Airworthiness Directives; Honeywell International Inc. ATF3-6 and ATF3-6A Series Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for Honeywell International Inc. ATF3-6 and ATF3-6A series turbofan engines equipped with a certain part number (P/N) low pressure compressor (LPC) aft shaft. This proposed AD would require removing from service those LPC aft shafts and installing a serviceable LPC aft shaft. This proposed AD results from reports of eight LPC aft shafts found cracked during fluorescent penetrant inspection (FPI). We are proposing this AD to prevent uncoupling and overspeed of the low pressure turbine, which could result in uncontained engine failure and damage to the airplane.
Airworthiness Directives; DG Flugzeugbau GmbH Model DG-500 Elan Series, DG-500M, and DG-500MB Gliders
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Petitions for Exemption; Summary of Petitions Received
This notice contains a summary of certain petitions seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of any petition or its final disposition.
Airworthiness Directives; Alpha Aviation Design Limited (Type Certificate No. A48EU Previously Held by Apex Aircraft and Avions Pierre Robin) Model R2160 Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. 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:
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
This Rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures 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.
Automatic Dependent Surveillance-Broadcast (ADS-B) Out Performance Requirements To Support Air Traffic Control (ATC) Service
This notice proposes performance requirements for certain avionics equipment on aircraft operating in specified classes of airspace within the United States National Airspace System. The proposed rule would facilitate the use of Automatic Dependent Surveillance-Broadcast (ADS-B) for aircraft surveillance by Federal Aviation Administration and Department of Defense air traffic controllers to accommodate the expected increase in demand for air transportation. In addition to accommodating the anticipated increase in operations, this proposal, if adopted, would provide aircraft operators with a platform for additional flight applications and services.
