RTCA Government/Industry Air Traffic Management Advisory Committee
The FAA is issuing this notice to advise the public of a meeting of RTCA Government/Industry Air Traffic Management Advisory Committee.
Seventh Plenary Meeting, NextGen Mid-Term Implementation Task Force
The FAA is issuing this notice to advise the public of a meeting of the NextGen Mid-Term Implementation Task Force.
Proposed Amendment of Class E Airspace; Ankeny, IA
This action proposes to amend Class E airspace at Ankeny, IA. Cancellation of NDB approaches at Ankeny Regional Airport has made it necessary to reconfigure Class E airspace. Controlled airspace is necessary to accommodate Standard Instrument Approach Procedures (SIAPs) at Ankeny Regional Airport, Ankeny, IA. This action also would update the geographic coordinates of the airport to coincide with the FAA's National Aeronautical Charting Office. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) aircraft operations at Ankeny Regional Airport.
Special Conditions: Boeing Model 747-8/-8F Airplanes, Structural Design Requirements for Four-Post Main Landing Gear System
This action proposes special conditions for the Boeing Model 747-8/-8F airplane. This airplane will have novel or unusual design features associated with a four-post main landing gear system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Ninth Meeting, RTCA Special Committee 216: Aeronautical System Security
The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 216: Aeronautical Systems Security.
Sixth Plenary Meeting, NextGen Mid-Term Implementation Task Force
The FAA is issuing this notice to advise the public of a meeting of the NextGen Mid-Term Implementation Task Force.
Proposed Amendment of Class E Airspace; Mansfield, OH
This action proposes to amend Class E airspace at Mansfield, OH. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Mansfield/Lahm Regional Airport, Mansfield, OH. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) aircraft operations at Mansfield/Lahm Regional Airport. This action also would update the airport name to Mansfield/Lahm Regional Airport and update the geographic coordinates of Shelby Community Airport and Willard Airport.
Airworthiness Directives; Dassault Model Falcon 2000EX Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Airworthiness Directives; Rolls-Royce plc RB211 Trent 800 Series Turbofan Engines
The FAA proposes to supersede an existing airworthiness directive (AD) for Rolls-Royce plc RB211 Trent 875-17, Trent 877-17, Trent 884-17, Trent 892-17, Trent 892B-17, and Trent 895-17 turbofan engines with high pressure (HP) compressor rotor rear stage 5 and 6 discs and cone shafts, part numbers (P/Ns) FK25230 and FK27899 installed. This proposed AD would require removing these parts at new reduced cycle limits. This proposed AD results from Rolls-Royce plc reducing the lives of these parts and changing the life calculating method to use ``Standard Duty Cycles'' with ``Multiple Flight Profile Monitoring'' and ``Flight Cycles'' with ``Heavy Flight Profile Monitoring''. We are proposing this AD to prevent stage 5 and 6 disc crack initiation and propagation that might lead to uncontained disc failure and damage to the airplane.
Airworthiness Directives; Turbomeca S.A. Arriel 2B and 2B1 Turboshaft Engines
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:
Airworthiness Directives; EADS-PZL “Warszawa-Okęcie” S.A. Model PZL-104 WILGA 80 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 the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; Sikorsky Aircraft Corporation Model S-92A Helicopters
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2009-07-53, which was sent previously to all known U.S. owners and operators of Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters by individual letters. This amendment is prompted by the failure of 2 main gearbox filter bowl assembly studs (studs) that were found broken during a fatal accident investigation in Canada. Prior to the accident, the manufacturer was investigating a July 2008 incident that also involved broken studs. In both cases, the broken studs resulted in rapid loss of oil. The failures have been tied to fretting and galling of the original titanium studs; therefore, this AD requires removing all titanium studs and replacing them with steel studs. The actions specified by this AD are intended to prevent failure of a stud, which could result in rapid loss of oil, failure of the main gearbox, and subsequent loss of control of the helicopter.
