Direct final rule; request for comments.


Mapleton Municipal Airport has been renamed James G. Whiting Memorial Field. A review of controlled airspace for Mapleton, IA indicates it does not comply with the criteria for 700 feet Above Ground Level (AGL) airspace required for diverse departures.

This action replaces “Mapleton Municipal Airport” in the legal description of Mapleton, IA Class E airspace area with “James G. Whiting Memorial Field.” It also enlarges the area to provide adequate protection for diverse departures and brings the legal description into compliance with FAA Orders.

This amendment to 14 CFR 71 modifies the Class E airspace area extending upward from 700 feet above the surface at Mapleton, IA. It replaces “Mapleton Municipal Airport,” the former name of the airport, with “James G. Whiting Memorial field,” the new name of the airport, in the legal description. A review of controlled airspace at Mapleton, IA indicates 700 feet Above Ground Level (AGL) airspace required for diverse departures, as specified in FAA Order 7400.2E, Procedures for Handling Airspace Matters, for James G. Whiting Memorial Field does not comply with the Order. The criteria in FAA Order 7400.2E for an aircraft to reach 1200 feet AGL is based on a standard climb gradient of 200 feet per mile plus the distance from the Airport Reference Point (ARP) to the end of the outermost runway. Any fractional part of a mile is converted to the next higher tenth of a mile. The area is enlarged to conform to the criteria in FAA Order 7400.2E. This action also modifies the northeast extension of the Mapleton, IA Class E airspace area by defining it with the 030° bearing from the Mapleton NDB versus the current 032° bearing. It brings the legal description of this airspace area into compliance with FAA Order 7400.2E. The area will be depicted on appropriate aeronautical charts. Class E airspace areas extending upward from 700 feet or more above the surface of the earth are published in paragraph 6005 of FAA Order 7400.9L, dated September 2, 2003, and effective September 16, 2003, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this document will be published subsequently in the Order.

The Direct Final Rule Procedure

The FAA anticipates that this regulation will not result in adverse or negative comment and, therefore, is issuing it as a direct final rule. Previous actions of this nature have not been controversial and have not resulted in adverse comments or objections. Unless a written adverse or negative comment, or a written notice of intent to submit an adverse or negative comment is received within the comment period, the regulation will become effective on the date specified above. After the close of the comment period, the FAA will publish a document in the Federal Register indicating that no adverse or negative comments were received and confirming the date on which the final rule will become effective. If the FAA does receive, within the comment period, an adverse or negative comment, or written notice of intent to submit such a comment, a document withdrawing the direct final rule will be published in the Federal Register and a notice of proposed rulemaking may be published with a new comment period.

Agency Findings
