<p>We might&#39;ve stumbled onto the real reason Donald Trump is running for president: He needs a private plane that&#39;s actually registered to fly.</p><p>The Federal Aviation Administration&nbsp;<a href="http://www.nytimes.com/2016/04/20/nyregion/donald-trumps-jet-a-regular-on-the-campaign-trail-is-not-registered-to-fly.html" target="_blank">confirmed to The New York Times</a>&nbsp;that the registration on one of Trumps planes&nbsp;<a href="http://registry.faa.gov/aircraftinquiry/NNum_Results.aspx?NNumbertxt=725DT" target="_blank">lapsed in January</a>&nbsp;and has yet to be renewed.</p><p>Trumps plane, a Cessna 750, reportedly made several flights on the campaign trail.</p><p>Trump&#39;s company, which registered the plane, got a warning in December from the FAA to renew the registration. The plane could be grounded until its registration issue is fixed.</p><p>Flying an unregistered plane could even result in a&nbsp;<a href="http://registry.faa.gov/aircraftinquiry/NNum_Results.aspx?NNumbertxt=725DT" target="_blank">six-figure fine</a>&nbsp;for the planes owner and up to three years in jail, though thats not likely.</p><p>Trump spokeswoman Hope Hicks says the plane&#39;s registration process is almost done, but the FAA says it hasn&#39;t received any paperwork for the Cessna.</p><p>Even if the Cessna is grounded, Trump wont have any trouble getting around. He still has a Boeing 757 and three helicopters.</p><p><i>This video includes clips from&nbsp;</i><i><a href="https://www.youtube.com/watch?v=aj_IsiMA4G4" target="_blank">CNN</a></i><i>,&nbsp;</i><i><a href="https://www.youtube.com/watch?v=v9L-prXogME" target="_blank">Fox Business</a></i><i>&nbsp;and&nbsp;</i><i><a href="https://www.youtube.com/watch?v=FpkDL3G7AoY" target="_blank">Donald J.
