The National Transportation Safety Board (NTSB) announced that it is investigating an engine fire on a United Airlines Boeing 737 MAX 9 after the plane landed at Newark-Liberty Airport, New Jersey.
The NTSB released the investigation Friday, when it issued a preliminary report on the June 28 incident in which no one was injured.
One of the plane’s two engines caught fire after it completed a flight from Fort Lauderdale, Florida, carrying 179 passengers and five crew members.

The pilots stated that they became aware of a fire warning indicator on the left engine while en route to the airport gate. They shut down the engine and discharged a fire retardant, and the warning indicator went out, according to the NTSB.
“No smoke or fire was coming from the engine, but the aircraft was towed to the gate, where maintenance crews saw signs of fuel leakage from the engine and heat damage to the interior of the canopy,” the NTSB said.
Federal Aviation Administration (FAA) records indicate that the aircraft was built in late 2020.
The NTSB reported that the investigation involves representatives from Boeing, engine manufacturer CFM International, United Airlines and the FAA.
