The death toll from the cargo plane crash that occurred near Louisville International Airport on Tuesday has risen to 14, local media quoted official sources on Friday.

The UPS cargo plane was taking off when the plane's left engine detached after a "large plume of fire" erupted from the left wing, according to the National Transportation Safety Board (NTSB), citing airport surveillance footage.

A child was among the victims. As of Thursday, the nine missing are believed to be near the crash site.

The NTSB investigation team has recovered the aircraft's "black boxes," namely the cockpit voice recorder and the flight data recorder, at the crash site on Wednesday and located the "main component of the engine" on Thursday.

The plane did not require any maintenance on the day of the crash, but it had been in San Antonio for six weeks prior. NTSB said it will "look at every piece of maintenance that was done" during that time.

It is unclear when NTSB will reveal a preliminary report on the crash.

The cargo plane bound for Honolulu crashed near Louisville International Airport, the worldwide air hub for UPS, around 5:15 p.m. local time (2215 GMT) on Tuesday.
