The FAA is issuing this notice to advise the public that a meeting of the Federal Aviation Administration Air Traffic Procedures Advisory Committee (ATPAC) will be held to review present air traffic control procedures and practices for standardization, revision, clarification, and upgrading of terminology and procedures.
Proposed Modification of Class B Airspace; Las Vegas, NV
This action reopens the comment period for an NPRM that was published on October 26, 2012. In that document, the FAA proposed to modify the Las Vegas, NV, Class B airspace area to ensure the containment of large turbine-powered aircraft within Class B airspace.
Airworthiness Directives; CFM International, S.A. Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for certain CFM International, S. A. (CFM) model CFM56-5 and CFM56-5B series turbofan engines. This proposed AD was prompted by corrosion of the delta P valve in the hydromechanical unit (HMU) caused by contaminants in type TS-1 fuel. This proposed AD would require cleaning, inspection and repair of affected HMUs. We are proposing this AD to prevent seizure of the HMU, leading to failure of one or more engines and damage to the airplane.
Airworthiness Directives; Lycoming Engines and Continental Motors, Inc. Reciprocating Engines
The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to Lycoming Engines TSIO-540-AK1A, and Continental Motors, Inc. TSIO-360-MB, TSIO-360-SB, and TSIO-360-RB reciprocating engines, with certain Hartzell Engine Technologies (HET) turbochargers, model TA0411, part number 466642- 0001; 466642-0002; 466642-0006; 466642-9001; 466642-9002; or 466642- 9006, or with certain HET model TA0411 turbochargers overhauled or repaired since August 29, 2012. The Summary paragraph and the Applicability paragraph list an incorrect engine model for Lycoming Engines. This document corrects those errors. In all other respects, the original document remains the same.
