Federal Aviation Administration March 4, 2014 – Federal Register Recent Federal Regulation Documents

We are revising an earlier NPRM for DORNIER LUFTFAHRT GmbH Models Dornier 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212 airplanes that would supersede AD 2006-11-19. 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 chafed or damaged wiring on the flight deck overhead panels (5VE and 6VE). We are issuing this proposed AD to require actions to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2002-10-11, which applied to certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. AD 2002-10-11 required repetitive inspections for cracking and corrosion of the aft pressure bulkhead, and corrective actions if necessary; and, for certain airplanes, enlargement of frame chord drain holes, and repetitive inspections of the frame chord drain path for debris, and corrective actions if necessary. This new AD specifies a drain path inspection for all airplanes. For certain airplanes, this new AD reduces the repetitive inspection interval; and adds repetitive inspections of the frame chord drain path for obstructions and debris, and corrective actions if necessary. This AD was prompted by three reports of severe corrosion in the area affected by AD 2002-10-11. We are issuing this AD to detect and correct corrosion or cracking of the aft pressure bulkhead, which could result in loss of the aft pressure bulkhead web and stiffeners, and consequent rapid decompression of the airplane.

This action amends Class E Airspace at Macon, GA, as the Bay Creek Non-Directional Beacon (NDB) has been decommissioned and airspace reconfiguration is necessary for the safety and airspace management of Instrument Flight Rules (IFR) operations at Perry-Houston County Airport. This action also amends controlled airspace and updates the name and geographic coordinates of Macon Downtown Airport and amends controlled airspace for Middle Georgia Regional Airport.

This action amends Class E airspace at Philip, SD. Additional controlled airspace is necessary to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at Philip Airport. Geographic coordinates are also adjusted. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.

This action amends Class E airspace at Hampton, IA. Decommissioning of the Hampton non-directional beacon (NDB) at Hampton Municipal Airport has made reconfiguration necessary for standard instrument approach procedures and for the safety and management of Instrument Flight Rule (IFR) operations at the airport.

This action establishes Class E airspace at Mansfield, OH. A Class E surface area is necessary to accommodate military mission changes when the control tower is closed at Mansfield Lahm Regional Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.

This action amends Class E airspace at Hamilton, OH. Decommissioning of the Hamilton non-directional radio beacon (NDB) at Butler County Regional Airport has made reconfiguration necessary for standard instrument approach procedures and for the safety and management of Instrument Flight Rule (IFR) operations at the airport. The airport's name and geographic coordinates are also adjusted.

This action amends Class D airspace within the St. Paul, MN, area by updating the geographic coordinates for St. Paul Downtown Airport/Holman Field, and South St. Paul Municipal Airport-Richard E. Fleming Field. This action does not change the boundaries or operating requirements of the airspace.
