Tanner W. Byholm
October 4, 1995 - February 16, 2021

Tanner W. Byholm, age 25 of Glidden, Wisconsin, passed away in a private plane accident in Janesville, WI on Tuesday, Feb 16, 2021. Tanner was born October 4, 1995 in Ashland, WI the son of William L. and Rebecca M. (Eder) Byholm.

A graduate student from Chequamegon High School, he pursued a career in aeronautics earning his flight instruction certification from Fox Valley Technical College and later a degree from UW-Oshkosh. Tanner loved flying and shared that love with his family and friends, taking them up in the air as often as he could. He especially enjoyed sharing this love with his dad. He also enjoyed sharing a passion for racing with his dad, first as his biggest fan and then as a fellow competitor. Some of the best races to watch were the races when it was son vs. father. Recently, Tanner started getting into the hobby of competitive shooting. Traveling all over the Midwest competing. During the winter, Tanner took the pleasure of snowmobiling and snowboarding, especially on the many trips out west.

Tanner was a proud Marine Reservist, serving our country for 6 years before deciding to join the Air Force Reserve where he was selected to be an A-10 pilot, the plane of his dreams. He was a person that when you met him, you were drawn in by his presence. He thought of Everyone in his life and will be remembered by all who knew him.

Tanner is survived by his father Bill and stepmother Michelle (Suo), his mother, Rebecca Acosta, sister, Amanda Anderson, brother, Justin Pratt, sister, Eden Byholm, maternal grandparents, Ken & Diane Eder and Bill & Deb Ruth.

He was preceded in death by his paternal grandparents, Virgil and Mary Jane (Noskowiak) Byholm and his uncle, Thomas Byholm.

A funeral service for Tanner will be held at 1:00 p.m. on Friday, Feb 26 at the Lakewoods Resort (21540 Co Hwy M, Cable, WI 54821) with Deacon John Grek officiating with military honors to follow the service.

Visitation for Tanner will begin at 11:00 a.m. on Friday at the Resort in Cable and continue until the hour of service.

In lieu of flowers, memorials are preferred to the American Heart Association (300 S. Riverside Plaza Ste 1200 Chicago, IL 60606-6637). 

Funeral arrangements for Tanner have been entrusted to the Mountain Funeral Home and Cremation Services of Ashland and Mellen, Wisconsin.

Janesville Fire Chief Ernie Rhodes responds to media questions about a fatal Velocity V-Twin experimental aircraft crash south of the Southern Wisconsin Regional Airport on February 16, 2021.

TOWN OF ROCK -  The victims of a fatal airplane crash Tuesday were a man and woman on their way to Florida, according to the Rock County Sheriff’s Office.

They flew over Richard Pawluk, who was walking his dog in the Happy Hollow area Tuesday morning.

Pawluk, 64, was talking to a friend in a driveway near the intersection of Driftwood Drive and Happy Hollow Road.

“All of sudden, it just kind of appeared," he said. “It was kind of climbing. It sounded like it was doing real good, and it banked and it sounded good.

“And then I just heard silence.”

The plane had disappeared below the tree line. Then, “I heard a crunch,” he said.

He handed his dog’s leash to his friend, ran down the road and pounded on the door of a neighbor who is a retired EMT. He told the neighbor he wasn’t sure, but he thought he just saw a plane crash.

“Should I call 911?” he asked. The neighbor called as Pawluk ran into the woods and through deep snow for a distance that authorities estimated at one-quarter mile.

Pawluk called 911 as soon as he saw the debris in an area with springs and flowing water. A dispatcher asked if anyone was yelling and whether there was a fire. There wasn’t, but Pawluk could see steam.

“The landing gear was sticking up out of the water,” said Pawluk, who paused and then sighed, adding: "It wasn’t a pretty sight. …

“I tried to get in closer to the crash site, but it was so muddy. I’d put my boot in places, and I’d sink up to my knee,” he said. “In one place, I had a heck of a time getting my foot back out of the mud.”

Pawluk paused as he described his efforts and thought of the plane’s occupants.

“I wish I could have made a difference,” he said softly.

It appeared the plane went down shortly after takeoff and hit trees before it crashed, authorities said Tuesday. They said the plane’s occupants were dead when rescuers reached the plane.

Sheriff’s Cmdr. Jude Maurer wouldn’t say more about the victims because he didn’t want to indirectly identify them until the Rock County Medical Examiner’s Department had notified relatives.

The medical examiner’s department did not expect to identify the victims Wednesday, a spokeswoman said.

The National Transportation Safety Board said on Twitter that the crash south of the Southern Wisconsin Regional Airport was of a Velocity V-Twin.

A safety board investigator was on the scene Wednesday, Maurer said.

Velocity is a Florida manufacturer of kit, or build-it-yourself, airplanes. Velocity planes feature wings and engines toward the rear. A small wing in the front, called a canard, takes the place of the tail stabilizer on conventional aircraft.

According to a review on the Experimental Aircraft Association website, “The Velocity is not only a high-end performer but also a very stable and safe aircraft to fly. It is virtually un-stallable and un-spinnable.”


Sheriff’s deputies continued to guard the entrance to the site Wednesday. Maurer said he was told the federal agency hoped to remove the plane Wednesday or Thursday.

The crash was reported around 9:18 a.m. Tuesday. It was believed to be the first fatal crash associated with the airport since 1999.


Rock County Sheriff Troy Knudson responds to questions about a fatal Velocity V-Twin experimental aircraft crash on West Sunny Lane, south of Southern Wisconsin Regional Airport, on February 16, 2021. 

Commander Jude Maurer of the Rock County Sheriff's Office points out the location of a Velocity V-Twin that was found in a swampy, wooded area south of the Southern Wisconsin Airport in Janesville on February 16, 2021.  The experimental aircraft crashed shortly after takeoff. 

“It’s nothing you ever want to see. It isn’t pretty,” Richard Pawluk said as he recounted the moment he witnessed a Velocity V-Twin experimental aircraft crash Tuesday morning in rural Rock County.





This drone photo from the Rock County Sheriff's Office shows the area in which the Velocity V-Twin experimental aircraft crashed after taking off from the Southern Wisconsin Regional Airport in Janesville. The area is just south of the airport.

  7. Updated news report quoting NTSB spokesman reveals fuel was purchased at Janesville. Spokesman also clarified the previously undisclosed problem as "shortly after takeoff, the plane indicated the engine problem and announced its intention to return to the airport."

    This info leaves you wondering if the inability of the twin to make it back to the airport in this case is just the reality for one engine out like most light twins or another case of jet-a fuel being loaded after mistaking the unusual looking & sleek piston engine twin pusher aircraft for a turboprop.

    The N326CW mis-fueling incident in 2019 is well known and happened while the pilot was present with the plane. Nozzle didn't fit the 100LL sized ports but the Aerostar still got the jet-a fill.

    1. The velocity is advertised as having positive climb rate ability on one engine.

      Delete
    2. With only two people on board, you would certainly expect that advertised engine out capability to be sufficient if true.

      The 5-gallon header tank described in the 2013 kitplane article would probably delay the effect from a jet-a mis-fuel of the wing tanks until shortly after takeoff. NTSB will be able to easily determine whether a mis-fuel occurred in this case.

  8. Fuel management issues like John Denver? Brand new certified Lycomings going silent. KJVL is a beloved neighbor. I love the sound of aircraft flying out of it. SC Aviation calls it home and I watch their Falcons and Hawkers departing on a daily basis. Sad that we lost two neighbors on Tuesday.

    1. "Fuel management issues like John Denver?"

      Not likely. Denver's aircraft had an unusual placed fuel tank lever location which placed it behind the pilot's seat on the left side to switch tanks. The builder of that aircraft claimed he had a reason for putting it back there instead of where it belongs (between the pilot's legs on the floor up against the center post) in an article I read many years ago but I can't remember what that reason was (I do remember it made no sense to me). Investigators believe that John having to unstrap his belt to reach that lever behind him and to the left may have caused an accidental flight control deflection sending it out of control - and we all know what happens to your body if not strapped into an aircraft experiencing Gs from any angle.

      Delete
    2. Not to imply that the two engines failed on their own, but "Brand new certified Lycomings going silent" is not correct. The registration shows IOX-370 engines. Those are Continental/Titan engines sold for experimental use, not certified, not Lycoming.

      Delete
  9. According to an A&P/AI that I know who knows the plane, it was originally owned by an aircraft homebuilder who decided after many years of working on it, that he wouldn't be able to finish it. he sold it to someone who finished it using the Velocity Builders Program in FL. There was a fuel leak problem with one of the fuel tanks. That's why it was going back to FL. T he Continental/Titan engines, I believe, are sold as both Experimental and Certified engines.

    1. Titan engines were produced by ECI until Continental bought that business in 2015. ECI had been an aftermarket supplier of aircraft piston engine parts since 1943, originally supplying jugs to U.S. armed forces during World War 2.

      https://www.avweb.com/ownership/continental-buys-eci/

      Continental still sells certified engines without an "X" designation. The only Titan engines currently offered are the uncertified engines that are identified by the "X" designation.

  11. No info has been reported about the two hours spent on the ground after landing at KJVL. Was it planned or precautionary?. They had only been airborne about 40 minutes after starting out for Florida from Appleton.

    Could have been a planned stop to eat at the diner in the terminal and make the baseline fuel fill for the first half of the day. Or they could have landed there to troubleshoot a problem.

  13. I wonder if these 2 young pilots were performing a ferry flight to Florida for the student pilot/owner, listed as the same address as "Toys for Trucks" business in Appleton, WI? It appears that this kit plane was recently completed (owner assist program) at the Velocity factory in Sebastian FL, yet has no recent flight log data posted on FlightAware. It was only completed late last year, October based on the factory website marketing video.

    From all indications, and posts from others, it appeared this newly delivered airplane was being flown back to the factory in Florida to have some squawks/fuel leak issues addressed. I can't see where this aircraft had any more than 20 flight hours on it since new, or whether the 2 young pilots flying it were even trained in this rare twin pusher Canard type experimental aircraft before making this ill-fated final flight? So many questions, and the answers will eventually trickle out and hopefully identify the root cause(s) of this tragedy.

  15. On 1/28/2021 this aircraft had an issue from Medford WI to Appleton WI where the landing gear was not extending. After a low pass into KATW where the tower as well as field vehicles could not see the gear extended - the pilot elected to land. At what seemed the last second, the gear extended and landed normally.

    1. Seems impossible to know with any certainty, both being rated pilots and instructors. Can't even tell much by the radio transmissions - either one could make some of the radio calls for the other.

  17. As with ships being advertised as unsinkable, wariness should double when buying or flying any aircraft advertised as virtually unstallable / unspinable, and *especially* a light twin. Even the centerline-thrust models have been unable to escape that.

    ReplyDelete
    Replies
    1. You know that they stalled/spun it in? Interesting. Please elaborate upon how you came to this conclusion.

      Delete
    2. The Reluctant Poster focused on stall/spin, but the same caution applies to the twin's single engine capability. Go read the velocity website entry for the twin and see for yourself that no specific engine out/single engine performance data is stated.

      The N13VT crash has everyone looking for verified-by-test single engine climb rates vs gross weight and engine model. N13VT had the 190 horse 370's, making it the most capable piston version listed, yet the website will only go so far as to state:

      "Our power to weight is higher than most conventional twins thus giving us a better rate of climb should an engine fail."

      What are those climb rates, with the dead engine's prop feathered and not feathered? Regardless of the accident cause, this accident highlights the importance of publishing those numbers, even if only for the IO-370 version.

      Delete
    3. That isn't uncommon at all. For example, Piper and Diamond don't publish single engine performance numbers on their website either. There are too many variables, but it's a given the numbers are in the POH. Kitplanes cited 100FPM climb in their 2013 article. Furthermore, it's silly to discuss single engine numbers as we don't know if it was a single or dual engine failure, partial or complete power loss.

  18. Here's the ADS-B track of the flight. Click on the track to see the info.

    2. That info IS transmitted with some of the newer "glass cockpit" systems.

    3. Thanks, that is a good feature to learn about. Noticed while trying that out how clicking on each data point shown in the Adsbexchange track updates those "extra info" windows to that point's info. :)

      Delete
    4. You are welcome. Yes, if you are watching a particular aircraft, you can actually see the the pilot input on the FMS. Sometimes I'll have Live ATC playing listening to ATC instructions to the pilot,(climb to, descend to, fly heading, etc.), and actually see the pilot changing the input on the FMS. As the aircraft nears the final approach fix it will switch to approach mode, and fly the approach to the MDA/missed approach point.
      Really pretty cool to see. Many more features if you click around.
      Technology has really advanced faster than most people can keep up.

    Doesn't seem to be a spin, but the bobbing canard resistance to stalling ends when you run out of height above ground.

  21. Any comments from the owner of this newly built experimental aircraft yet? It appears that it was registered to the same address as the business, "Toys for Trucks". I'm sure we will eventually read about the root cause(s), once a thorough NTSB investigation is completed.

    ReplyDelete
  22. thru witness sighting site to crash site (approx 1 1/2 mi) reflects a continueing coordianted right departure from Rwy 14.
    The acft is inverted indicating a stall!

    ReplyDelete
    Replies
    1. Inverted when it came to a stop is not unusual when an airplane has a forced landing. The gear will catch and "trip" the plane on it's back. Airplanes that stall usually hit in a severe nose down attitude with a lot of crushing from the front towards the back. NTSB will likely be able to tell us more when they have determined something.

      Delete
    2. The flight data on tracker indicates the plane was in a controlled, stable descent or glide until it hit the trees. It was not inverted, but probably flipped once it hit the trees (which took the wings off) and landed inverted in the water. It appears the pilots did everything right to attempt a stable off field landing but had no open fields in front of them. It appears they did what you are supposed to do--fly the plane ithrough the crash--which in this case was the trees. Velocities are very strong and well built and many have survived off field landings in the past.

      Delete
    3. ADS-B track shows departure on RWY 32, left turning climb, came back around from the south attempting to return. The witness's observation location is described as "in a driveway near the intersection of Driftwood Drive and Happy Hollow Road", but that is north of the flight path and crash site.

      Maybe the reporter got the witness location description wrong. The plane definitely did not overfly the intersection of Driftwood Drive and Happy Hollow Road during the crash sequence.

      Delete
    4. gretnbear.. What are you talking about? The aircraft took of from Rwy 32, then made a left turn to the south, climbed to about 2600' then started a slow shallow descending left turn back toward the airport. They just didn't have enough altitude for the distance needed to reach the airport.

      Delete
    5. the id witness Richard Pawluk lives at 825 W Happy Hollow Rd, SSE from rwy 32. The crash site is approx 1/2 mi S from his home, & 1 1/4 mi SSE from rwy 32s threshold ... Left departure from 32 to 2600,' declares an issue, initiates a continued coordinated left turn for an apparentedly 32 return, yet gravity defeats their attempt by 1 1/4 mi. Again I stand corrected on prior comment.

      Delete
    6. Don't sweat it, GB. Easy to misinterpret the path if you relied on the news story's witness writeup. ADS-B shows that it is not possible for N13VT to have overflown a driveway near the intersection of Driftwood Drive and Happy Hollow Road.

      There was also no overflight of Sunny/Baxter/Baxterwood lanes, either, since the crash was south of all of those streets. :-)

    7. I realize it's a total armchair QB but the flight data shows they directly overflew HWY 51 towards the end of the descent. Always wonder what if... :/

      Delete
    8. They may have considered Hwy 51 while over it, but Velocity web page shows a VTwin landing speed of 85 knots (98 MPH), which can be difficult to fit into non-interstate speed road traffic at 9:15 AM on a Tuesday morning. Heading to Florida with a fuel load, breaching the wings colliding with vehicles is undesirable.

      They would have been coming down somewhere around Blackhawk Technical College. The road there is straight, 4 lanes with a center turn lane. No road crossing power lines from the college until nearer the turn up ahead.

      Here is street view at the college entrance, looking North if you want to roll along and look (paving work is old because old photo):

  24. Where exactly did the pilot radio that they had engine problems? Lat/long per ADSB track needed.

    Note: V-twins do not roll over at Vmc. The airplane performs effectively like a single except for the surprising amount of adverse yaw due to offset of thrust center line.

    1. JVL does not have a Live ATC feed, I am not sure if communications are recorded in the tower or not. The track shows the speed drop, presumably they communicated their problem to the tower shortly after the issue began.

      It doesn't appear that there was a VMC roll, aircraft capable or not. The sheriff indicated that the wings were torn off by trees, in that case there's no roll control so the aircraft rolled on its own after losing all or part of the wings... or flipped upon hitting the water with the gear down.

  25. Vertical rate of climb went from +1400 fpm to -128 fpm at 42.604°, -89.082°, time 15:13:39. Unknown whether they pulled back throttle or power dropped on its own.

    No Liveatc recording there, timing of radio call may not be able to be determined.

  26. Didn't hear of a fuel leak problem, but I did hear they were planning on flying it down to Sebastian with the gear extended. I'm not sure if the airplane would climb dirty. I'm sure some of the links in this chain included new pilots to the aircraft, not wanting to ding someone else's new airplane, gear not able to retract.

    1. Flying gear down for a factory visit fits with the flight record seen in ADS-B - no flights between the 28 January gear trouble day and the February 16 accident day.

  28. Pilots saw a problem by the time they completed the initial turn south right after takeoff. (Based on one minute sixteen seconds elapsed time from takeoff clearance to trouble call per the NTSB preliminary report).

    Trouble call would have been at the 15:13:08 data point or sooner (Using sixteen seconds for acceleration from takeoff clearance to first ADS-B data point at 15:12:08).

    1. Where are you reading the preliminary? CAROL shows it but clicking the PDF is a dead link at this time.
