Rules (IFR) operations at Roberts Field. This action, initiated by the biennial review of the Redmond, OR, airspace area, would enhance the safety and management of IFR operations at the airport.

We are revising an earlier proposed airworthiness directive (AD) for all Airbus Model A318 series airplanes, and Model A319, A320, and A321 series airplanes. The NPRM proposed identifying the part number and serial number of each passenger oxygen container, replacing the oxygen generator manifold of the affected oxygen container with a serviceable manifold, and performing an operational check of the manual mask release, and corrective actions if necessary. The NPRM was prompted by reports of silicon particles inside the oxygen generator manifolds, which had chafed from the mask hoses during installation onto the generator outlets. This action revises the NPRM by adding airplanes to the applicability, adding a new check for part numbers, corrective actions if necessary, and reducing the compliance time for certain actions. We are proposing this AD to detect and correct non- serviceable oxygen generator manifolds, which could reduce or block the oxygen supply and result in injury to passengers when oxygen supply is needed. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 707 airplanes, and Model 720 and 720B series airplanes. This proposed AD was prompted by reports of scribe-line- related fatigue cracks on Model 727 airplanes, which are similar in design to Model 707 airplanes, and Model 720 and 720B series airplanes. This proposed AD would require inspections for scribe lines in the skin lap joints, external approved repairs, external features, skin butt joints, and decals, and related investigative and corrective actions if necessary. This proposed AD would also require surface finish restoration. We are proposing this AD to detect and correct scribe lines, which can develop into fatigue cracks in the skin and cause rapid decompression of the airplane.

We propose to supersede Airworthiness Directive (AD) 98-13-23, which applies to certain Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). AD 98-13-23 requires inspections to detect corrosion and cracking of the lower horizontal stabilizer cutout longeron, the corner fitting, the skin strap, and the outer skin; and repair, if necessary. Since we issued AD 98-13-23, we have determined that the risk of cracking is higher than initially determined. This proposed AD would reduce the compliance times and repetitive intervals, and changes the inspection procedures. We are proposing this AD to prevent cracking of the lower horizontal stabilizer cutout longeron, the corner fitting, the skin strap, and the outer skin, which could result in reduced structural integrity of the horizontal-stabilizer cutout longeron.

These special conditions are issued for the Bombardier Aerospace Inc. Models BD-500-1A10 and BD-500-1A11 series airplanes. These airplanes will have novel or unusual design features associated with the autobraking system for use during landing. 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.

We are superseding Airworthiness Directive (AD) 2011-03- 13 for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and Model CL-600-2D24 (Regional Jet Series 900) airplanes. AD 2011-03-13 required repetitive inspections of the rudder travel limiter (RTL) return springs and primary actuator, and corrective actions if necessary. This new AD requires replacing certain RTL return springs, including doing related investigative and corrective actions, if necessary; which is terminating action for the repetitive inspections. This new AD also revises the applicability. This AD was prompted by reports of failure of the RTL return spring. We are issuing this AD to prevent failure of the RTL, which would permit an increase of rudder authority beyond normal structural limits and consequently affect the controllability of the airplane.

We are adopting a new airworthiness directive (AD) for all Bae Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes. This AD was prompted by reports of excess solder deposited during overhaul on the frangible plug of a fire extinguisher, which prevented the release of the extinguishant. This AD requires a one-time inspection of certain engine and auxiliary power unit (APU) fire extinguishers to determine if the fire extinguishers are affected by excessive solder and corrective actions if necessary. We are issuing this AD to prevent the failure of a fire extinguisher to discharge, which reduces the ability of the fire protection system to extinguish fires in the engine or APU fire zones, possibly resulting in damage to the airplane and injury to the passengers.
