New York is not an open carry state, and its airports are definitely not open carry-on either.

Federal officials say a Florida man has been caught trying to go through security at an upstate New York airport with a loaded gun for the second time this month.

The man was arrested Wednesday at Syracuse Hancock International Airport after Transportation Security Administration officers spotted a loaded handgun in his carry-on bag. Officials say the same man was caught with a different loaded handgun on Nov. 6 at the airport in Ithaca.

Both times, he claimed he didn't know he had his gun with him.

Officials say TSA has authority to assess penalties up to $13,000 for weapons violations.

The man's name wasn't released by TSA or Syracuse police.
