A man who became drunk and disruptive on a February All Nippon Airways flight from Japan, causing the jet to be diverted to Anchorage, has made a guilty plea in the federal case against him.

U.S. Attorney Karen Loeffler’s office says Friday that Nobuya Michael Ochinero, 38, pleaded guilty to one count of interfering with a flight crew in the Feb. 10 incident.

According to a charging document in the case, Ochinero was on several medications when he boarded ANA Flight 10 from Tokyo’s Narita International Airport to New York City’s John F. Kennedy International Airport.

Ochinero told investigators he drank four shots of gin and two beers on board the flight, with passengers and flight attendants saying he pushed and berated them after he was refused further alcohol. He was eventually strapped to his chair until the plane landed at Ted Stevens Anchorage International Airport at about 12:40 a.m. Monday. Law enforcement officers took Ochinero into custody and he was held at the Anchorage Jail, where his blood-alcohol content was measured at 0.137.

Assistant U.S. Attorney Stephanie Courter, who prosecuted the case against Ochinero, says prosecutors didn’t drop any charges against Ochinero in exchange for his plea. While he has agreed to pay restitution to ANA for its costs in the incident, with a maximum possible sentence of 20 years in prison and a $250,000 fine, his final sentence has yet to be decided by a judge.

“We plan to ask for a fairly extensive period of probation, giving (Ochinero) time to pay that restitution,” Courter said. “Of course, our recommendation is our recommendation and the judge can impose his own sentence.”

Ochinero’s sentencing date has been set for July 7.
