Federal Aviation Administration July 7, 2015 – Federal Register Recent Federal Regulation Documents

This notice announces the availability of and request comments on the proposed authorization of Alaska Fixed Wing External Loads (FWEL) as a new restricted category special purpose operation, pursuant to Title 14 of the Code of Federal Regulations (14 CFR) 21.25(b)(7), for operations within the State of Alaska.

This notice announces the Federal Aviation Administration's (FAA) intent to cancel AC 20-159. This cancellation will result in no new approval of technical standard order authorizations (TSOA) for an ``incomplete system'' issued for Technical Standard Order (TSO) C-165, Electronic Map Display Equipment for Graphical Depiction of Aircraft Position. Therefore, the guidance contained in AC 20-159 allowing applicants to obtain a design and production approval using the software and database for an airport moving map display (AMMD) intended for use on a Class 2 electronic flight bag (EFB) for ground operations, will no longer be available. FAA AC 120-76C, Guidelines for the Certification, Airworthiness, and Operational Use of Electronic Flight Bags, dated May 9, 2014, replaces AC 20-159 and provides guidance for applicants seeking authorization to display an own-ship symbol limited to the airport surface as a Type B application for use on any EFB.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and Model CL-600-2D24 (Regional Jet Series 900) airplanes. This proposed AD was prompted by a report indicating that some operators have inadvertently removed the existing insulation blankets from the upper wing box area. This proposed AD would require inspecting for and replacing missing insulation blankets in the upper wing box area. We are proposing this AD to detect and replace missing insulation blankets from the upper wing box area, which could result in inadequate thermal protection to prevent fuel ignition in the event of an undetected bleed air leak due to a cracked or ruptured bleed-air duct.

We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-46-350P and PA-46-500TP airplanes. This AD requires installing cable ties around the cabin altitude encoder and the supporting structure, adding thread-locking compound to the threads of the existing single fastener; and repetitively inspecting the cable ties and the fastener to ensure security and proper condition. This AD was prompted by a report that a cabin altitude encoder came free from its mounting bracket, which interfered with motion of the elevator flight control. We are issuing this AD to correct the unsafe condition on these products.
