United Airlines Flight 173 was a scheduled flight from John F. Kennedy International Airport in New York City to Portland International Airport in Portland, Oregon, with a scheduled stop in Denver, Colorado. On December 28, 1978, the aircraft flying this route ran out of fuel while troubleshooting a landing gear problem and crashed in a suburban Portland neighborhood near NE 157th Avenue and East Burnside Street, killing 10 people on board.[1][2][3][4][5] The accident prompted the development of crew resource management in aviation.
As the crew prepared for a final approach for an emergency landing on runway 28L, they lost the number one and number two engines to a flameout, at which point a mayday was declared. This was the last radio transmission from Flight 173 to air traffic control; it crashed into a wooded section of a populated area of suburban Portland, about six nautical miles (11 km; 7 mi) southeast of the airport.[8]
