PORTLAND, Maine (AP) — The business jet that crashed during takeoff as a snowstorm moved in and visibility diminished in Maine Sunday night, killing at least a half dozen people, is a model with a history of crashes caused by ice on the wings.

The Bombardier Challenger 600 flipped over and burned on takeoff at Bangor International Airport around 7:45 p.m. Sunday night as the nation’s massive winter storm was beginning to reach the area.

The airport said Monday afternoon that there were six people aboard, according to the flight manifest, and all of them died. Earlier in the day, the Federal Aviation Administration said seven people died and one member of the crew survived, but a spokesman said those numbers were preliminary and subject to change. The airport said no one was taken to a hospital.

Snowfall was heavy elsewhere at the time of the crash, but accumulation had just started in Bangor. Other planes had been taking off safely. But about half an hour before the crash, the pilot of a Florida-bound Allegiant plane radioed the tower to abort his takeoff.

“One, our deice fluid has failed and two, I don’t think the visibility is good enough for us to go, so we’re going to have to taxi back to the gate here,” the Allegiant pilot radioed. The controller responded by saying he was just getting ready to warn the pilot that visibility had dropped to about three-quarters of a mile.

At about the same time, the pilot of the Bombardier had taxied over to the deicing pad and was radioing in a request to get his plane’s wings and tail treated, according to audio posted by www.LiveATC.net. The plane remained at the deicing pad for about 20 minutes before taxiing to the runway.

The Bombardier Challenger 600 model “has a history of problems with icing on takeoff” that has caused previous crashes, aviation safety consultant Jeff Guzzetti said. Even a little bit of ice on the wings can cause serious problems, so the passenger jet would have needed deicing before takeoff, the former federal crash investigator said.

The identities of those onboard won’t be released publicly until they can be confirmed, officials said.

The jet was registered to a corporation that shares the same address in Houston, Texas as the personal injury law firm Arnold and Itkin Trial Lawyers, and one of the law firm’s founding partners is listed as the registered agent for the company that owns the plane.

The international airport in Bangor, about 200 miles north of Boston, is one of the closest in the U.S. to Europe and is often used to refuel private jets flying overseas.

The airport shut down after the crash and will remain closed at least until Wednesday so the FAA and National Transportation Safety Board investigators can examine and remove the wreckage.

No cause has been determined. The NTSB said preliminary information shows the plane crashed upon departure and experienced a post-crash fire, but that it would have no further statement until after investigators arrive in a day or two.
