Federal Aviation Administration / Flight Standards District Office; Scottsdale, Arizona
Location: Three Points, Arizona
Accident Number: WPR22FA012
Date and Time: October 17, 2021, 14:02 Local
Registration: N112LS
Aircraft: Rockwell 112
Injuries: 1 Fatal
Flight Conducted Under: Part 91: General aviation - Personal
On October 17, 2021, about 1402 mountain standard time, a Rockwell International, 112B airplane, N112LS, was destroyed when it was involved in an accident near Three Points, Arizona. The pilot was fatally injured. The airplane was operated by the pilot as a Title 14 Code of Federal Regulations Part 91 personal flight.
Recorded Automatic Dependent Surveillance-Broadcast (ADS-B) data provided by the Federal Aviation Administration (FAA) showed that the airplane departed from runway 24L at Ryan Field (RYN), Tucson, Arizona, about 1339, ascended to 4,500 ft mean sea level (msl) and traveled southwest for about 5 minutes before conducting multiple 180 degree turns over a road. The data showed the airplane
continue to the southwest before making a wide right turn followed by a left turn. The data showed 2 lazy-eight type maneuvers before heading southwest. The data showed that the airplane’s airspeed slowed to about 50 mph and entered a descending left turn. The airplane continued in a descending left turn until ADS-B contact was lost at 1402, at an altitude of 3,250 ft msl (250 ft agl).
Concerned friends of the pilot contacted local authorities after the airplane was overdue at its planned destination. The airplane wreckage was found later that evening by local law enforcement.
A friend of the pilot reported that the pilot was preparing for an upcoming biannual flight review scheduled for the following week.
A postaccident examination of the accident site revealed that the airplane impacted terrain in a flat, wings level attitude. The airplane remained mostly intact but was consumed by postimpact fire. Broken plexiglass surrounded the main wreckage. All the airplane’s flight controls were found at the accident site and flight control cable continuity was established to the cabin area.
The airplane was relocated to a secure facility for further examination.

Dr. Tim Krone
The pilot who died in a plane crash west of Green Valley on Sunday has been identified as a local veterinarian, but in every aspect of his life Dr. Timothy Krone was much more.
Krone was the lone occupant of a Rockwell Commander 112B that crashed about 2 p.m., 20 miles southwest of Ryan Airfield, where the flight originated. He was 44.
The cause of the crash is under investigation by the National Transportation Safety Board and a report is expected in the next two weeks.
The fixed-wing, four-seater was built in 1976 and was registered to Krone, according to FAA documents. According to two flight-tracking websites, the plane left Ryan Airfield west of Tucson at 1:39 p.m. Sunday and was last seen 23 minutes later. The wreckage was found southeast of Kitt Peak, about 25 miles west of Green Valley.
‘A huge shock’
Krone joined the Animal Care Center of Green Valley in 2016 as a relief doctor and became a permanent member of the staff in May 2020.
“He meant the world to our practice,” said Otto Siegler, Animal Care Center’s practice manager.
Siegler said most of their vet techs studied under Krone, who was program director for the Veterinary Technology program at Pima Community College from 2011-20.
“He continued to be a mentor to people here every day,” Siegler said Thursday.
The Animal Care Center closed Monday and Tuesday, and on Wednesday sent an email to clients.
“This has been a huge shock to all of us,” it read in part. “Dr. Krone was our colleague and friend as well as an important member of our Veterinary Community. We will all miss him far more than words could ever express.”
Amber Nix, shelter manager at the Hermitage No-Kill Cat Shelter and Sanctuary in Tucson, called Krone “one in a million.”
“He was compassionate, he was good with all our staff and all our volunteers,” she said. “Nobody was beneath Dr. Krone.”
Krone worked there once a week since January 2020, and successfully integrated cats with medical challenges into the general cat population who may have been euthanized in other shelters, she said. He also trained staff, interns and externs.
“He was just a really big part of what we did here at Hermitage,” Nix said.
Krone devoted himself to animals and those who wanted to work with them, volunteering, training and caring throughout Southern Arizona.
Krone wrote in a biography on the Animal Care Center website that he became interested in veterinary medicine from an uncle who had a practice in Ohio.
“I stayed focused on the path to becoming a veterinarian. I have a curiosity and passion for learning about our world and am humbled by how domestic animals let us share in theirs and respond to our medical care,” he wrote.
Krone grew up in Detroit and graduated from Michigan State University College of Veterinary Medicine in 2001. He then completed a yearlong internship in 2002 at Washington State University, Veterinary Teaching Hospital.
Not coming home
Kathy Hagen looks around the Tucson home she shared with Krone and sees memories everywhere — from the earthworms he used in gardening and composting to nearly two-dozen orchids he grew. They were together 16 years after meeting on the job at a Tucson emergency animal center.
“It’s been rough,” said Hagen, who lost her mother last month. “I luckily have really good friends and I have my family, and Tim’s family is treating me very well. But it’s been different not having him come home every day like he’s supposed to.”
She ticks off a list of what made Krone special, right down to acting as a stepdad for her children. It makes her smile.
”He was kind, he was caring, he was giving. He was selfless. He would do anything for anybody above anything for himself,” she said. “His favorite saying was he didn’t know those two letters — N-O.”
That commitment to others was born out in page after page of grateful social media posts that Hagen said she is clinging to as she deals with the loss.
“I’m overwhelmed and appreciative of the outpouring, of just the words and the kindness and everything that’s coming from people, many that I don’t know,” she said.
She said she was told by the Pima County Office of Medical Examiner on Thursday that Krone had been positively identified through dental records. She said he had no medical issues.
”We’ll wait and see,” she said of a cause. “I just know he’s not here.”
Chief Medical Examiner Dr. Gregory Hess confirmed the finding Friday to the Green Valley News.
Hagen said Krone was out flying Sunday preparing for annual flight proficiency testing he was to undergo on Tuesday.
“He got a lot out of life. He didn’t sit still very long,” she said.
She said Sunday was typically their one day together, “until that one Sunday. But it was doing what he loved, and I just hope it was painless and without fear for him.”
”He is flying high now and he was a Christian, so I know he is in heaven.”
Dr. Timothy M. Krone
TUCSON - A local veterinarian was identified as the pilot who died in a plane crash on Sunday.
At the Hermitage Cat Shelter and Sanctuary, Dr. Timothy Krone worked part-time to help several kittens get ready for their forever homes.
Krone was the one who made it possible by spaying and neutering the felines.
Just before newly named "Krone" was brought to the shelter, someone had made a sizeable donation to benefit diabetic cats.
"We just felt that was Dr. Krone sending us a message with this cat and looking at him and what a big studly cat he was, we just said, 'You know what? This is him, telling us it will be okay," Vet surgical tech Tiffany Naylor said. "And so we just decided we needed to name a cat after him."
Naylor worked along side Krone every Wednesday when he came in for surgeries.
He not only spayed and neutered cats, he did dental work, eye surgeries and mentored vet students.
"He's amazing. He is one of the most patient people I've ever known in my life," Naylor said. "He was always willing to teach, he loved what he did. You could tell the passion he had for being a veterinarian."
A bundle of kittens brought a bundle of joy to Dr. Krone.
"He cared about the kitties so much," Korina Levine of Hermitage Cat Shelter & Sanctuary said. "He cared about the patients, and he was just an amazing human being."
Outside the Hermitage Cat Shelter and Sanctuary, the recently built pergola by an Eagle Scout Troop 2020 will soon be named in memory of Krone.
"His loss is going to be really tough because he is one of those veterinarians that is truly irreplaceable," Levine said.
Krone may be gone, but what he did for this community and this shelter will live on forever.
A GoFundMe account has been set up for the family of Krones. To donate, click here.
