Too much moose meat and antlers strapped to a wing caused a deadly small plane crash in Alaska, a nearly two-year long investigation by the National Transportation Safety Board determined in a report released Tuesday.

A plane that crashed and killed the husband of then-U.S. Rep. Mary Peltola, D-Alaska, two years ago was overloaded with moose meat and antlers, federal investigators said this week. Eugene “Buzzy” Peltola Jr., 57, was piloting a Piper PA 18-150 Super Cub when it went down in the mountains northeast of St. Mary’s on Sept. 12, 2023.

A small plane that crashed in 2023 carrying moose meat in Alaska, killing the husband of former U.S. Rep. Mary Peltola, was overweight and encountered drag from antlers mounted outside, the NTSB says.
