Flights in and out of Lasko Airport in western Michigan were canceled as authorities investigated the cause of a plane crash that killed at least four people and injured seven others.
A total of nine people were killed in the accident early Friday morning.
The National Transportation Safety Board (NTSB) said in a statement that it had identified four pieces of the Boeing 737-800 as the “primary cause of the crash.”
NTSB officials said the plane was traveling at “high speed” when it crashed.
A video posted to social media shows a large plume of black smoke rising from the fuselage and landing on the runway.
The plane went into a steep dive, and all four people on board were killed.
A passenger plane from an Alaska Airlines flight crashed during takeoff, killing at least seven people and injuring more than 50 others, the NTSB said.
It was not immediately clear how the crash happened.
The crash occurred at about 1:45 a.m. local time in the Laskoski International Airport, about 100 miles north of Detroit.
The NTSB, which investigates crashes, said it had received information about the plane going through a “high-speed descent” at about 300 mph (480 km/h).
The NTSBs preliminary investigation found the aircraft had a “low-level” fuel leak and that the “low level” was likely caused by a “small leak” from the aircraft’s electrical system.
NTSB investigators said they are looking into “the possible cause of any engine failure.”
