Three people sustained "serious" injuries after a fire ignited on 17 September in the cargo hold of a Boeing MD-11 freighter operated by Western Global Airlines, according to the US Federal Aviation Administration.

The fire occurred on the ground at about 15:50 local time, while the aircraft was undergoing maintenance in a hangar in Oscoda, Michigan, according to the FAA's preliminary report.

"Three people were burned and the Oscoda fire department responded," an FAA spokesperson tells Flightglobal. The agency's staff at Grand Rapids are investigating, the spokesperson adds.

The National Transportation Safety Board and the Oscoda-Wurtsmith Airport Authority did not immediately provide more information.

The aircraft, registration N415JN, is operated by Western Global and owned by a company called M48415 LLC. Neither company could immediately be reached for comment.

The MD-11 was delivered new to Taiwan's EVA Air in 1994 and is powered by General Electric CF6 80C2D1F turbofans, according to the Ascend Fleets database.

Western Global operates three MD-11s, according to Ascend.
