Rotorcraft External-Load Operations; Technical Amendment
The FAA is correcting two regulatory cross-references. The pertinent section was not amended to reflect changes that were implemented in the final rule dated November 7, 1986 (Doc. No. 24550, 51 FR 40692, 40708).
Proposed Amendment of Class E Airspace, Willows, CA
This action proposes to modify Class E airspace extending upward from 700 feet above the surface at Willows-Glenn County Airport, Willows, CA. Decommissioning of the Maxwell VHF Omni-directional Range/ Tactical Air Navigation (VORTAC) navigation aid and cancellation of associated approaches has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport. The airport's geographic coordinates also would be adjusted to match the current FAA aeronautical database.

Wyatt Airport, Realitos, TX; and Jasper County-Bell Field, Jasper, TX. Decommissioning of non- directional radio beacons (NDB), cancellation of NDB approaches, and implementation of area navigation (RNAV) procedures have made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the above airports. This action also updates the geographic coordinates for Corpus Christi International Airport; the Corpus Christi VORTAC; Aransas County Airport, Rockport, TX; Nueces County Airport, Robstown, TX; Dallas/Fort Worth International Airport, Dallas/Fort Worth, TX; McKinney National Airport, McKinney, TX; Lancaster Airport; Bourland Field Airport, Fort Worth, TX; Jasper County-Bell Field; and Alfred C. `Bubba' Thomas (formerly San Patricio County Airport), Sinton, TX, to coincide with the FAA's aeronautical database. Also, the names of McCampbell-Porter Airport (formerly T.P. McCampbell Airport); McKinney National Airport (formerly Collin County Regional Airport); Ralph M. Hall/Rockwall Municipal Airport (formerly Rockwall Municipal Airport); and Alfred C. `Bubba' Thomas (formerly San Patricio County Airport) are being updated to coincide with the FAA's aeronautical database.
Establishment of Class E Airspace, Silver Springs, NV
This action establishes Class E airspace extending upward from 700 feet above the surface at Silver Springs Airport, Silver Springs, NV. The FAA found establishment of airspace necessary for the safety and management of Instrument Flight Rules (IFR) operations under new Area Navigation (RNAV) Standard Instrument Approach Procedures at the airport.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-8 and 747-8F series airplanes. This AD was prompted by a report that static strength analysis has shown that the aluminum transmission aft bearing plate assemblies have inadequate structural strength for one or more of the required load cases. This AD requires removing aluminum transmission aft bearing plate assemblies from the flap track and installing titanium transmission aft bearing plate assemblies to the flap track. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, and -106 airplanes; and Model DHC-8-200 and -300 series airplanes. This AD was prompted by a report of heat damage found on a nacelle firewall after an unsuccessful engine ground start and several events of heat damage found on direct current starter/generator terminal block assemblies. This AD requires an inspection to detect damage on the nacelle firewalls and the terminal block assemblies and to make sure the insulating sleeves are installed and have no damage, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters
We are adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation Model S-76D helicopters. This AD requires revising the rotorcraft flight manual (RFM) to prohibit Barometric Altitude Hold (ALT) mode beyond a certain rate of climb or descent. This AD is prompted by a report of the autopilot being unable to maintain level flight during certain flight conditions. The actions specified by this AD are intended to prevent a significant pilot workload increase, pilot disorientation, and subsequent loss of control of the helicopter.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are superseding Airworthiness Directive (AD) 2013-02-08 for all Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2013-02-08 required inspection of the trunnions and upper and lower pins of the horizontal stabilizer trim actuator (HSTA), and replacement or re-identification if necessary; and revision of the maintenance program to include safe life limits and inspection requirements for the HSTA. This new AD requires certain actions related to the trunnions and pins for the HSTA, revising the maintenance or inspection program, and removing certain airplanes from the applicability. This AD was prompted by a determination that not all affected attachment pins and trunnions were included in the inspections required by AD 2016-02-08, and that incorrect attachment hardware may have been used in replacements on certain airplanes. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-400 series airplanes. This AD was prompted by reports of cracks in the upper chord of the overwing stub beams at body station (STA) 578 emanating from the rivet location common to the crease beam inner chord and the overwing stub beam upper chord. This AD requires repetitive inspections for cracking, and related investigative and corrective actions if necessary. We are issuing this AD to prevent the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters
The FAA is withdrawing a notice of proposed rulemaking (NPRM). The NPRM proposed to supersede airworthiness directive (AD) 2007-25-08 for Eurocopter France (now Airbus Helicopters) Model SA-365N1, AS- 365N2, AS 365 N3, SA-366G1, EC 155B, and EC155B1 helicopters. The proposed actions were intended to prevent damage to the tail gearbox (TGB) control shaft and rod assembly bearing resulting in end play, loss of tail rotor pitch control, and subsequent loss of control of the helicopter. Since we issued the NPRM, we have received reports of new occurrences of loss of yaw control due to failure of the control rod bearing and determined that different actions at shorter time intervals are necessary to correct the unsafe condition. Accordingly, we withdraw the proposed rule.
Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters
We are superseding Airworthiness Directive (AD) 2007-25-08 for Eurocopter France (now Airbus Helicopters) Model SA-365N1, AS-365N2, AS 365 N3, SA-366G1, EC 155B, and EC155B1 helicopters. AD 2007-25-08 required checking the tail rotor gearbox (TGB) oil, inspecting the magnetic plug, and either replacing the TGB or performing additional inspections. This AD was prompted by reports of new occurrences of loss of yaw control due to failure of the control rod bearing. This AD requires checking the TGB oil level and replacing the bearing with a new part-numbered bearing. These actions are intended to detect and prevent damage to the bearing resulting in end play, loss of tail rotor pitch control, and subsequent loss of control of the helicopter.
Airworthiness Directives; Airbus Defense and Space S.A. (Formerly Known as Construcciones Aeronauticas, S.A.) Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Defense and Space S.A. Model CN-235, CN 235-100, CN 235-200, and CN 235-300 airplanes, and Model C-295 airplanes. This proposed AD was prompted by leakage of a motorized cross-feed fuel valve. This proposed AD would require an inspection of the affected fuel valves and, depending on findings, applicable corrective action(s). We are proposing this AD to detect and correct leaks in a motorized cross-feed fuel valve, which could lead to failure of the fuel valve and consequent improper fuel system functioning or, in case of the presence of an ignition source, an airplane fire.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2006-19-12 for certain The Boeing Company Model 777-200 and -300 series airplanes. AD 2006-19-12 required inspecting the lower web of the aft fairing of the engine struts for any discoloration, and doing related investigative and corrective actions if necessary; inspecting the heat shield castings for any damage and doing corrective action if necessary; installing gap cover strips; and replacing insulation blankets with new insulation blankets. This new AD retains those requirements and also requires, depending on airplane configuration, one-time or repetitive detailed inspections for cracking and deformation, as applicable, of the aft fairing lower structure, and one-time or repetitive conductivity inspections of the aft fairing lower structure, and related investigative and corrective actions if necessary. This new AD also adds airplanes to the applicability. This AD was prompted by a report that an aft fairing lower spar web exceeded the allowable conductivity limits. We are issuing this AD to address the unsafe condition on these products.
