GOP frontrunner Donald Trump’s plane isn’t registered with the Federal Aviation Administration, according to a recent New York Times report.

“Records kept with the Federal Aviation Administration show the aircraft’s registration lapsed on Jan. 31. Laura J. Brown, a spokeswoman for the Federal Aviation Administration, confirmed that the plane’s registration was not in good standing and said the owner had not renewed it,” reported New York Times‘ Susanne Craig.

The F.A.A. could also fine or assess other penalties against the owner, the operator or both; Mr. Trump owns the plane through a limited liability company. Though it is unlikely that the agency would seek the maximum penalty, flying with no registration could result in a civil penalty of up to $27,500, a criminal fine of up to $250,000 and imprisonment for up to three years, it said.

Trump’s spokesperson Hope Hicks did not comment further on the status of the pending renewal of the registration.
