Airworthiness Directives; Pratt & Whitney PW4000 Series Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain Pratt & Whitney PW4000 series turbofan engines. This proposed AD would require initial and repetitive borescope inspections (BSI) or fluorescent penetrant inspections (FPI) for cracks in the anti-vortex tube (AVT) shelf slots on the 10th stage disk of the high- pressure compressor (HPC) drum rotor disk assembly. This proposed AD results from 47 reports received since 2007 of HPC 10th stage disks found cracked in the AVT shelf slots during shop visit inspections. We are proposing this AD to prevent failure of the HPC 10th stage disk, uncontained engine failure, and damage to the airplane.
IFR Altitudes; Miscellaneous Amendments
This document adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.
Notice of Intent To Request Approval From the Office of Management and Budget of a New Information Collection Activity, Request for Comments; AST Collection of Voluntary Lessons Learned From External Sources
The FAA invites public comments about our intention to request the Office of Management and Budget (OMB) to approve a new information collection. The FAA/AST will collect lessons learned from members of the commercial space industry in order to carry out the safety responsibilities in 49 U.S.C Chapter 701 Section 70103(c).
Establishment of Class E Airspace; Kemmerer, WY
This action will establish Class E airspace at Kemmerer, WY to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) at Kemmerer Municipal Airport. This will improve the safety and management of Instrument Flight Rules (IFR) operations at the airport.
