Federal Aviation Administration September 2017 – Federal Register Recent Federal Regulation Documents

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

We are adopting a new airworthiness directive (AD) for all Airbus Model A350-941 airplanes. This AD requires repetitive on-ground power cycles to reset the internal timer. This AD was prompted by the in-service loss of communication between some avionics systems and the avionics network. We are issuing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2016-11-20 for certain B/E Aerospace protective breathing equipment (PBE) that is installed on airplanes. AD 2016-11-20 required replacing part number (P/N) 119003-11 PBE units. Since we issued AD 2016-11-20, we received a report that PBE units, P/N 119003-21, within a certain serial number range are made with candle tube material determined to have a low yield strength and may be volatile upon use or disposal. This AD retains the actions required in AD 2016-11-20 and requires inspecting and replacing P/N 119003-11 and 119003-21 PBE units. We are issuing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2015-22-51 for Agusta S.p.A. (Agusta) Model A109A and A109A II helicopters. AD 2015- 22-51 required pre-flight checking and inspecting each main rotor blade (blade) for a crack and replacing any cracked blade. This new AD removes the check and requires inspecting each blade more frequently. This AD is prompted by a crack that was not detected during any of the pre-flight checks. The actions of this AD are intended to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2015-02-22 for certain Rolls-Royce Corporation (RRC) model 250 turboprop and turboshaft engines. AD 2015-02-22 required repetitive visual inspections and fluorescent-penetrant inspection (FPIs) on certain 3rd- stage and 4th-stage turbine wheels for cracks in the turbine wheel blades. This AD requires repetitive visual inspections and FPIs of 3rd- stage turbine wheels while removing from service 4th-stage turbine wheels. We are also revising the applicability to remove all RRC turboprop engines and add additional turboshaft engines. This AD was prompted by our finding that it is necessary to remove the 4th-stage wheels at the next inspection. We are issuing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF6-80A, CF6-80A1, CF6-80A2, CF6- 80A3, CF6-80C2A1, CF6-80C2A2, CF6-80C2A3, CF6-80C2A5, CF6-80C2A5F, CF6- 80C2A8, CF6-80C2B1, CF6-80C2B1F, CF6-80C2B1F1, CF6-80C2B1F2, CF6- 80C2B2, CF6-80C2B2F, CF6-80C2B3F, CF6-80C2B4, CF6-80C2B4F, CF6-80C2B5F, CF6-80C2B6, CF6-80C2B6F, CF6-80C2B6FA, CF6-80C2B7F, CF6-80C2B8F, CF6- 80C2D1F, CF6-80C2L1F, and CF6-80C2K1F turbofan engines. This proposed AD was prompted by an uncontained failure of a high-pressure turbine (HPT) stage 2 disk. This proposed AD would require ultrasonic inspection (UI) of HPT stage 1 and 2 disks. We are proposing this AD to address the unsafe condition on these products.

The FAA is considering a proposal to change 3.44 acres of airport land from aeronautical use to non-aeronautical use and to authorize the sale of airport property located at Willow Run Airport, Detroit, Michigan. The aforementioned land is not needed for aeronautical use. The property is located in the southwest corner of the airport. It is outside of the airport operations area and is currently used as a Hazardous Waste Landfill. In 1996 the Federal Aviation Administration released 13.34 acres on this site to accommodate the Landfill. This proposal will release the remainder of the site. The proposed use will remain as a Hazardous Waste Landfill.

This notice announces the availability of and requests comments on the proposed design criteria for the Alexander Schleicher GmbH & Co. models ASG 32 & ASG 32 Mi gliders. The administrator finds the proposed design criteria, which make up the certification basis for the ASG 32 & ASG 32 Mi gliders, acceptable.These final design criteria will be published in the Federal Register.

We are adopting a new airworthiness directive (AD) for certain Diamond Aircraft Industries GmbH Models DA 42, DA 42 M-NG, and DA 42 NG airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as crack formation on the flap bell crank, which could cause the flap bell crank to fail. We are issuing this AD to require actions to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2012-23-09, which applied to all Embraer S.A. Model ERJ 190-100 STD, -100 LR, and - 100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. AD 2012-23-09 required revising the maintenance program to incorporate certain modifications in airworthiness limitations. This new AD requires revising the maintenance or inspection program to incorporate certain modifications in the airworthiness limitations to include new inspection tasks and their respective thresholds and intervals. This AD was prompted by our determination that more restrictive maintenance requirements and airworthiness limitations are necessary. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200, A330-200 Freighter, A330-300, A340-500, and A340-600 series airplanes; and A340-313 airplanes. This AD was prompted by the discovery of Tartaric Sulfuric Anodizing (TSA)/Chromic Acid Anodizing (CAA) surface treatment in certain bulk cargo door frame holes of certain airplanes. This AD requires inspection of the fuselage bulk cargo door frames at specific locations, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain General Electric Company (GE) CF34-8 model turbofan engines. This AD was prompted by analysis that resulted in the reduction of the life of the affected fan blades. This AD requires inspections of the affected fan blades until their removal. We are issuing this AD to address the unsafe condition on these products.
