摘要
This action amends Class D airspace at the Medford, Portland- Hillsboro, and Salem Airports, Oregon. It will add information regarding hours of operation to the airspace description. Airspace reclassification, in effect as of September 16, 1993, has discontinued use of the term ``control zone,'' replacing it with the description ``Class D'' airspace. The Class D airspace is depicted on aeronautical charts for pilot reference.
