However, the plane went down before 4:30 p.m. on Monday, crashing into West Acres Mobile Park just short of the Steamboat Springs Airport, officials said.

The crash caused fires at two homes, and numerous firefighters and off-duty personnel responded to the scene, according to officials. All residents of the mobile park were accounted for, but SSFR said the plane’s passengers likely died.

“While the number of individuals within the airplane is still to be confirmed, all occupants are believed to have died in the crash,” Steamboat Springs Fire Rescue said on social media.

Officials secured the area of the crash and notified the National Transportation Safety Board of the crash. The exact cause of the crash is still under investigation.

Officers from Colorado Parks & Wildlife, the Routt County Sheriff’s Office, and the Steamboat Springs Police Department secured the neighborhood after the crash. West Routt Fire Rescue also responded to the scene, while Oak Creek Fire Rescue covered the district and addressed other emergencies.

The Routt County Office of Emergency Management is working with the residents who have been affected by the crash.

There is no further information at this time.
