Chartered Jets arrive at Teterboro airport ahead of the Super Bowl. Justin Bieber (inset) is reportedly facing an FAA investigation of his flight.

Justin Bieber is facing an FAA investigation over his pot-smoking Super Bowl jet flight that sent pilots scrambling for oxygen masks because they feared heavy marijuana smoke might threaten the safety of the flight and jeopardize their licenses.

The investigation is being handled out of the Federal Aviation Administration’s Northeast regional office in Jamaica, N.Y., according to a source in Washington, D.C.

Bieber rented the private jet to fly himself and an entourage people, including his father, Jeremy Bieber from Toronto to Teterboro Airport, N.J. airport.

The airport, operated by the Port Authority of New York & New Jersey, is a major hub for private aircraft flying big wigs to New York City. John F. Kennedy Jr., made his fatal flight to Martha’s Vineyard from the airport in 1999.

The Super Bowl was played Feb. 2 at MetLife Stadium, East Rutherford, N.J., home of The New York Giants.

Although U.S. Customs and Border Protection officers cleared Bieber and his entourage to enter the United States after searching the plane for drugs, the FAA is responsible for enforcing flight regulations on commercial airlines and privately chartered commercial jets.

TheImproper reported on Feb. 5 that Bieber, his father and others on the plane many have committed multiple felonies while in flight, according to an examination of applicable federal regulations.

Some of the violations are felonies that carry up to a $25,000 fine on each count and 20 years in prison.

Bieber and his father allegedly refused a pilot’s repeated direct orders to stop smoking pot during the flight. It’s a clear violation of federal law to refuse a direct order from a pilot, who is responsible for the overall safety of the plane and passengers.

According to NBC and a separate report by CNN, however, the marijuana smoke was so thick, the pilots were force to wear their oxygen masks to avoid intoxication. The smoke could have impeded their ability to fly the aircraft safely.

The pilots were also reportedly concerned that they could test positive on a drug test and jeopardized their licenses according to NBC News.

Bieber and his father were so verbally abusive to a flight attendant, the pilot told her to stay close to the cockpit to avoid further contact with them, according to NBC.

It’s a violation of FAA regulations for a passenger to verbally abuse, threaten, intimidate or interfere with the duties of an aircraft crew member, according to according to The International Air Transport Association (IATA), a trade association representing the nation’s airlines.

The extent of the investigation and other details are unknown. A spokesman in the FAA’s Jamaica office did not return a call for comment.
