Federal Aviation Administration June 2018 – Federal Register Recent Federal Regulation Documents

This action proposes to amend Class D airspace at San Marcos Regional Airport, Austin, TX; establish Class E airspace designated as a surface area at Georgetown Municipal Airport, Georgetown, TX, and San Marcos Regional Airport; and amend Class E airspace extending upward from 700 feet above the surface at San Marco Regional Airport and Lockhart Municipal Airport, Lockhart, TX. The FAA is proposing this action at the request of Austin Air Traffic Control Tower (ATCT)/ Terminal Radar Approach Control (TRACON) to establish part-time Class E airspace designated as a surface area at Georgetown Municipal Airport and San Marcos Regional Airport and to review the associated airspace for the safety and management of instrument flight rule (IFR) operations at these airports. The name of San Marcos Regional Airport would be updated to coincide with the FAA's aeronautical database, and the outdated term ``Airport/Facility Directory'' would be replaced with the term ``Chart Supplement''.

This action proposes to amend Class D airspace, Class E airspace designated as a surface area, and Class E airspace extending upward from 700 feet above the surface at Chippewa Valley Regional Airport, Eau Claire, WI. The FAA is proposing this action as a result of an airspace review caused by the decommissioning of the Eau Claire nondirectional radio beacon (NDB)/outer compass locator (LOM). The name and geographic coordinates of the Chippewa Valley Regional Airport and the name of the May Clinic Health System-Eau Claire Heliport would also be updated to coincide with the FAA's aeronautical database.

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.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-300 and -300F series airplanes. This AD was prompted by reports of fatigue cracking on airplanes with Aviation Partners Boeing winglets installed. This AD requires high frequency eddy current (HFEC) inspections for cracking of the lower outboard wing skin, and repair or modification if necessary. This AD also requires one of three follow-on actions: Repeating the HFEC inspections, modifying certain internal stringers and oversizing and plugging the existing fastener holes of the lower wing, or modifying the external doubler/tripler and doing repetitive post-modification inspections. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain Airbus Model A350-941 airplanes. This AD requires a detailed inspection of the four retaining pins in the main landing gear support structure (MLGSS) trunnion block, left- and right-hand sides, and related investigative and corrective actions if necessary. This AD was prompted by a determination that short retaining pins may have been installed at the incorrect location of the MLGSS forward pintle. We are issuing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2014-02-01, which applied to certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), and Model CL-600-2D24 (Regional Jet Series 900) airplanes. AD 2014-02-01 required repetitive inspections of the rudder travel limiter (RTL) return springs and primary actuator, and corrective actions if necessary; and replacement of certain RTL return springs. This AD requires an inspection of the RTL return springs for signs of chafing; an inspection of the casing of the primary actuator for signs of chafing or missing paint; replacement of the RTL return springs; and an inspection of the lugs of the RTL limiter arm assembly for cracks, and modification or replacement, as applicable; and applicable corrective actions. This AD also adds airplanes to the applicability. This AD was prompted by reports that when installing the RTL return springs, the RTL limiter arm assembly lug(s) can become deformed. We are issuing this AD to address the unsafe condition on these products.

This action corrects a final rule published in the Federal Register on May 17, 2018, amending Class D and Class E airspace at Greenwood, MS, by removing duplicative language added in the legal description of Class E airspace extending upward from 700 feet or more above the surface for Greenwood-Leflore Airport.

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 Freighter series airplanes; Airbus Model A330-200 series airplanes; and Airbus Model A330-300 series airplanes. This proposed AD was prompted by reports of Angle of Attack (AOA) blockages not detected by upgraded flight control primary computer (FCPC) software standards. This proposed AD would require upgrading certain FCPCs, which would terminate a certain airplane flight manual revision for certain airplanes. We are proposing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2017-01-07, which applied to all Dassault Aviation Model FAN JET FALCON airplanes; Model FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE- FALCON 200 airplanes; Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20- F5 airplanes; and Model MYSTERE-FALCON 50 airplanes. AD 2017-01-07 required a functional test or check of the main entry door closure and warning system, and applicable door closing inspections, adjustments, operational tests, and corrective actions if necessary. This AD requires repetitive door closing inspections, adjustments, operational tests, and corrective actions if necessary. This AD was prompted by a report indicating that during approach for landing, the main entry door detached from an airplane. We are issuing this AD to address the unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 2006-07- 26, which applies to all ATR-GIE Avions de Transport R[eacute]gional Model ATR42 airplanes. AD 2006-07-26 requires a one-time inspection to detect discrepancies (e.g., cracking, loose/sheared fasteners, distortion) of the upper skin and rib feet of the outer wing boxes, and repair if necessary. Since we issued AD 2006-07-26, we have received reports of cracking in these same areas on other Model ATR42 airplanes. This proposed AD would require repetitive inspections to detect discrepancies of the upper skin and rib feet of the outer wing boxes, and repair if necessary. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 2000 and FALCON 2000EX airplanes. This proposed AD was prompted by reports of metallic debris found in the wing slat piccolo tubes; investigation revealed that the debris originated from the flow guide of the ball joint of the wing anti-ice valve. This proposed AD would require repetitive inspections for metallic debris and damage of the flow guide of the ball joint of the wing anti-ice valve, and related investigative and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.

We propose to revise Airworthiness Directive (AD) 2014-05-06 for Eurocopter Deutschland GmbH Model EC135 and MBB-BK 117C-2 helicopters. AD 2014-05-06 requires repetitive inspections of the flight-control bearings, replacing any loose bearings with airworthy flight-control bearings, and installing bushings and washers. This proposed AD would retain the requirements of AD 2014-05-06 but would remove the repetitive inspections. The actions of this proposed AD are intended to correct an unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 427 helicopters. This proposed AD would require inspecting the inboard skin of the vertical fin around the four tailboom attachment points. This proposed AD is prompted by reports of cracked vertical fin skins that resulted from metal fatigue. The actions of this proposed AD are intended to prevent an unsafe condition on these products.
