October 16, 1971: Scenic Airlines, Inc., Cessna 402 (N3250Q) Grand Canyon, AZ

ACCIDENT SYNOPSIS:

On October 16, 1971, a Cessna 402 (N3250Q) departed from North Las Vegas Airport (KVGT) en-route to Grand Canyon National Park Airport (KGCN). The air tour flight was being operated by Scenic Airlines and was scheduled to be 90 minutes in duration. Pilot Wayne Leeth age 46, had flown the route more than 600 times and had more than 2,400 hours total time with 415 hours in the Cessna 402.

A fast moving cold front brought snow showers and low visibility that morning as the flight of four tour aircraft made their way eastbound through the canyon. With the ceiling and visibility dropping, the four planes began to turn back for Las Vegas. Captain Leeth was the last aircraft to turn around after attempting to make it over the Shivwits Plateau near Parashant Canyon. Captain Leeth's last radio call was that he was turning back due to weather. The time was 9:45 AM.

With only three of his four planes safely back on the ramp, a concerned John Siebold (Scenic Airlines owner) began to take the steps in an attempt to locate the overdue aircraft. Without success, the official search was under way by 2:00 PM. The weather continued to hamper the search efforts and it wasn't until the next day around noon that the scattered wreckage of N3250Q was discovered on a snow covered plateau. All ten persons on-board were killed.

HISTORICAL SUMMARY:

This crash site took about fifteen years of on and off searching plus a little luck to locate. The published location was vague. The various newspaper articles had the plane crashing either on Mt. Trumbull, Pine Mountain, in Parashant Canyon or near the top of Parashant Canyon. Even more confusing, the NTSB listed the accident location as Colorado City (nearly 60 miles north of the crash site). I tried to narrow it down with the Civil Air Patrol's wreckage location list and it turned out that the listed CAP coordinate was about a mile from the actual crash site.

It wasn't until 2008 I made a random turn in an aircraft near Parashant Canyon that I looked down and there it was. The crash site is remote, but accessible with four-wheel drive vehicle. The site is located within the boundaries of land managed by the Grand Canyon National Park.

A visit to the crash site revealed that even though wreckage remains today, major components were missing and were either salvaged or removed during the accident investigation process. A list of significant components not located at the crash site during my visit included:

Both Continental TSIO-520-VB turbocharged engines.
Both propellers and/or blades.
Both (left and right) wing structures and tip-type fuel tanks.
Both horizontal stabilizers and vertical stabilizer.
Main cabin door (upper and lower doors).
All three landing gear assemblies with wheels and tires.
Many flight instruments and gauges.
Both crew and passenger seats.

Somehow, this historical crash site has escaped the park service's "cleaning process" of removing aircraft wreckage from public lands. The site should be preserved not only as a memorial to those that perished in this disaster, but also as a testament to the perils faced by early air tour pilots when safety technologies to avoid weather and terrain was not available.

I am not sure if the aircraft was equipped with a weather radar system or if video processors are components of aircraft weather radars.

  • IN MEMORY<br />
<br />
At the time, the loss of Scenic Airlines N3250Q was the worst commercial air tour accident in the Grand Canyon. For Scenic Airlines, in operation only four years, it was their first fatal accident. A devastating event for the small family air tour company.<br />
<br />
Myself, having recently spoken with Scenic Airlines founder and former owner John Siebold about the accident and the aftermath. He sadly recalled tragedy as if it was yesterday. For some, the memories of that October day in 1971 are far from distant and never forgotten.<br />
