Bangor International Airport will remain closed until at least 9 a.m. on Thursday.
The airport has been closed since Sunday evening when a private jet crashed killing two crew members and four passengers.
Investigators from the Federal Aviation Administration and National Transportation Safety Board arrived in Bangor on Tuesday. A spokesperson for the airport said the NTSB, which investigates crashes, has asked that the crash scene be preserved.
The airport on Tuesday estimated that at least 35 domestic arrivals and 35 departures would be affected by the crash investigation and snowstorm by the time the airport reopens.
Passengers are encouraged to contact their airlines for information about their travel plans.
The business jet, a Bombardier Challenger 600 registered to principals of a Houston-area law firm, had stopped in Bangor to refuel on Sunday evening. It flipped over and caught fire as it was taking off again around 7:45 p.m.
Family and friends have since identified three of the victims, including Tara Arnold, Shawna Collins and pilot Jacob Hosmer.
The cause of the crash is not yet known, but the Challenger 600, which can carry a crew of two and nine passengers, is known to be particularly vulnerable to ice and snow. According to the airport, the plane received de-icing services while it was on the ground in Bangor.
