ABC15 reports that emergency crews responded to the TPC Scottsdale Champions Golf Course, the sister course to the Stadium Course where the Waste Management Phoenix Open is held each February.
At least six people are reported dead. Nobody on the ground was hurt.
Federal Aviation Administration spokesman Allen Kenitzer says the Piper PA-24 Comanche went down in Scottsdale, Arizona, shortly before 9 p.m. Monday.
The single-engine Comanche can have four or six seats.
The names of the victims have not been released yet.
The National Transportation Safety Board is on site and investigating.
