Amendment of Class D and Class E Airspace; Elmira, NY
This action amends Class D and E airspace at Elmira, NY, as the ERINN Outer Marker (OM) has been decommissioned requiring airspace reconfiguration at Elmira/Corning Regional Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport. This action also updates the geographic coordinates of the airport, and eliminates the Notice to Airmen (NOTAM) part-time status of the Class E airspace designated as an extension to a Class D surface area. Also, the FAA found the Class E airspace designated as an extension to a class D surface area description was inaccurate. This action corrects the error.
Establishment of Class E Airspace; Kill Devil Hills, NC
This action establishes Class E airspace at Kill Devil Hills, NC, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) serving First Flight Airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at the airport.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We are superseding airworthiness directive (AD) 2012-04-01 for all Rolls-Royce plc (RR) RB211-Trent 800 model turbofan engines. AD 2012-04-01 required removal from service of certain critical engine rotating parts based on reduced life limits. This AD makes additional revisions to the life limits of certain critical engine rotating parts. This AD was prompted by RR further revising the life limits of certain critical engine rotating parts. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We are superseding airworthiness directive (AD) 2017-01-01 for all Rolls-Royce plc (RR) RB211-Trent 970-84, RB211-Trent 970B-84, RB211-Trent 972-84, RB211-Trent 972B-84, RB211-Trent 977-84, RB211- Trent 977B-84, and RB211-Trent 980-84 turbofan engines. AD 2017-01-01 required inspections of the low-pressure turbine (LPT) exhaust case and support assembly or tail bearing housing (TBH) to detect cracks or damage. This AD corrects references to certain service bulletins in the compliance section of AD 2017-01-01. This AD was prompted by reports that references to service bulletins in AD 2017-01-01 are incorrect. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 series airplanes; Model A300 B4-600, B4-600R, and F4- 600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Model A310 series airplanes. This AD was prompted by a report indicating that during inspections to detect corrosion of the bulk cargo doors, several cracks were discovered. This AD requires inspections of the bulk cargo door frame to identify any structural repairs and cracking, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
Hazardous Materials: Use of DOT Specification 39 Cylinders for Liquefied Flammable Compressed Gas
PHMSA is issuing this revised safety advisory notice to address concerns of offerors and users of DOT Specification 39 (DOT-39) cylinders that exceed 75 cubic inches (in\3\) (1.23 L) and to provide clarification of the initial safety advisory notice we issued on this subject on December 13, 2016 (Notice No. 2016-14). DOT-39 cylinders exceeding 75 in\3\ (1.23 L) should not contain liquefied flammable compressed cyclopropane, ethane, or ethylene, or liquefied petroleum gases. PHMSA advises against the filling or transporting of these gases in DOT-39 cylinders when the cylinder's internal volume exceeds 75 in\3\ (1.23 L).
