The jet rolled seconds after takeoff before crashing at Bangor International Airport in January, killing six people, according to the report.

HOUSTON — The National Transportation Safety Board released its first report on the Jan. 25 crash that killed six people shortly after the aircraft took off at the Bangor International Airport.

Federal investigators are focusing on the time between deicing and liftoff. Anti-icing application began at 6:27:43 p.m. Central Time, and the jet lifted off at 6:43:57 p.m., with about 16 minutes elapsing. Under the federal guidelines, the maximum time between deicing and liftoff is 9 minutes.

The Bombardier Challenger 650 was operated by Houston law firm Arnold & Itkin LLP. Flight records show the plane originated from Hobby Airport in Houston, landed in Bangor, and was scheduled to continue to an airport near Paris, France.

The victims were pilot Jacob Hosmer, co-founder of Go Beyond Luxury Tara Arnold, sommelier Shelby Kuyawa, chef Nick Mastrascusa, event designer Shawna Collins and Jorden Reidel.

Investigators found no mechanical failures. Both engines were running at full power when the flight data recorder stopped recording.

The plane came to rest upside down in a grassy area off the runway and caught fire. Bangor International Airport was closed for several days.

The NTSB’s investigation remains ongoing. A final report with a probable cause determination is not expected until next year.
