On September 28, 2022, about 0900 mountain standard time, a Grumman American Aviation AA5B airplane, N74349, was destroyed when it was involved in an accident near Sahuarita, Arizona. The pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

According to the pilot’s partner, he planned to fly from the Flying Diamond Airport (6AZ8), Sahuarita, Arizona, to Ryan Field Airport (RYN), Tucson, Arizona, to practice touch and go landings and then return to 6AZ8. Automatic dependent surveillance-broadcast (ADS-B) data, provided by the Federal Aviation Administration (FAA), showed that the airplane depart from 6AZ8 about 0830 and travelled to RYN. The airplane made three traffic patterns and then returned to 6AZ8. While on the downwind leg for runway 25, the airplane decelerated to about 59 knots groundspeed, then began to accelerate as it entered the base leg. The airplane’s speed was about 88 knots when it crossed the runway threshold and reduced to about 65 knots when it was mid-field. The last ADS-B data point recorded the airplane about 70 knots near the departure end of the runway.

The airplane came to rest in vegetation covered terrain about 150 feet west of the departure end of runway 25. A postimpact fire consumed most of the fuselage and wings. The top three strands of a barbed wire fence, located at the end of the runway, were fractured. Several bushes and trees between the runway and the wreckage exhibited breaks in the branches.

The airplane was recovered to a secure location for further examination.

Bart Prieve, 76, unexpectedly passed away on September 28th, 2022, in Sahuarita, Arizona just outside of Tucson. He crashed while trying to land his plane, a single engine Grumman American AA5B Tiger. Bart’s dream was to be a pilot. He started his training in Illinois in 1974 and obtained his single engine license in 1976. He had flown in his Tiger since 1978, and it had taken him to many wonderful places, including the Bahamas, Florida, California, Yellowstone National Park, and over the Grand Canyon to St. George, Utah. He also entered his Tiger in air show competitions in Iowa, Texas, and California, winning “Best in Show” and “Best in Class” at a Grumman convention in California in 2005.

Bart was born March 28th, 1946, in Washington, D.C., to Charles and Margaret (Timm) Prieve. His family moved to Milwaukee, Wisconsin, where he spent his childhood. He graduated from Whitefish Bay High School in 1964. During his youth, Bart was heavily involved in DeMolay International, where he served as Master Counselor for the local chapter in Milwaukee, Longvic Raon, and then Master Counselor for the entire state of Wisconsin.

Bart graduated from the University of Wisconsin with a BA with honors in Mathematics in 1968. He began work with AT&T Bell Laboratories in Naperville, Illinois, in the same year and was supported by Bell Labs to get his MS degree (1969), followed by his PhD (1973), in Electrical Engineering at the University of California at Berkeley. His PhD work and thesis were among the first work at Berkeley on computer operating systems. At Bell Labs, he worked on the computer systems used to develop software for large telephone switching systems.

In 1977, Bart was promoted and transferred to Bell Labs’ Holmdel, New Jersey, location, where he started a team to develop UNIX for IBM computers. He transferred to Bell Labs in Denver, Colorado, in 1981, where he continued to work on operating systems. In 1986, he began his work in supporting communication companies that used AT&T products. That work led to many great experiences with companies around the globe. In 1998, he moved to Bonn, Germany, where he worked with Deutsche Telekom. He returned to Denver in 2000, retiring from Bell Labs. He then launched his consulting firm, TIGI (Technology Insights Group, Inc.), working on patent law in telecommunications.

Bart married JoAnn Zelasko in September 1976, although the wedding was postponed by a week to accommodate his baseball team’s end of season celebration. Even after their divorce, they remained on good terms. Their wonderful sons, Daniel, born in 1986, and Stephen, born in 1991, were a constant source of pride to their parents, especially as they achieved success in their own careers. Bart was especially proud that his son, Stephen, was following in his steps to become a pilot, and they often spoke after Stephen’s flying lessons.

Upon retiring, Bart began volunteering extensively at his sons’ schools, and was frequently the only male to serve on the Cherry Creek High School PTO. Softball became Bart’s primary hobby, and he became an instrumental part of Scrap Iron Softball Club. He was installed in the Scrap Iron Hall of Fame and was presented with the Founders Award, the highest recognition the club gives. Bart also coached several teams, making sure that every player batted, and he was one of the originals of the Scrap Iron Diamonds. He also served on the Scrap Iron board of directors.

Bart met Sharon Withrow at a social club in which they shared similar interests in politics. He and Sharon began traveling to softball tournaments throughout the country and eventually she became the scorekeeper for his team. Bart bought a house outside of Tucson, Arizona, in 2011 on an airstrip with a hangar for his Tiger. He and Sharon began wintering in Arizona, where Bart could fly his plane whenever he wanted. He also joined BAJA Sporting Club, and played in the Allison (competitive) League, and even managed a team this past snowbird season. Bart and Sharon also began globetrotting, traveling to different countries around the world, and visited six different continents. They had planned to visit their seventh continent, Antarctica, in November.

Bart was a devoted father and grandfather, and valued his friends and loved ones greatly. Bart is survived by his partner, Sharon, his son, Daniel and his wife Laurie, his son, Stephen and his girlfriend, McAllister, his grandchildren, Charles (Charlie) and Annabelle, Sharon’s son, Eric Withrow and his wife, Susanne, Sharon’s daughter, Laura Mazotti, and her children, Jonathon and Matthew. Bart is also survived by his brother, Charles (Chuz) and his wife, Chris, his sister, Margaret (Meg) Kleeb, and several nephews and nieces. He was preceded in death by his parents, Charles and Margaret, his brother, Ross, and brother-in-law, John Kleeb.

SALISBURY TOWNSHIP, Pennsylvania - The Lehigh County coroner says dental records are needed to identify the victim of Wednesday's plane crash, as the plane exploded with the man inside.

A second person did survive thanks to the quick actions of Ron Diehl, who was doing renovation at the home where the plane crashed.

"He says get my student. I said holy crap there is somebody else in there," Diehl said.

Moments after, Diehl pulled the man out of the cockpit. This, after the Piper PA-28 crashed in front of him, exploding shortly after.

Diehl says he saw a foot amongst the wreckage, grabbed it, and pulled.

"The wing was sticking up in the air. The wing's coming down, it's like literally going to fall right on me and him. I don't know what happened, but I just dove with him and it landed next to me on fire and when that hit then the fire really took off," he said.

There was nothing more the 47-year-old could do, as he said the cockpit looked like a furnace.

He says he was at the Salisbury Township home doing renovation work when the plane came down nearly on top of him.

"I could see the guy's sunglasses in the windshield. I'm not kidding. I just dove out of the way and as I turned around it struck a tree, and just burst into flames. Pieces went flying," he said.

The plane is registered to Pro Flight Aero Services, a flight training school, with a lease at Queen City. It had taken off from the airport before crashing.

The coroner says dental records are needed to ID the victim. The man Diehl saved was taken to the hospital.

Diehl says there was never a moment when he didn't think of his 3-year-old twins and doesn't consider himself a hero, but he certainly saved a life.

"If myself or a loved one was in that situation I would hope someone would try. All you can do is try," he said.

Diehl says when he pulled the man from the plane he was covered in black soot or a similar material.

An autopsy for the victim is set for Friday.

The National Transportation Safety Board says a preliminary report is expected in two to three weeks, which will give some facts and circumstances of what led to the crash. A full report is expected in one to two years.
