A man and his 10-year-old daughter died today in a plane crash at the Cullman Regional Airport, according to officials.

Airport General Manager Ben Harrison said the crash happened a little after 12:30 p.m. The Federal Aviation Administration has been notified, Harrison said. Officials from the National Transportation Safety Board will arrive tomorrow to take over the investigation.

The victims were Tyler Wesley Walker, 40, and Brooklyn Walker, 10, of Vinemont, according to Cullman County Coroner Jeremy Kilpatrick.

Harrison would not provide any information about the type of plane involved in the crash or how it happened. He said he cannot release that information until after the investigation has begun.

“It’s a very sad day for everyone here and everyone in the flying community,” Harrison said. “We have a very small flying community here and pretty much everybody knows everyone else flying in and out.”

Harrison wouldn’t say whether anyone else was on the ill-fated flight.

The crash did not occur on a runway or taxi-way, so the airport will remain open during the investigation. Several agencies responded to the crash, including the Cullman Police Department, Cullman County Sheriff’s Department, Vinemont Fire Department and Cullman Fire Department. Harrison said the agencies have been working on a response plan since 2014 that they executed after the crash.

“All the agencies did what they were supposed to do,” Harrison said. “This plan went together as we thought it would.”
