A Ruskin postal carrier who flew a gyrocopter through some of America’s most restricted airspace before landing outside the U.S. Capitol earlier this year will plead guilty to a felony in connection with the incident, his lawyer says.

Attorney Mark Goldstone said in an email Thursday that his client Douglas Hughes is expected to plead guilty to operating a gyrocopter without a license, a felony, on Nov. 20 in federal court in Washington.

Goldstone says Hughes faces three years in prison, but the government and Hughes’ defense lawyer agreed that sentencing guidelines don’t apply.

Hughes was working as a U.S. Postal Service carrier in Ruskin when he flew the gyrocopter, painted like a U.S. Mail carrier, through highly restricted air space to the Capitol building April 15. He was dressed in his postman uniform and carried hundreds of letters, one for each member of Congress, outlining his grievances with campaign finance and lobbying practices.

Hughes had earlier turned down a plea bargain that would have carried a 10-month prison sentence, the second deal he rejected. He faces two felony and four misdemeanor charges, to which he had pleaded not guilty: operating as an airman without an airman’s certificate and violating aircraft registration requirements, and well three counts of violating national defense airspace and one of operating a vehicle falsely labeled as a postal carrier.
