Airworthiness Directives; Rolls-Royce plc RB211 Trent 700 Series Turbofan Engines
The FAA proposes to supersede an existing airworthiness directive (AD) for Rolls-Royce plc (RR) RB211 Trent 700 series turbofan engines. That AD currently requires initial and repetitive borescope inspections of the high pressure-and-intermediate pressure (HP-IP) turbine internal and external oil vent tubes for coking and carbon buildup, and cleaning or replacing the vent tubes if necessary. This proposed AD would require the same actions, but would add additional inspections of the vent flow restrictor. This proposed AD results from further analysis that the cleaning of the vent tubes required by AD 2007-02-05 could lead to loosened carbon fragments, causing a blockage downstream in the vent flow restrictor. We are proposing this AD to prevent internal oil fires due to coking and carbon buildup that could cause uncontained engine failure and damage to the airplane.
Airworthiness Directives; International Aero Engines AG (IAE) V2500-A1, V2527E-A5, V2530-A5, and V2528-D5 Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for International Aero Engines AG (IAE) V2500-A1, V2527E-A5, V2530-A5, and V2528-D5 turbofan engines. This AD requires reducing the published life limit of certain high-pressure compressor (HPC) stage 9-12 disc assemblies. This AD also removes from service those HPC stage 9-12 disc assemblies using a drawdown schedule. This AD results from IAE updating the low-cycle-fatigue (LCF) life analysis for certain HPC stage 9-12 disc assemblies. We are issuing this AD to prevent an uncontained failure of the HPC stage 9-12 disc assembly, resulting in an in-flight engine shutdown and possible damage to the airplane.
Proposed Establishment of Area Navigation Route Q-37; Texas
This action proposes to establish a high altitude area navigation (RNAV) route, designated Q-37, extending between the Pueblo, CO, very high frequency omnidirectional range/tactical air navigation (VORTAC) navigation aid and the Fort Stockton, TX, VORTAC. The new route would provide pilots and air traffic controllers with an efficient alternative route around potentially constrained airspace during convective weather events in west Texas.
Notice of Intent To Request Reinstatement From the Office of Management and Budget of an Expired Information Collection Activity, Request for Comments; Flight Attendant Duty/Rest/Fatigue Field Study
The FAA invites public comments about our intention to request the Office of Management and Budget (OMB) to reinstate an expired information collection. In response to a Congressional directive to conduct a flight attendant fatigue study, FAA's Civil Aerospace Medical Institute, has initiated a comprehensive analysis of fatigue in flight attendants across a range of operational conditions.
Establishment of Class E Airspace; Noorvik, AK
This action establishes Class E airspace at Noorvik, AK to provide adequate controlled airspace to contain aircraft executing Standard Instrument Approach Procedures (SIAPs). Two SIAPs are being developed for the Robert (Bob) Curtis Memorial Airport at Noorvik, AK. Additionally, one textual Obstacle Departure Procedure (ODP) is being developed. This action establishes Class E airspace upward from 700 feet (ft.) above the surface at Robert (Bob) Curtis Memorial Airport, Noorvik, AK.
Amendment of Federal Airways V-163 and V-358 in the Lampasas, TX, Area
This action amends the legal descriptions of two Federal airways that have ``Lampasas, TX, very high frequency omnidirectional range/tactical air navigation (VORTAC)'' included as part of their route structure. Currently, the Lampasas VORTAC and the Lampasas Airport share the same location name and identifier (LZZ). To eliminate confusion and potential flight safety issues, the ``Lampasas VORTAC'' (LZZ) will be renamed the ``Gooch Springs VORTAC'' (AGJ). All airways with Lampasas [VORTAC] included in their legal descriptions will be amended, concurrent with the effective date of this final rule, to reflect the name change.
