January 13, 2016 – Federal Register Recent Federal Regulation Documents

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.

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.

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.

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.

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.
