PHOENIX (AP) - Four small airports in Arizona are on the Federal Aviation Administration's list for potential control tower closings under the automatic budget cuts that took effect this month.
The four are Glendale Municipal Airport, Phoenix Goodyear Airport, Laughlin/Bullhead International Airport in Bullhead City and Ryan Field in Tucson.
The FAA says they're among 238 small airports under consideration nationwide with low traffic volumes and control towers operated by contractors.
The FAA is scheduled to decide by March 18 on closing about 170 of the towers.
If they close, the FAA says the airports will remain open but pilots would be responsible for their own safety by talking to each other instead of the tower.
The FAA has to cut $600 million under the automatic budget cuts that took effect March 1.
