Trump campaign plane flying with expired registration
The Republican presidential candidate's airplane lost its registered status in January after failure to pay a $5 fee to the FAA.
The aircraft in violation is not Trump's Boeing 757, the renovated commercial jet that the billionaire sometimes uses as a backdrop for his rallies.
If the FAA learns that a registration has expired by the plane is still being flown, the agency typically sends a warning letter to the owner, according to aircraft operators who asked not to be named because they didn't want to be associated with the Trump case.
