Federal Aviation Administration October 2015 – Federal Register Recent Federal Regulation Documents

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain CFM International S.A. (CFM) CFM56-7B and CFM56-3 turbofan engines. Four headings in the Compliance section are incorrect. This document corrects the errors. In all other respects, the original document remains the same.

This action amends Class E airspace at Albion Municipal Airport, Albion, NE; Rock County Airport, Bassett, NE; and Jim Kelly Field Airport, Lexington, NE. Decommissioning of the non-directional radio beacons (NDBs) and/or cancellation of NDB approaches due to advances in Global Positioning System (GPS) capabilities has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the above airports. Also, the geographic coordinates are being updated for Rock County Airport and Jim Kelly Field Airport.

This action amends Class E airspace at Tekamah Municipal Airport, Tekamah, NE. A Class E extension is no longer required due to the decommissioning of the Tekamah VHF Omni-directional radio range (VOR) facility and its associated standard instrument approach procedures (SIAPs). This enhances the safety and management of instrument flight rules (IFR) operations at the airport.

We propose to supersede airworthiness directive (AD) 2010-23- 02 for Eurocopter France (now Airbus Helicopters) Model SA-365N, SA- 365N1, AS-365N2, and AS 365 N3 helicopters. AD 2010-23-02 currently requires amending the Limitations section of the Rotorcraft Flight Manual (RFM) to limit the never-exceed velocity (VNE) to 150 Knots Indicated Air Speed (KIAS) and to add a 1,500 ft/minute rate of descent (R/D) limitation beyond 140 KIAS. Since we issued AD 2010-23-02, a design change designated as modification (MOD) 0755B28 improved the dynamic behavior of the horizontal stabilizer such that AD actions are not required. This proposed AD would retain the requirements of AD 2010-23-01 and revise the applicability to exclude helicopters with MOD 0755B28. These proposed actions are intended to exclude certain helicopters from the applicability and restrict the VNE on other helicopters to prevent failure of the horizontal stabilizer and subsequent loss of control of the helicopter.

We propose to supersede Airworthiness Directive (AD) 2014-17- 51, for certain Bombardier, Inc. Model CL-600-2B16 airplanes. AD 2014- 17-51 currently requires inspecting the inboard flap fasteners of the hinge-box forward fitting at Wing Station (WS) 76.50 and WS 127.25 to determine the orientation and condition of the fasteners, as applicable, and replacement or repetitive inspections of the fasteners if necessary. AD 2014-17-51 also provides for optional terminating action for the requirements of that AD. Since we issued AD 2014-17-51, we have determined that additional action is necessary. This proposed AD would also require accomplishment of the previously optional terminating action. We are proposing this AD to detect and correct incorrectly oriented or fractured fasteners, which could result in premature failure of the fasteners attaching the inboard flap hinge-box forward fitting; failure of the fasteners could lead to the detachment of the flap hinge box and the flap surface, and consequent loss of control of the airplane.

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 premature aging of certain passenger chemical oxygen generators that resulted in the generators failing to activate. This proposed AD would require an inspection to determine if certain passenger chemical oxygen generators are installed and replacement of affected passenger chemical oxygen generators. We are proposing this AD to prevent failure of the passenger chemical oxygen generator to activate and consequently not deliver oxygen during an emergency, possibly resulting in injury to the airplane occupants.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400, -401, and -402 airplanes. This proposed AD was prompted by reports of chafing damage due to insufficient clearance on the main landing gear (MLG) stabilizer brace, the nacelle A-frame structure, and the adjacent electrical wiring harnesses. An insufficient fillet radius may also exist on certain airplanes. This proposed AD would require, depending on airplane configuration, an inspection of the nacelle A-frame structure for insufficient fillet radius; an inspection for cracking of affected structure, and rework or repair if necessary, and rework of the nacelle A-frame structure; repetitive inspections of the nacelle A-frame structure and the MLG stabilizer brace for insufficient clearance and damage, and repair if necessary, and rework of the nacelle A-frame structure, which would terminate the repetitive inspections; installation of new stop brackets and a shim on each MLG stabilizer brace assembly; and rework of the electrical wiring harnesses in the nacelle area. We are proposing this AD to detect and correct chafing damage and subsequent premature cracking and fracture of the nacelle A- frame structure, which could result in failure of the MLG stabilizer brace and loss of the MLG down-lock indication, which could adversely affect the safe landing of the airplane.

This action establishes Class E airspace at Tomah, WI. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures at Bloyer Field Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations at the airport.

This action proposes to establish Class E surface area airspace designated as an extension to the Class D airspace at Whiteman Airport, Los Angeles, CA. After reviewing the airspace, the FAA found it necessary to establish Class E surface area for the safety and management of Instrument Flight Rules (IFR) operations for at the airport.

This action establishes Class E airspace at Cottonwood Airport, Cottonwood, AZ, to accommodate new Standard Instrument Approach Procedures (SIAP) at the airport. The FAA found establishment of controlled airspace necessary for the safety and management of Instrument Flight Rules (IFR) operations.

This action amends Class E Airspace at Ashland, VA as new Standard Instrument Approach Procedures have been developed at Hanover County Municipal Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport. This action also updates the geographic coordinates of the airport.

This action amends Class E Airspace at Ponce, PR, as the PONCE VHF Omni-Directional Radio Range Tactical Air Navigation Aid, (VORTAC) has been decommissioned, requiring airspace redesign at Mercedita Airport. This action enhances the safety and management of Instrument Flight Rules (IFR) operations at the airport.

This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

This action amends Restricted Areas R-3602A and R-3602B, Manhattan, KS, to accurately identify the R-3602A and R-3602B boundary segments described using the Chicago, Rock Island and Pacific Railroad right-of-way, the R-3602A and R-3602B shared boundary segment described using Old U.S. Highway 77, and the R-3602A and Riley Military Operations Area (MOA) shared boundary segment described using the Milford Reservoir shoreline. The restricted area ceilings are also amended to be expressed as flight levels (FL), the Marshall Army Air Field Radio Beacon (RBN) referenced in R-3602B is changed to the Cavalry Nondirectional Beacon (NDB), and the restricted areas using agency information is updated to include the military service of the using agency. This action does not affect the overall restricted area boundaries, designated altitudes, times of designation, or activities conducted within the restricted areas. Additionally, boundary segment amendments of the Riley MOA, ancillary to the restricted area amendments, are being made. Since the R-3602A and R-3602B restricted areas share boundaries with the Riley MOA, the FAA included discussion of the Riley MOA amendments in this rule. Lastly, the MOA using agency is being amended to match the restricted areas using agency information.

We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-28-161, PA-28-181, and PA-28R-201 airplanes. This AD requires inspecting the right wing rib at wing station 140.09 for cracks and taking necessary corrective action. This AD was prompted by a report of cracks found in the wing rib bead radius that were formed during production. We are issuing this AD to correct the unsafe condition on these products.

We are superseding airworthiness directive (AD) 2014-14-02 for certain Pratt & Whitney Canada Corp. (P&WC) PW120, PW121, PW121A, PW124B, PW127, PW127E, PW127F, PW127G, and PW127M turboprop engines. AD 2014-14-02 required removal of the O-ring seal from the fuel manifold fitting. This new AD requires replacement of the fuel nozzle and the fuel manifold flow adapter. This AD was prompted by reports of fuel leaks at the interface between the fuel manifold and the fuel nozzle that resulted in engine fire. We are issuing this AD to correct the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for Schempp-Hirth Flugzeugbau GmbH Models Duo Discus and Duo Discus T powered sailplanes. 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 excessive load on the air brake system. We are issuing this AD to require actions to address the unsafe condition on these products.

The FAA is issuing this notice to advise the public of the sixty-fourth Special Committee 186 meeting.

We propose to adopt a new airworthiness directive (AD) for certain Dowty Propellers R352/6-123-F/1, R352/6-123-F/2, and R410/6- 123-F/35 model propellers. This proposed AD was prompted by reports of dowel hole cracks in the face of the rear hub half. This proposed AD would require a records review to determine repair status and marking the affected propeller hubs as required. This proposed AD would also require installing dowel hole liners as necessary. We are proposing this AD to prevent loss of structural integrity of the propeller hub, which could result in damage to the propeller and damage to the airplane.

We propose to supersede airworthiness directive (AD) 2013-11- 13 that applies to all Rolls-Royce plc (RR) Viper Mk. 601-22 turbojet engines. Since we issued AD 2013-11-13, RR determined that additional parts for the RR Viper Mk. 601-22 as well as additional engine models are affected. This proposed AD would add two new engine models and additional engine parts to the applicability. We are proposing this AD to prevent failure of life-limited parts, which could lead to an uncontained part release, damage to the engine, and damage to the airplane.

We are adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model GVI airplanes. This AD was prompted by reports of corrosion on in-service air non-return valves. This AD requires a revision to the Emergency Procedures section of the airplane flight manual (AFM). This AD also requires a revision to the maintenance or inspection program, as applicable, to incorporate airworthiness limitations for the high pressure (HP) Stage 5 air non- return valves. We are issuing this AD to ensure the flightcrew is provided with procedures to mitigate the risks associated with failure of the HP Stage 5 air non-return valve. Failure of the HP Stage 5 air non-return valve in the open position could result in engine instability and uncommanded in-flight shutdown.

We are adopting a new airworthiness directive (AD) for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 188 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating the left and right lower surface panels of the wings are subject to widespread fatigue damage (WFD). This AD requires repetitive inspections for cracking at these panels, and repair if necessary. The AD also requires a one-time bolt- hole eddy current inspection of all open holes for cracking, repair if necessary, and modification. We are issuing this AD to prevent fatigue cracking of the left and right lower surface panels of the wings, which could result in reduced structural integrity of the airplane.

We are adopting a new airworthiness directive (AD) for all Model FAN JET FALCON, FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This AD was prompted by reports of defective fire extinguisher tubes. It was determined the defects were caused by corrosion. This AD requires repetitive general visual inspections of the fire extinguisher tubes for cracking and corrosion, and replacement of any cracked tube with a serviceable tube, if necessary. We are issuing this AD to detect and correct cracking and corrosion in the fire extinguisher tubes, which could impact the capability to extinguish an engine fire, and possibly result in damage to the airplane and injury to the passengers.

This action amends Restricted Areas R-3601A and R-3601B, Brookville, KS, to re-define the restricted area boundary segments described using the Missouri Pacific Railroad Track visual landmark. The restricted areas using agency information is also updated to include the military service of the using agency. This action does not affect the overall restricted area boundaries, designated altitudes, times of designation, or activities conducted within the restricted areas. Additionally, boundary segment amendments of the Smoky and Smoky High military operations areas (MOA), ancillary to the restricted areas amendments, are being made. Since R-3601A and R-3601B share boundaries with the Smoky and Smoky High MOAs, the FAA included discussion of the Smoky and Smoky High MOAs amendments in this rule. Lastly, the MOAs using agency is being amended to match the restricted areas using agency information.
