Gardner said the FAA's permits to fly in Colorado's air space are important to his state's rural areas.
"My district in particular is over 31,000 square miles, and due to the lack of a large scale airport, small planes provide a vital service in personal transportation and are used for business purposes such as the spraying of fields by agricultural aircraft," he said.
Gardner said in a statement Friday that he was requesting the audit because "this type of laziness and disregard from a government agency is unacceptable.
“My office has been trying to reach officials at FAA’s regional office and representatives in Washington D.C. to address a pressing economic matter that affects the state of Colorado," Gardner said. "Every day they ignore us businesses are losing money and the state is losing revenue.”
The FAA said Friday afternoon that it was working "in good faith" to answer Gardner's requests.
"The Federal Aviation Administration is aware of the applications and has been working in good faith with Congressman Gardner’s office over the past several months to address questions about the operator certification process," the agency said in a statement. "The FAA will continue to work closely with the congressman and his constituents to address any ongoing questions as they move through the certification process."
