Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2011-17- 09 for all Airbus Model A330-200 series airplanes, -200 Freighter series airplanes, and -300 series airplanes, and AD 2012-25-12, for all Airbus Model A330-200 series airplanes and -300 series airplanes. AD 2011-17-09 currently requires revisions to certain operator maintenance documents to include new inspections. AD 2012-25-12 currently requires replacing certain main landing gear (MLG) bogie beams before reaching new reduced life limits. Since we issued AD 2011-17-09 and AD 2012-25- 12, we have determined that more restrictive instructions and/or airworthiness limitations should be incorporated into the maintenance or inspection program, as applicable. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or revised airworthiness limitation requirements. This AD results from revisions to the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness (ICA) to include new or more restrictive life limits and/or replacements. We are proposing this AD to detect and correct fatigue cracking, accidental damage, or corrosion in principal structural elements, and possible failure of certain life limited parts, which could result in reduced 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 747-100, 747-100B, 747-100B SUD, 747- 200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. This proposed AD was prompted by reports of fatigue cracks in the station 320 crown frame and in window post number 3. This proposed AD would require repetitive inspections for cracks and missing fasteners of the station 320 crown frame, cracks in the web and flange surfaces of the forward segment of window post number 3, and missing fasteners and cracks of the window upper sill; post- modification inspections for cracks of the window upper sill; one-time fastener rework; and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct fatigue cracking and missing fasteners of the station 320 crown frame, cracking of the window post number 3, and cracking of the window upper sill, which could result in an in-flight decompression and a loss of structural integrity of the fuselage.
Airworthiness Directives; Piper Aircraft, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Model PA-46-500TP airplanes. This AD was prompted by a report of the wing upper skin joints being manufactured without sealant, which allows water to enter and stay in sealed, bonded stringers. This AD requires inspecting the upper wing surface for sealant; inspecting the wing stringers for water intrusion; inspecting for deformation and corrosion if evidence of water intrusion exists; and taking corrective actions as necessary. We are issuing this AD to correct the unsafe condition on these products.
Alaska; Subsistence Collections
The National Park Service proposes to allow qualified subsistence users to collect and use nonedible fish and wildlife parts and plant materials for the creation and subsequent disposition (use, barter, or sale) of handicrafts. The rule would also (1) clarify that collecting or possessing living wildlife is generally prohibited and (2) limit the types of bait that may be used to take bears for subsistence uses.
Airworthiness Directives; General Electric Company Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for all General Electric Company (GE) GE90-76B, GE90-77B, GE90-85B, GE90-90B, and GE90-94B turbofan engines. This proposed AD was prompted by an uncontained failure of the high-pressure compressor (HPC) stage 8-10 spool, leading to an airplane fire. This proposed AD would require eddy current inspections (ECIs) or ultrasonic inspections (USIs) of the HPC stage 8-10 spool and removing from service those parts that fail inspection. We are proposing this AD to prevent failure of the HPC stage 8-10 spool, uncontained rotor release, damage to the engine, and damage to the airplane.
Energy Conservation Program: Energy Conservation Standards for Ceiling Fans
The Energy Policy and Conservation Act of 1975 (EPCA), as amended, prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including ceiling fans. EPCA also requires the U.S. Department of Energy (DOE) to periodically determine whether more-stringent, amended standards would be technologically feasible and economically justified, and would save a significant amount of energy. In this notice, DOE proposes amended energy conservation standards for ceiling fans, and also announces a public meeting to receive comment on these proposed standards and associated analyses and results.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
We are adopting a new airworthiness directive (AD) for all ATRGIE Avions de Transport R[eacute]gional Model ATR42 airplanes. This AD was prompted by several reports of a cracked floor beam at frame (FR) 26, and of discrepancies in certain wing inspection tasks in maintenance documents that could lead to errors in scheduling inspection intervals of structurally significant items (SSIs). This AD requires repetitive inspections of certain floor beams and revision of the maintenance or inspection program to include inspections of several areas of the wings. We are issuing this AD to detect and correct any cracking of the floor beam at FR 26 and several areas of the wings, which could lead to reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2011-24-05 for certain Airbus Model A330-201, -202, -203, -223, -243, -301, -302, - 303, -321, -322, -323, -341, -342, and -343 airplanes, and Model A340- 200 and -300 series airplanes. AD 2011-24-05 required repetitive inspections for cracking of the hole(s) of the horizontal flange of the keel beam, and repair if necessary. This new AD requires changing the inspection compliance times, and, for certain airplanes, adding a one- time ultrasonic inspection for cracking at a certain fastener hole. This new AD also provides optional terminating action for the repetitive inspections. This AD was prompted by a determination that the rototest inspection and applicable corrective actions of a certain fastener hole were inadvertently omitted from the requirements in AD 2011-24-05. We are issuing this AD to detect and correct cracking of the fastener holes, which could result in rupture of the keel beam, and consequent reduced structural integrity of the airplane.
Use of Spectrum Bands Above 24 GHz for Mobile Radio Services
In this document, the Federal Communications Commission (Commission or FCC) have identified specific spectrum bands above 24 GHz that appear to be suitable for mobile service, and we seek comment on proposed service rules that would authorize mobile and other operations in those bands. This development of service rules for mobile use of the millimeter wave (mmW) bands occurs in the context of our efforts to develop a regulatory framework that will help facilitate so- called Fifth Generation (5G) mobile services.
