Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767-200 and -300 series airplanes. This proposed AD would require repetitive inspections for cracking of the aft pressure bulkhead at station (STA) 1582, repair or replacement of any cracked bulkhead, and eventual replacement of the aft pressure bulkhead at STA 1582 with a new bulkhead. Accomplishing the replacement would terminate the repetitive inspections specified in this proposed AD. This proposed AD was prompted by reports of multiple site damage cracks in the radial web lap and tear strap splices of the aft pressure bulkhead at STA 1582 due to fatigue. We are proposing this AD to prevent fatigue cracking of the aft pressure bulkhead, which could result in rapid decompression of the airplane and possible damage or interference with the airplane control systems that penetrate the bulkhead, and consequent loss of controllability of the airplane.
Office of Commercial Space Transportation (AST); Notice of Availability and Request for Comment on the Draft Environmental Assessment (EA) for Issuing an Experimental Permit to SpaceX for Operation of the Grasshopper Vehicle at the McGregor Test Site, Texas
In accordance with the National Environmental Policy Act (NEPA) of 1969, 42 United States Code 4321-4347 (as amended), Council on Environmental Quality (CEQ) NEPA implementing regulations (40 Code of Federal Regulations [CFR] parts 1500-1508), and FAA Order 1050.1E, Change 1, the FAA is announcing the availability of and requesting comments on the Draft EA for Issuing an Experimental Permit to SpaceX for Operation of the Grasshopper Vehicle at the McGregor Test Site, Texas. The Draft EA was prepared in response to an application for an experimental permit from Space Exploration Technologies Corporation (SpaceX). Under the Proposed Action, the FAA would issue an experimental permit to SpaceX to conduct suborbital launches and landings of the Grasshopper Reusable Launch Vehicle (RLV) from the McGregor test site in McGregor, TX. The Grasshopper RLV is a vertical takeoff and vertical landing vehicle. The McGregor test site is located within the city limits of the City of McGregor, TX in Coryell and McLennan Counties, approximately 20 miles southwest of Waco, TX. The Draft EA addresses the potential environmental impacts of implementing the Proposed Action and the No Action Alternative of not issuing an experimental permit to SpaceX. The FAA has posted the Draft EA on the FAA/AST Web site at https:// www.faa.gov/about/officeorg/headquartersoffices/ast/. In addition, copies of the Draft EA were sent to persons and institutions on the distribution list (see Chapter 8 of the Draft EA). A paper copy of the Draft EA may be reviewed for comment during regular business hours at the following location: McGinley Memorial Library, 317 Main Street, McGregor, TX 76657.
Amendment of Class D and E Airspace and Revocation of Class E Airspace; Manassas, VA
This action amends Class D and Class E airspace areas and removes Class E airspace designated as an extension at Manassas Regional Airport/Harry P. Davis Field, Manassas, VA. A Standard Instrument Approach Procedure has been cancelled. Therefore modification to the airspace areas is required for the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport. This action also notes the name change of the airport.
Establishment of Class E Airspace; Lebanon, PA
This action establishes Class E airspace at Lebanon, PA, to accommodate new Standard Instrument Approach Procedures that have been developed for Keller Brothers Airport. This action also corrects a typographic error in the latitude coordinates of the airport. This action enhances the safety and management of Instrument Flight Rules (IFR) operations at the airport.
Establishment of Class E Airspace; Gordonsville, VA
This action establishes Class E Airspace at Gordonsville, VA, to accommodate the new Standard Instrument Approach Procedures serving Gordonsville Municipal Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.
