Justin Bieber got a big break ... despite the fact that he and his buds turned a private jet into a hotbox during a flight to the Super Bowl ... the FAA has cleared the singer after an investigation.
As TMZ previously reported ... the plane was stopped after it arrived at Teterboro airport in New Jersey because of a strong odor of pot coming from the plane.
Nonetheless the FAA determined neither Biebs nor any of the other passengers interfered with the flight crew ... so case closed.
That doesn't mean Bieber won't be stopped by U.S. Customs the next time he flies to the U.S. from another country. Because of his criminal cases ... we're told Biebs will very like be grilled the way he was during that Super Bowl trip ... grilled for hours before being allowed to leave.
