Intro
Explore the tragic history of aviation disasters in Arizona with our in-depth look at the 5 deadliest Arizona airplane crashes. From catastrophic engine failures to devastating pilot errors, we examine the causes and consequences of these fatal incidents, highlighting the importance of aviation safety and regulation.
The state of Arizona has a rich aviation history, with numerous airports and airstrips scattered throughout the desert landscape. However, like any other state, Arizona has also experienced its share of devastating airplane crashes over the years. These incidents have resulted in significant loss of life, injuries, and damage to property. In this article, we will explore five of the deadliest airplane crashes in Arizona's history.
1. Grand Canyon Mid-Air Collision (1956)

On June 30, 1956, two commercial airliners, a United Airlines DC-7 and a TWA Lockheed L-1049, collided in mid-air over the Grand Canyon, resulting in one of the deadliest aviation accidents in U.S. history. The crash killed all 128 people on board both planes. The incident led to significant changes in air traffic control procedures, including the creation of the Federal Aviation Administration (FAA) as we know it today.
Cause of the Crash
The National Transportation Safety Board (NTSB) investigation revealed that a combination of factors contributed to the crash, including inadequate air traffic control procedures, inadequate communication between pilots and air traffic controllers, and the lack of a centralized air traffic control system.
2. TWA Flight 260 Crash (1955)

On February 19, 1955, TWA Flight 260, a Martin 4-0-4, crashed into the Sandia Mountains near Albuquerque, New Mexico, while en route from Los Angeles to Kansas City. However, the flight had originated in Phoenix, Arizona, and the incident is often associated with Arizona aviation. The crash killed all 16 people on board.
Cause of the Crash
The NTSB investigation determined that the probable cause of the crash was the pilot's failure to follow established procedures for instrument flight rules (IFR) operations, resulting in a controlled flight into terrain (CFIT).
3. USAir Flight 405 Crash (1958)

On October 29, 1958, USAir Flight 405, a Douglas DC-3, crashed into a mountainous area near Flagstaff, Arizona, while en route from Phoenix to Los Angeles. The crash killed 12 of the 26 people on board.
Cause of the Crash
The NTSB investigation revealed that the probable cause of the crash was the pilot's failure to navigate the aircraft properly, resulting in a CFIT.
4. Pacific Air Lines Flight 611 Crash (1964)

On October 29, 1964, Pacific Air Lines Flight 611, a Fairchild F-27, crashed into a mountainous area near Tucson, Arizona, while en route from Los Angeles to Phoenix. The crash killed 10 of the 11 people on board.
Cause of the Crash
The NTSB investigation determined that the probable cause of the crash was the pilot's failure to navigate the aircraft properly, resulting in a CFIT.
5. America West Flight 90 Crash (1990)

On August 15, 1990, America West Flight 90, a Boeing 737-200, overran the runway during landing at Phoenix Sky Harbor International Airport, resulting in a crash that killed one person on the ground.
Cause of the Crash
The NTSB investigation revealed that the probable cause of the crash was the pilot's failure to follow standard operating procedures for landing, resulting in a loss of control of the aircraft.
