Establish Class E Airspace; Spencer, IA

This action establishes Class E surface area airspace at Spencer, IA, to accommodate Part 135 air carrier operations at Spencer Municipal Airport. Additional controlled airspace extending upward from the surface is needed to contain these aircraft executing instrument approach procedures. The intended effect of this proposal is to provide segregation of aircraft operating under Instrument Flight Rules (IFR) from other aircraft operating under Visual Flight Rules (VFR). Minor editorial revisions have been made to this final rule. After careful review of all available information related to the subject presented above, the FAA has determined that air safety and the public interest require the adoption of the rule as proposed except for minor editorial corrections. The FAA has determined that these minor changes will not change the meaning of the action and will not add any additional burden on the public than was already proposed.
