NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The private pilot had just purchased the unregistered amateur-built experimental airplane and was conducting a local personal flight around an airport. Witnesses, one of whom was the airplane’s previous owner, reported observing the pilot “erratically” taxiing the airplane up and down the runway. After watching the pilot practicing on the runway, including a takeoff and landing, the previous owner expressed concern to the pilot about his handling of the airplane and offered to reverse the airplane sale; however, the new owner replied that he felt confident in his ability to master the new airplane based on “hundreds of hours” in a weight-shift trike and his experience in a tailwheel-equipped aircraft.
The witnesses reported that the pilot subsequently took off and then flew the airplane for 5 minutes around the airfield. During landing, the airplane appeared to stall about 3 ft above the ground, bounce, ground loop, exit the runway, and then come to rest. A witness and the previous owner then inspected the airplane and talked to the new owner. The new owner expressed his intention to resume practice. He then taxied down the runway, at one point exiting it to complete a 180-degree turnaround. During the subsequent takeoff, the airplane turned abruptly right about 45 degrees. The airplane lifted off at the runway edge, and it continued to turn to a heading almost perpendicular to the runway. As the airplane began to climb, it rolled right with a nose-high pitch attitude. The airplane passed behind trees out of the witnesses’ view. About 4 seconds later, the witnesses heard a loud crash. The previous owner reported that he could hear the engine under full power until the airplane impacted terrain. A cell phone video of the accident flight was consistent with the witnesses’ statements. A postaccident examination of the wreckage did not reveal any preimpact anomalies.
Toxicology testing identified drugs in the pilot’s blood and urine consistent with the treatment of anxiety, depression, insomnia, and a cold or upper respiratory infection. However, depression does not generally cause the inappropriate overconfidence exhibited by the pilot regarding his ability to fly an airplane in which he had limited experience and in which the flight characteristics were quite different from the weight-control-trike that he did have experience flying. Further, the psychoactive and sedating effects of the combination of the medications did not likely directly lead to the pilot’s observed behavior. Thus, there is no evidence that the pilot’s medical and psychiatric conditions or the medications he was using to treat them contributed to his decision to continue flight in the airplane in which he had little skill or experience. Given the witnesses’ statements, it is likely that the pilot’s overconfidence led him to continue flying the recently purchased airplane without acquiring additional training after nearly stalling it during a previous landing. The pilot’s lack of training also likely led to his erratic handling of the airplane and his subsequent loss of airplane control.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot’s overconfidence, which led to his improper decision to continue flight in the recently purchased, unregistered airplane without acquiring training and to his continued erratic handling of the airplane and subsequent loss of airplane control.
HISTORY OF FLIGHT
On August 24, 2014, about 1130 eastern daylight time, an unregistered Rans S17 airplane, impacted trees and terrain during a takeoff at the Lowell City Airport (24C), near Lowell, Michigan. The private pilot, the sole occupant on board, was fatally injured. The airplane sustained substantial damage. The unregistered airplane was operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed for the flight, and no flight plan had been filed. The local flight was originating from 24C at the time of the accident.
A witness who lived adjacent to 24C saw a small tailwheel airplane taxiing somewhat "erratically" up and down runway 6. The witness also saw a local pilot at 24C. That local pilot told the witness that the airplane had been his and that the pilot in the airplane had just purchased it. The local pilot expressed concern to the witness in reference with what he had seen of the pilot's handling of the airplane and conveyed that he offered to reverse the airplane sale. The new owner replied that he felt confident in his ability to master the new airplane based on "hundreds of hours" in a weight-shift trike and limited experience in a registered tailwheel airplane.
The witness observed the new owner apply full power and take off. According to the witness, the conditions were not ideal for a test flight; winds were relatively light but varying in speed and direction. The new owner flew the airplane for about five minutes around the airfield about 500 feet above ground level (AGL). The witness reported that the pilot's control of the airplane seemed acceptable; the observed turns were smooth and that the pilot appeared to maintain coordination. As the airplane lined up to land the witness observed that the airplane's approach speed seemed high and its descent rate was "rather steep." However, the airplane reached an appropriate airspeed about 10 feet AGL and about 1,000 feet down the runway. The airplane leveled off and nearly stalled before descending further at a very high angle of attack. The airplane appeared to stall about three feet AGL, bounce, ground loop, exit the runway, and came to rest contacting "shrubbery."
The witness and local pilot inspected the airplane and talked to the new owner. The new owner expressed his intention to resume practice. He started the engine and proceeded to taxi down the runway, at one point leaving the runway in what appeared to be an attempt to position the airplane for a 180-degree turn-around within the runway boundaries. He was able to get the airplane turned around, back on the runway and approximately aligned with the runway heading. The new owner subsequently applied what sounded to be full engine power and the airplane turned abruptly to the right at an angle about 45 degrees to the runway heading. The airplane broke ground at the runway edge and it continued to turn to a heading almost perpendicular to the runway. As the airplane began to climb, it rolled to the right with a nose-high pitch and appeared to have a "critically high angle of attack." The airplane passed behind trees where the witness lost sight of it. About four seconds later, he heard a loud crash. He ran in the direction of that sound and saw the airplane laying about 100 yards south of the departure runway.
Another witness, who was the local pilot, indicated that the engine could be heard under full power until the airplane impacted terrain.
A Federal Aviation Administration (FAA) inspector viewed a video of the accident flight taken with a cell phone belonging to a witness. The inspector's report of that the video was consistent with the witnesses' statements.
PERSONNEL INFORMATION
The 67-year-old pilot held an FAA private pilot certificate with single-engine land and instrument airplane ratings. He also held a sport pilot endorsement for weight-shift-control land airplane. The pilot held an FAA third class medical certificate, dated June 24, 1996. The medical certificate was issued with no limitations. The pilot reported on the application for that medical certificate that he had accumulated 600 hours of total flight time and 15 hours of flight time in the six months prior to that medical certificate. At that time, he reported no medical conditions and taking no medications to the FAA.
AIRCRAFT INFORMATION
The accident airplane was a single-seat, high-wing, fabric covered, aluminum tube design Rans S17 airplane. A two-cylinder engine drove a three-blade pusher propeller. According to build paperwork given to an FAA inspector, the airplane's fuel tank was a nine-gallon tank.
METEOROLOGICAL INFORMATION
At 1053, the recorded weather at the Gerald R. Ford International Airport, near Grand Rapids, Michigan, was: Wind 080 degrees at 10 knots, visibility 5 statute miles, present weather mist: sky condition overcast clouds at 1,100 feet; temperature 22 degrees C; dew point 20 degrees C; altimeter 30.10 inches of mercury.
AIRPORT INFORMATION
C24 was a public, non-towered airport, which was owned by the city of Lowell, Michigan. The airport had a surveyed elevation of 681 feet above mean sea level. The airport had three runways: runway 12/30 (2,394 feet by 48 feet asphalt), runway 6/24 (2,700 feet by 100 feet turf), and runway 15/33 (1,940 feet by 100 feet turf).
Runway 6/24 had displaced thresholds, which were marked with three-foot tall yellow cones. Runway 6 obstruction remarks listed 40-foot trees, located 7 feet from the runway, and 78 feet right of centerline. The threshold for runway 6 was displaced based on a 54-foot tree, located 50 feet right, and 1,350 feet from the displaced threshold, which resulted in an approach ratio of 24:1. Runway 24 obstruction remarks listed 48-foot trees, located 27 feet from the runway. Airport remarks listed an 80-foot tree, located 110 feet north of the end of runway 24.
WRECKAGE AND IMPACT INFORMATION
An FAA inspector examined the wreckage on-scene. The airplane came to rest approximately 170 degrees from the takeoff runway heading. There were no ground witness marks consistent with a wheel lock up during the takeoff. No pre-impact anomalies in reference to flight controls were detected. The landing gear wheels spun freely when rotated by hand and the tailwheel also moved left and right without binding.
MEDICAL AND PATHOLOGICAL INFORMATION
An autopsy was performed on the pilot by the Kent County Medical Examiner's Office. The autopsy indicated that multiple blunt force injuries were the cause of death and the manner of death was accident.
The FAA Civil Aerospace Medical Institute prepared a Final Forensic Toxicology Accident Report. The report indicated:
7-Amino-clonazepam detected in Urine
7-Amino-clonazepam detected in Blood
Citalopram detected in Blood
Citalopram detected in Urine
Flufenamic acid detected in Blood
Guaifenesin detected in Urine

Oxymetazoline detected in Urine
Oxymetazoline NOT detected in Blood
0.016 (ug/ml, ug/g) Zolpidem detected in Blood
0.008 (ug/ml, ug/g) Zolpidem detected in Urine
The FAA Forensic Toxicology's WebDrugs website description of 7-amino Clonazepam, in part, indicated it was the predominant metabolite of the antidepressant Klonopin. Klonopin is a sedating benzodiazepine commonly used to treat anxiety.
The FAA Forensic Toxicology's WebDrugs website description of Citalopram, in part, indicated it was an atypical antidepressant, CELEXA, with the selective serotonin reuptake inhibiting (SSRI) action. It is biotransformed to the active metabolite, desmethylcitalopram.
According to medical references, Flufenamic acid is an analgesic available in other countries. Flufenamic acid is not sold for humans use in the United States and is not considered sedating.
The FAA Forensic Toxicology's WebDrugs website description of Guaifenesin, in part, indicated it was an expectorant.
The FAA Forensic Toxicology's WebDrugs website description of N-Desmethylcitalopram, in part, indicated it was a metabolite of citalopram, CELEXA an SSRI used in the treatment of depression.
The FAA Forensic Toxicology's WebDrugs website description of Oxymetazoline, in part, indicated it was a decongestant used in the treatment of nasal congestion. Oxymetazoline is marketed with the name Afrin.
The FAA Forensic Toxicology's WebDrugs website description of Zolpidem, in part, indicated it was Ambien used in the short-term treatment of insomnia.
Klonopin. Citalopram, and Zolpidem carry warnings about sedation and/or psychoactive effects that may affect the ability to safely operate machinery or motor vehicles.
ADDITIONAL DATA/INFORMATION
An Experimental Aircraft Association (EAA) article titled, "Time Is Up For E-LSA Registration," advised that the FAA hard deadline for owners of two-place or "fat" ultralights to submit their aircraft registration (N number) application for converting their aircraft to an experimental light-sport aircraft (E-LSA) was January 31, 2008. The article further, in part, stated:
With the passing of Thursday's deadline, EAA warns its members to be on the lookout for what may appear to be a "really good deal" in the used two-place or "fat" ultralight/light aircraft market. If you're offered a great price on such an aircraft, make certain it has an N-number and an airworthiness certificate. Always understand what you are buying, and be aware that as the buyer, you would be "under the gun" to get it certificated.

LOWELL, Mich.– A 67 year old man from New Mexico was killed after a plane crash at Lowell Airport on Sunday.
According to a release from Kent County Sheriff’s Department, Bryan Bowker died after the ultralight aircraft he was flying in crashed. Officials were called at the scene at 11:37 a.m.
Bowker traveled from Edgewood, NM to purchase the plane. Officials say he successfully flew and landed the aircraft the first time, but after attempting a second take off he lost control and crashed roughly 350 feet south of the runway.
Jeff Ostrander, who runs the flight school at the airport said he was there as the plane came crashing to the ground. Ostrander said during that second take off is when he and another co-worker noticed something wasn’t right.
“He had been doing some practicing with the aircraft, taxiing up and down the runway to become familiar with the ground handling characteristics,” Ostrander said. “I think what probably happened is a aerodynamic stall where in the wing is held at such angle to the wind that no longer provides normal lift and airplanes do not fly in that condition.
Bowker was pronounced dead at the scene. No one else was injured in the crash.
Ostrander said the victim’s wife was in town with him but that she was not there during the incident. She placed a candle for her husband where the crash happened.
The Federal Aviation Administration is reviewing the crash, according to a release.

LOWELL, MI — An out-of-state man died in an ultralight plane crash this weekend in Lowell, authorities said.
Kent County Sgt. Russ Larson said attempts to resuscitate pilot Bryan Bowker, 67, of Edgewood, New Mexico, were unsuccessful after the 11:35 a.m. crash at Lowell City Airport, 730 Lincoln Lake Road.
Larson said Bowker, a veterinarian, drove-in with his wife from New Mexico in an RV to test fly the aircraft on Sunday, Aug. 24. A local owner was selling the blue and green ultralight craft. Bowker was the only person involved in the crash.
Witnesses at the airport said the pilot managed one successful flight before attempting to takeoff and land again. Bowker crashed on the south side of the city-owned airfield after losing control on the second takeoff.
Emergency responders included Rockford Ambulance, Kent County Sheriff's Dept. and Lowell Fire and Rescue. A victims' services unit was assisting Bowker's wife, who witnessed the crash. Neighbors said she might stay with them until her family arrives.
Larson said the Federal Aviation Administration does not investigate crashes involving ultralights because many of them are custom-built.
