NTSB narrative
According to the pilot of the weight shift controlled trike, he had spent several hours trying to start the trike on the previous day without success. He recalled that on the morning of the accident, with the ignition off, he sprayed ether into each of the carburetors and pulled several times on the engine's starter cord. He reported that he then turned on the ignition, pulled the starter cord once, the engine started and the trike accelerated forward. He recalled that the trike rolled over the chalks that were in front of the wheels, drug him for about 100 feet before he released the cord, and the trike became airborne. The trike was airborne for several seconds before impacting the rooftop of a hangar and sustaining substantial damage to the wing keel and the control bar.
The pilot reported that there were not any pre-accident mechanical failures or anomalies with the trike that would have precluded normal operation prior to the accident.
The pilot reported that in hind sight, he should have placed the hand throttle to idle before pulling the cord.
Probable cause
The pilot's failure to adequately secure the aircraft while manually starting the engine from outside the cockpit, which resulted in the unmanned aircraft becoming airborne and colliding with a hangar roof.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2016-05-04.
