Harmonization of Airworthiness Standards-Fire Extinguishers and Class B and F Cargo Compartments; Correction
The FAA is correcting a final rule published on February 16, 2016. In that rule, the FAA amended certain airworthiness regulations for transport category airplanes by upgrading fire safety standards for Class B cargo compartments; establishing fire safety standards for a new type of cargo compartment, Class F; and updating related standards for fire extinguishers. This amendment eliminated certain regulatory differences between the airworthiness standards of the FAA and the European Aviation Safety Agency (EASA), without affecting current industry design practices. However, in that document, the amendment number for the final rule was incorrect, and this document now posts the correct amendment number.
Agency Information Collection Activities: Requests for Comments; Clearance of Renewed Approval of Information Collection: Small Unmanned Aircraft Registration System (sUAS)
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 previously approved information collection. Aircraft registration is necessary to ensure personal accountability among all users of the national airspace system. Aircraft registration also allows the FAA and law enforcement agencies to address non-compliance by providing the means by which to identify an aircraft's owner and operator.
Fifth Meeting: RTCA Special Committee (233) Addressing Human Factors/Pilot Interface Issues for Avionics
The FAA is issuing this notice to advise the public of the Fifth RTCA Special Committee 233 meeting.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and all Airbus Model A340-200, -300, -500, and -600 series airplanes. This proposed AD was prompted by reports of chafing of the feeder cable at the pylon-wing junction due to vibration; one report revealed that the cable loom plastic support bracket of the G-route was broken due to vibration; and another report revealed wire chafing due to clamp damage. This proposed AD would require modifying the cable loom support bracket of the G-route of the inboard pylons at the pylon- wing junction. We are proposing this AD to prevent chafing of the wiring in the pylon-wing area, which could result in an electrical short circuit near a flammable fluid vapor zone, and consequent fire or fuel tank explosion.
Airworthiness Directives; Dassault Aviation Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This proposed AD was prompted by a report of improperly drilled bores, located on upper and lower stiffener joints to the web at a certain frame. This proposed AD would require a one-time inspection of the bores, and repair if necessary. We are proposing this AD to detect and correct an unsatisfactory bore that can adversely affect the structural integrity of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-400, 747-400D, and 747-400F series airplanes. This proposed AD was prompted by a determination that a certain fastener type in the fuel tank walls has insufficient bond to the structure, and an electrical wiring short could cause arcing to occur at the ends of fasteners in the fuel tanks. This proposed AD would require the installation of new clamps and polytetrafluoroethylene (TFE) sleeves on the wire bundles of the front spars and rear spars of the wings. This proposed AD would also require inspecting the existing TFE sleeves under the wire bundle clamps for correct installation, and replacement if necessary. We are proposing this AD to prevent potential ignition sources in the fuel tank in the event of a lightning strike or high-powered short circuit, and consequent fire or explosion.
Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2013-10- 03, for all Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. AD 2013-10-03 currently requires one-time inspections for deformation and damage of the bogie beams of the main landing gear (MLG); repetitive inspections for damage and corrosion of the sliding piston sub-assembly on certain airplanes; and related investigative and corrective actions if necessary. Since we issued AD 2013-10-03, we have determined that certain one-time inspections are no longer necessary, certain compliance times may be extended, and an optional terminating action should be provided. This proposed AD would remove Model A340- 500, and -600 series airplanes from the applicability, remove certain one-time inspections of the MLG bogie beams and the sliding piston sub- assembly; revise certain compliance times and provide, for certain airplanes, an optional terminating action for the repetitive actions. We are proposing this AD to detect and correct damage or corrosion under the bogie stop pad of both MLG bogie beams, which could result in a damaged bogie beam and consequent detachment of the beam from the airplane, or collapse of the MLG and departure of the airplane from the runway.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 Freighter series airplanes; Model A330- 200 and A330-300 series airplanes; Model A340-200 and A340-300 series airplanes; Model A340-500 series airplanes; and Model A340-600 series airplanes. This proposed AD was prompted by a report indicating that, during an operational test of a ram air turbine (RAT), the RAT did not deploy in automatic mode. This proposed AD would require identification of the manufacturer, part number, and serial number of the RAT, and re- identifying and modifying the RAT if necessary. We are proposing this AD to prevent non-deployment of the RAT, which, if preceded by a total engine flame-out, or during a total loss of normal electrical power generation, could result in reduced control of the airplane.
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
We propose to adopt a new airworthiness directive (AD) for all Turbomeca S.A. Arriel 1D and 1D1 turboshaft engines with a pre- modification (mod) TU357 gas generator module (M03), installed. This proposed AD was prompted by reports of divergent rubbing between the piston shaft small diameter labyrinth and the rear bearing support. This proposed AD would require removing the pre-modification (mod) TU357 gas generator module (M03) and replacing with a part eligible for installation. We are proposing this AD to prevent failure of the labyrinth seal and engine, in-flight shutdown, and loss of control of the helicopter.
Proposed Amendment of Class E Airspace; Ogden-Hinckley, UT
This action proposes to modify the Class E airspace extending upward from the surface designated as an extension to the Class D surface area at Ogden-Hinckley Airport, Ogden, UT. The FAA's Aeronautical Information Services identified that the width of the Class E extension to the Class D surface area did not meet the current criteria. This action would enhance the safety and management of Standard Instrument Approach Procedures (SIAPs) for Instrument Flight Rules (IFR) operations at the airport.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2008-26-07 for all The Boeing Company Model DC-8-11, DC-8-12, DC-8-21, DC-8-31, DC-8- 32, DC-8-33, DC-8-41, DC-8-42, and DC-8-43 airplanes; Model DC-8-50 series airplanes; Model DC-8F-54 and DC-8F-55 airplanes; Model DC-8-60 series airplanes; Model DC-8-60F series airplanes; Model DC-8-70 series airplanes; and Model DC-8-70F series airplanes. AD 2008-26-07 required repetitive inspections of the lower skin and stringers at certain stations, and corrective actions if necessary. This new AD continues to require the actions specified in AD 2008-26-07 and also requires an eddy current high frequency (ETHF) inspection for cracks of the fastener open holes common to the lower skins, stringers, and splice fittings at a certain station; installation of external doublers and fasteners and repetitive eddy current low frequency (ETLF) inspections around the fasteners for any crack; and corrective actions if necessary. This AD was prompted by certain mandated programs intended to support the airplane reaching its limit of validity of the engineering data that support the established structural maintenance program. We are issuing this AD to detect and correct cracks in the lower skins, stringers, and fastener holes of the splice fittings, which could result in the loss of structural integrity of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, Model 757 airplanes, Model 767 airplanes, and Model 777 airplanes. This AD results from fuel system reviews conducted by the manufacturer. This AD requires an inspection to determine if certain motor-operated valve (MOV) actuators for the fuel valves are installed, and replacement of any affected actuators. Previous ADs addressed this Special Federal Aviation Regulation No. 88 (SFAR 88) issue for the majority of the airplanes delivered with these actuators. Since those ADs did not cover all of the airplanes, and for some airplanes delivered with improved actuators, there was no restriction on installation of replacement actuators with the unsafe condition, this additional rulemaking action is required. As with the related ADs, we are issuing this AD to prevent electrical energy from lightning, hot shorts, or fault current from entering the fuel tank through the fuel valve actuator shaft, which could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-100, -200B, -200C, -200F, -300, -400, - 400D, and -400F series airplanes. This AD was prompted by reports of significant fuselage skin damage at certain parts of the dorsal fairing, due to wear from the dorsal fairing. This AD requires repetitive detailed inspections for wear and cracks of the fuselage skin under the dorsal fairing, and related investigative and corrective actions if necessary. This AD also requires repetitive post-repair external surface high frequency eddy current inspections of the blended areas of the skin and detailed inspections of the unrepaired areas, and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct fuselage skin damage of the dorsal fairing area, which could result in skin cracking and consequent depressurization of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 757-200 and -200CB series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the lap splices at stringer (S)-14R, lower fastener row, are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive external dual frequency eddy current (DFEC) or internal high frequency eddy current (HFEC) inspections of the lap splice, inner skin fasteners, at S-14R, station (STA) 440 through STA 540, and corrective action if necessary. We are proposing this AD to detect and correct cracking of the fuselage skin lap splice. Such cracking could result in reduced structural integrity of the airplane.
Airworthiness Directives; Dassault Aviation Airplanes
We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 900EX and FALCON 2000EX airplanes. This AD was prompted by a report of significant fuel leakage at the middle position of the left outboard slat. This AD would require modifying the assembly of the slat extension mechanical stop. We are issuing this AD to prevent failure of the assembly of the slat extension mechanical stop, which if not corrected, could lead to a significant fuel leak and result in an uncontained fire.
