Three people died after a Robinson R22 and an Airbus H125 collided Thursday near McMinnville Airport and crashed into a farm field southwest of Portland.
Yamhill County authorities identified the dead as Oregon pilot Tyler Sturdevant, 38, Texas flight instructor Maddie Aasbo, 22, and a student pilot from the U.K. whose name was not released.
Emergency crews were dispatched around 2:15 p.m., and recovery work continued into Thursday evening as Highway 233 and nearby local roads remained closed with no reopening estimate.
Jerry Trimble Helicopters said one aircraft came from its flight school and that it was cooperating with investigators to secure the site and determine what caused the collision.
The FAA and National Transportation Safety Board are investigating the crash near the 650-acre airport, which remained open despite the wreckage field nearby.
