Summary
On August 17, 2017, a Aerotechnik L 13 SEH VIVAT (N8230S) was involved in an incident near Moses Lake, WA. All 1 person aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The pilot's improper takeoff configuration due to his failure to follow the pretakeoff checklist, which resulted in a loss of lift and collision with obstacles.
According to the powered-glider pilot, during takeoff he noticed a slower than usual acceleration, but continued the departure.
He reported that, "after lift-off the glider exhibited a poor climb rate although the engine was running smooth."
Moments later, the glider stopped climbing, then descended and struck the roof of a building located about 800ft southwest of the departure end of the runway. The glider came to rest upright, after colliding with another structure, and was consumed by a post-crash fire.
The pilot recalled that during the startup sequence, he was, "anxious to get back to my home base" and that he had not used the checklist.
This incident is documented in NTSB report GAA17CA494. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N8230S.
