PORTLAND, Maine — 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 de-ice 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 crash victims have not been officially identified

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

FTA, NTSB investigators will examine the wreckage

The airport shut down after the crash and will remain closed at least until Wednesday so the

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.
